Beyond known worlds: climate change governance by arbitral tribunals?

A. Renewable Energy Investors as Claimants

Renewable energy-related disputes have emerged as the new frontier of confrontation between investors and states. A number of countries have adopted incentives to attract investments in the renewable energy sector and to increase the production of clean energy. The rationales for public support of renewable energy are multifold. In general terms, public support of renewables is needed because energy production from renewables is more expensive than (and not yet competitive with) energy generated from fossil fuels. Moreover, energy security calls for the diversification of energy sources away from traditional sources. In response to the current global financial crisis, however, states have implemented unprecedented emergency measures to prevent systemic collapse and return to economic stability. (191) These emergency measures include measures affecting the renewable energy sector. Such measures have triggered a wave of investment disputes against states for potential breaches of investment treaty provisions due to the negative impact of such measures on foreign investments. (192) These investor-state arbitration claims expose the state to potential liability. Investor and host state priorities tend to diverge in times of a financial crisis. Investors are concerned with the protection of their investments. The renewable energy sector is "capital intensive," and "government subsidies are still necessary to make them economically viable." (193) A sovereign's priority, however, is working out a prompt and effective resolution of the crisis. Therefore, finding a balance between the right of a sovereign to respond to a debt crisis and the protection of investors' rights under BITs is a source of international tension.

Many of the pending disputes have arisen out of the same set of facts. A number of EU countries--including Bulgaria, the Czech Republic, Spain, Italy, and Greece--have adopted incentives to attract investments in the renewable energy sector and to increase the production of clean energy. (194) Among these incentives was a "feed-in tariff' (FIT) (i.e., a fixed electricity purchase price set higher than market rates and of guaranteed duration). (195) This and other incentives made the renewable energy market particularly attractive to investors since they reduced financing costs. (196)

After the advent of the global financial crisis, however, a number of governments realized that rapid rates of growth in the renewable energy sector could create an "unsustainable social burden" (197) and began to change their renewable energy policies, repealing some of these incentives, eventually reducing the FITs. (198) In fact, as a policy, FITs cost governments a lot, potentially contributing to the escalation of their deficits. (199) In a number of arbitrations, foreign investors are contending that these regulatory changes amount to a violation of the relevant investment treaties' provisions. This section examines a number of case studies.

Consider, for example, Bulgaria. After adopting the 2007 Renewable and Alternative Energy Sources and Biofuels Act (RAESBA), (200) a new regulation governing investments in renewable energy sources, Bulgaria soon "reached its targets and the governmental authorities took measures to restrict the available incentives." (201) As a result, the 2011 Energy from Renewable Sources Act (ERSA) replaced the RAESBA. (202) A 20 percent tax was imposed on the income of solar energy producers, many of which are foreign owned, and the preferential rates for electricity generated by wind and solar power plants were substantially reduced. Several multinational companies considered the possibility "to protect their rights before an international arbitral tribunal." (203) In 2013 EVN, an Austrian company, which had invested in the energy sector, filed an investment treaty arbitration against Bulgaria. (204) EVN based its claim on the Energy Charter Treaty and the Austria-Bulgaria BIT. EVN acquired the privatized grid operation and electricity supply companies in the southern part of Bulgaria in the 2000s. (205) The dispute was sparked by the reform in the renewable energy sector. EVN was under an obligation to pay a preferential tariff to the solar energy producers but, allegedly, Bulgarian authorities failed to do so. (206) This led EVN to bring a claim against the country after a three-month "cooling-off' negotiation period provided for by the Energy Charter Treaty. (207) While the notice of arbitration is not publicly available, potential breaches, which may be alleged by the foreign investors, include breach of fair and equitable treatment due to lack of a predictable and stable legal framework, breach of legitimate expectations, and indirect expropriation of the investor's asset value. In parallel, reportedly, more than fifty solar companies have lodged a complaint against the state's measures at the European Court of Human Rights, alleging violations of the right to property in breach of Article 1 Protocol 1 of the European Convention on Human Rights. (208)

The Czech Republic is also facing several claims in relation to its repealing favorable treatment of solar-generated energy. (209) In 2005, it had adopted a generous FIT payable to "solar generators who fed electricity into the grid." (210) In 2010, however, the FIT was reduced. (211) A bloc of ten foreign investors filed a joint request for arbitration in May 2013, complaining of various measures allegedly affecting their investments in the Czech Republic's photovoltaic (pv) sector. (212) The claimants relied on a number of treaties in their joint request, including the Energy Charter Treaty and Czech BITs with the Netherlands, Germany, Cyprus, Luxembourg, and the United Kingdom. (213) The claimants contended that these rollbacks constitute an indirect expropriation of their investments and a breach of the fair and equitable treatment standard. (214) The Czech Republic, however, objected to the claimants' efforts to join in a single arbitration. (215) It treated the arbitration request as a request to consolidate all of the claims and indicated which claims it would consent to arbitrate together--"because certain claimants were alleged affiliates and/or invested in a common investment in the Czech Republic." (216) Therefore, six arbitral tribunals have been constituted out of the joint claim. (217) In addition, some German investors have filed an investor-state arbitration under the United Nations Commission on International Trade Law (UNCITRAL) Rules and the Germany-Czech Republic BIT. (218) The latter claim differs from the previous claims because it does not rely on the Energy Charter Treaty. (219) The reasons for the failure to invoke the protections of the treaty are not clear. However, "one explanation could lie in the ECT's Article 21, which places important limits on the claims that can be raised in relation to taxation measures." (220)

Spain is facing a steadily lengthening number of investment treaty claims in relation to its own reductions of incentives that it offered previously to investors in renewable energy production. (221) Reportedly, Spain reduced these incentives which constituted "a significant drag on the Spanish economy." (222) In InfraRed Environmental Infrastructure GP Limited and others v. Spain, (223) the claimant, a UK-based investment fund, which had acquired equity participation in solar projects in Spain, alleges that legal reforms affecting the renewable energy sector constitute violations of the Energy Charter Treaty. (224) A number of companies have brought analogous cases against Spain before the International Center for the Settlement of Investment Disputes (ICSID), (225) the Arbitration Institute of the Stockholm Chamber of Commerce, (226) or ad hoc arbitral tribunals pursuant to the UNCITRAL rules. (227)

Other member states of the European Union are facing similar challenges. On February 21, 2014, the ICSID registered the first known claim filed against Italy for alleged violations of the ECT. (228) The claimants are investors in a photovoltaic energy generation project. (229) The claim is related to the notorious "spalmaincentivi," the decision taken by the government to decrease incentives granted in the past to renewable energy producers. Italy has recently withdrawn from the ECT because of cost-cutting efforts. (230) Under Article 47 of the ECT, the withdrawal will take effect one year after the date of notification. (231) However, the ECT will continue to apply to investments made before such date for a period of further twenty years. (232) Greece has also reduced the supposedly guaranteed prices. (233)

Analogous investment disputes are arising under Chapter 11 of the North American Free Trade Agreement (NAFTA). (234) In Mesa Power v. Canada, (235) a Texas-based energy company has brought an arbitral claim against Canada in relation to the province of Ontario's renewable energy program. (236) The investor, which owns four wind farms in Ontario, contends that the province changed the rules by which renewable energy producers can obtain power purchase agreements, favoring other investors. Ontario's 2009 Green Energy Act is a climate change-related measure aimed at promoting renewable energy production and economic growth. Under the Act's Feed-In Tariff Program (FIT Program), the Ontario Power Authority secures renewable energy through long-term purchase contracts with producers of this energy. Under the program, companies benefit from a preferential tariff rate fixed for twenty years. In Ontario, the Green Energy Act has been controversial because of the preferential treatment granted to renewable energy producers vis-a-vis producers of non-renewable energy. When the relevant authorities introduced some changes to the rules for awarding FIT program contracts, the investor filed a notice of arbitration, contending that these regulatory changes violated the fair and equitable treatment standard. The investor also contended that a green energy investment agreement with a Korean-based company discriminated against other energy producers thus amounting to a breach of the national treatment and most favored nation treatment clauses. Finally, the company alleges that Ontario is imposing a number of local content requirements that amount to prohibited performance requirements under NAFTA Article 1106.

B. Challenges to Climate Change-Related Regulatory Measures

Investors who have invested in polluting activities can bring a second type of investment dispute, challenging climate change-related regulatory measures. Foreign investors can and have argued that Kyoto-related measures violate host state obligations under its international investment treaties, including non-discrimination, the fair and equitable treatment standard, and the prohibition on unlawful expropriation. (237) Reportedly, investors have threatened to file investor--state arbitrations if climate change regulation did not include compensation mechanisms for their alleged losses for reducing carbon emissions. (238) In addition, foreign companies could contend that moratoria on polluting activities amount to breaches of investment treaty provisions. The subsections below examine the types of claims that can and have been brought.

1. Expropriation

Foreign investors could (and have) contend(ed) that moratoria on polluting activities amount to a form of expropriation and require compensation. For instance, an oil and gas firm has filed an investment arbitration against Canada over a moratorium on drilling techniques ("fracking") in Quebec under Chapter 11 of the NAFTA. (239) Although the prohibition of fracking is not a climate change-related measure, similar cases can and have arisen with other moratoria related to climate change.

For instance, in Vattenfall v. Germany, a Swedish company sued Germany under the ECT, challenging a regulation requiring the installation of GHG emissions controls on a proposed coal-fired power plant. (240) According to Vattenfall, local opposition to the plant due to climate change concerns (241) delayed the issuance of the required permits for emissions control and water use. In August 2010, the parties settled the dispute, and the proceedings before the ICSID were suspended. The Government agreed that it would issue the relevant permits and relieved the company of its earlier commitments to the Hamburg Government that aimed to reduce the plant's environmental impact on the Elbe River.

Although the case was settled, this section proposes a solution that may help adjudicating similar expropriation claims in the future. In this regard, it argues that the "police powers" doctrine should apply to this type of climate change-related investment dispute claim. (242) According to this doctrine, general regulation, adopted bona fide and in a non-discriminatory manner to protect public health or safety, or to prevent a public nuisance, does not amount to expropriation and cannot be compensated. (243) In fact, states do have the right--and, some would argue, the duty--to restrict private property to prevent a public nuisance. (244) Few would contest that climate change is a severe type of nuisance or common concern of humankind and that states have the duty to prevent and/or mitigate its effects. The legitimate purpose of climate change-related measures can also be inferred by the fact that they are based on scientific evidence (245) as recognized by several international law instruments ratified by the overwhelming majority of states.

The police powers doctrine allows states to adopt measures to prevent a public nuisance such as climate change. It also allows arbitral tribunals to strike a balance between the objectives pursued by climate change law and those pursued by international investment law. Climate change is a common concern of humankind; there seems to be little question about the need to adopt climate change policies. The protection of foreign direct investment is also an important interest of states, as it can lead to the economic development of the host state. The key issue will be applying international investment law while taking into account climate change law.

At the same time, the concept of police powers is not unlimited. Concepts such as reasonableness and proportionality may help the arbitrators to assess whether the modalities of state regulation are suitable and appropriate to achieve the state objective of climate change mitigation and do not constitute a camouflaged indirect expropriation of the given foreign investment. For instance, in a recent arbitration, Servier v. Poland, (246) concerning the denial of marketing authorizations to certain medicines in the exercise of its police powers to regulate public health, the Tribunal held that while it should "accord due deference to the decisions of specialized ... administrators," it "w[ould] also consider the manner in which those decisions were taken and their effect on the Claimants' investments." (247) In particular, the Tribunal found the denial of marketing authorization to be discriminatory and disproportionate, thus amounting to an unlawful expropriation.

2. Discrimination

Foreign investors (in particular those coming from states outside the Kyoto system) could bring discrimination claims against host states' regulatory measures to promote investments under the Kyoto system. (248) This seems a remote hypothesis, given the almost universal ratification of the UNFCCC and, albeit to a much lesser extent, the Kyoto Protocol. Yet, incentives offered by a state for renewable energy projects could be perceived as discriminatory against carbon intensive businesses.

In this respect, a critical issue will distinguish the climate-friendly and carbon-intensive projects in light of the host state's Kyoto commitments. Arguably, the Kyoto requirements constitute a legitimate ground for distinguishing different economic activities. In an earlier arbitration concerning the construction of a parking area in the proximity of a World Heritage Site, the Arbitral Tribunal distinguished two projects on the basis of their different impacts on the conservation of the site, in light of the host state's commitments under the World Heritage Convention. (249) Similarly, one could argue that carbon-intensive investments and climate-friendly economic activities are not "like investments" because they have different impacts on climate change. Therefore, the host state would be able to defend its regulatory measures on the ground that no discrimination is at issue since there is a legitimate distinction between economic activities, which have different impacts on climate change.

Even prima facie discriminatory measures may be found to be justified because of the novelty and complexity of climate change regulation. For instance, a major steel producer, Arcelor, took action before the (then) European Court of Justice (ECJ), (250) alleging discrimination in the design of the EU Emission Trading Scheme (ETS). (251) The company contended that its emission allocation discriminated against its investment as compared to other competing sectors, (252) requested the partial annulment of the European legislation, and claimed damages. (253) The (now) General Court of the European Union, (254) however, dismissed the claim, supporting the scheme's incremental approach of including some sectors while excluding others. (255) The court acknowledged that the various industrial sectors were comparable polluters and that all carbon emissions affect the global climate. However, the court held that the differential treatment was justified because of the novelty and complexity of the scheme. (256) According to the court, these features allowed a step-by-step approach. (257) In contrast, discrimination based on nationality may be found to be unjustifiable. For instance, in Nykomb v. Latvia, a foreign investor successfully argued that Latvia had discriminated against its investment, supporting domestic operators while withdrawing its support to foreigners. (258)

3. Stabilization Clause

Other claims could be raised in relation to stabilization clauses in contracts between host states and foreign investors. In general terms, stabilization clauses aim to insulate the project from adverse regulatory changes. While stabilization clauses take different forms, they aim to immunize the investment from political risks, freezing the law applicable to the investment to that which was in force when the parties signed the contract. Authors have cautioned that public welfare regulation may be accommodated through appropriate drafting (259) or interpretation of stabilization clauses. (260)

4. Fair and Equitable Treatment

In addition to the mentioned claims of expropriation, discrimination and lack of stability, foreign investors could contend that changes in the regulatory framework of the host state amounts to a violation of the fair and equitable treatment (FET) standard. A number of arbitral tribunals have interpreted the FET standard extensively so as to include the obligation on the part of the state to protect an investor's legitimate expectations and provide a stable legal environment. For instance, in an ECT arbitration, a company won a case against the host state for a change of government policy, which altered an incentive system for green investment. (261)

Although the FET standard seems particularly vague, it does not protect foreign investors against every type of regulatory change. Is it legitimate for the investor to expect host state not/never to take climate change mitigation measures if they are contradictory to statements made or the legal framework in existence? In broad brushstrokes, protected legitimate expectations stem from specific statements by the relevant state authorities, or can arise from the host state regulatory framework in the event that the state in question has induced a given investor's confidence that the legal framework would remain unchanged for some time. On the one hand, it may be difficult to argue that climate change mitigation measures are not foreseeable, as climate change has made headlines. On the other, as Schill points out, "[T]he protection of the investor's legitimate expectations does not make the domestic legal framework unchangeable or subject every change to a compensation requirement." (262) In this regard, the Saluka Tribunal held that ascertaining whether fair and equitable treatment was breached required "a weighing of the Claimant's legitimate and reasonable expectations on the one hand and the Respondent's legitimate regulatory interests on the other." (263)


What are the main challenges posed by climate change-related investment arbitrations? This Part highlights the main issues that can facilitate and/or impede consideration of the public interest in investment treaty arbitration.

A. Lack of Transparency

From a procedural perspective, the general lack of transparency of investment treaty arbitration is of particular concern. Due to the particular features of investment arbitration and the fact that none of the mentioned disputes have been settled yet, very little information is available. While the number of investment disputes relating to renewable energy is growing steadily as reported by the news, very little is known about the claims and arguments of the parties.

The Energy Charter Secretariat regularly compiles and updates a list of the relevant investor-state disputes related to energy--and thus also renewable energy. (264) However, under the Energy Charter Treaty (ECT) "there is no requirement that such disputes be notified to the Secretariat," nor is the Secretariat involved in the administration of investment disputes. Therefore, the information available on the Energy Charter's website "relies on various public sources ... and includes links to publicly available documents" but "completeness cannot be guaranteed." (265)

The ICSID website lists all of the cases that are registered at the Center. (266) Yet, the list provides very little information, generally mentioning the sector of investors' activity, the date of registration, and details about the constitution of the arbitral tribunals. (267) Moreover, the ICSID website does not generally publish the notice of claim let alone the statement of defense and subsequent documents submitted by the parties. (268) If the parties so agree, the ICSID publishes the award on jurisdiction and the final award. (269) The parties, however, may also opt for confidentiality or request the redaction of specific parts of the awards to protect personal data, business information, and the like. The Stockholm Chamber of Commerce and the International Chamber of Commerce provide even less information.

B. Inconsistent Awards

Procedurally, questions arise as to whether the multiplicity of claims and the diversity of arbitral tribunals can lead to divergent awards on the interpretation of recurring legal and factual issues, as happened most notably in the many claims arising against Argentina in the aftermath of that country's earlier financial crisis. Inconsistent awards can impede the harmonious development of international investment law and jeopardize the coherence and predictability of the same. At the same time, however, inconsistent awards can also promote fruitful dialectics within the system, and improve the ultimate quality of the awards. In fact, if one looks at the jurisprudence related to Argentina's financial crisis, an initial stream of awards consistently holding Argentina liable and awarding damages has been partially annulled by Annulment Committees, and another stream of awards have emerged, which has considered Argentina's response to the financial crisis a legitimate response in light of the public interest. (270)

C. Multiparty Arbitration

Another interesting procedural issue characterizing some climate change-related disputes is the possibility of recourse to multiparty arbitrations. The Convention on the Settlement of Investment Disputes between States and Nationals of Other States (ICSID Convention) (271) and BITs are silent on the issue of mass claims. (272) However, arbitral tribunals have allowed such claims. Given the fact that several disputes can arise out of the same set of facts and regulatory changes, several non-affiliated investors have attempted to bring their claims in a single proceeding. Mass claims concern different investments, albeit of an analogous type, and arise out of the same background facts and legal issues. From the investors' perspective, multiparty arbitrations can promote procedural efficiency, coherent results and the participation of smaller investors who otherwise could not afford to file any claim. In fact, because investment arbitration can be very expensive, (273) mass claims can provide access to justice for individuals who otherwise could not afford to obtain legal representation before arbitral tribunals. From the state's perspective, mass claims can be cost-effective, avoid duplicate efforts to resolve common issues, and prevent inconsistent awards. However, the same advantages can also constitute disadvantages for the host state. In fact, mass claims prevent the state from improving and adapting its litigation strategies. Since even small investors can join the proceedings, these risk overburdening the competent authorities. Moreover, the existence of parallel disputes allows the state to diversify the risk of losing or winning claims. In other words, the state can make good use of inconsistent awards, filing claims for annulment against those awards that ruled in favor of the investor (at least within the ICSID system). Because of these considerations, generally states have opposed collective proceedings.

For instance, in PV Investors v. Spain, several investors filed an investor-state arbitration against Spain due to the recent regulatory changes in the renewable energy sector. Although Spain agreed to constitute a single arbitral tribunal, it then raised a jurisdictional objection to the claimants' bid to have their claims heard in a "consolidated" fashion. (274) The UNCITRAL Tribunal, however, rejected its objections and affirmed its jurisdiction. (275) Other arbitral tribunals have heard consolidated claims. For instance, the Abaclat Tribunal accepted the first mass claim arbitration consisting of 60,000 Italian bondholders. (276) Argentina argued that consent to arbitration does not extend to mass claims. (277) In debating whether express consent was required or whether general consent in BITs would suffice, the ICSID tribunal took a pragmatic approach. It held that mass claims would be an efficient means of dispute settlement as opposed to considering the investor claims individually. (278) The Tribunal reasoned that it would be contrary to the ICSID and BITs' objective to deny the investors an efficient remedy to the dispute. Subsequent arbitral tribunals have adopted the same approach. (279) As the Alemanni Tribunal puts it, "[C]onsent is not more valid by being given twice, any more than it is less valid for having been given only once." (280)

D. Private v. Public Interest

More substantively, these cases show that climate policies may have a varied impact on different actors. Generally, climate policies benefit the public at large because they reduce greenhouse gases, which not only worsen people's quality of life but can also determine drought, famine, and rising sea levels. In specific cases, there may be mutual supportiveness among climate change-related measures, the economic interests of businesses, and the human rights of local communities. This scenario is enhanced by the recent establishment of state incentives for the promotion of renewable energy and the acknowledged linkage between the green economy and sustainable development. (281)

Yet, climate policies can affect the economic interests of corporations, which need to invest in technological upgrades or even convert a given business to a more eco-friendly economic activity. Even investments in the renewable energy sector entail significant economic risks. In fact, the profitability of clean energy projects often depends on subsidies and feed-in tariffs. There is a risk that "once investments are made, public authorities will be tempted to reconsider their commitments." (282) Cuts in subsidies for renewable energy have been criticized by both investors and environmentalists. These cuts may prevent other investors from investing in a renewable energy sector.

However, cuts in subsidies for renewable energy may be indispensable to prevent a financial crisis with foreseeable impact on the polity of the host state. In this context, the arbitrators will have to take into account the various circumstances--financial crisis, state of necessity, and even human rights considerations--that may eventually justify a change in the relevant regulatory measures.

These cases will contribute to the development of the investment and climate regimes; at the same time, it would be advisable that practitioners and adjudicators take their impact into account. Given the fact that arbitral tribunals often adjudicate issues related to the public interest, an equilibrated approach to interpretation seems demanded by the need to balance the interests of the state and those of the investor. In this regard, some scholars have argued that "preference for one interpretation over another should be based on a comparison of the consequences that would be likely to follow from each interpretation." (283) Among these consequences, the authors include both the flows of foreign direct investment and the realization of human rights and environmental conservation into host states. (284)

For instance, in Continental Casualty v. Argentina, a case arose from measures taken by the state in the wake of its economic crisis in 2001-2002. (285) The Tribunal determined that the non-precluded measures clause (286) should be interpreted as absolving the host state from liability and considered that:

   [T]he Government's efforts struck an appropriate balance between
   th[e] aim of respecting its international obligations and the
   responsibility of any government towards the country's population:
   it is self-evident that not every sacrifice can properly be imposed
   on a country's people in order to safeguard a certain policy that
   would ensure full respect towards international obligations in the
   financial sphere, before a breach of those obligations can be
   considered justified as being necessary under this BIT. The
   standard of reasonableness and proportionality do not require as
   much. (287)

E. The Evolving Role of the European Commission in Investor-State Arbitration

The evolving role of the European Commission in energy-related investor-state arbitrations is part of a larger series of ongoing "thematic dialogues" (on monetary policy, human rights, criminal justice, and security) between public international law and European Union (EU) Law. Whether EU law is just a component of public international law being embedded in and interdependent with the same, or whether it constitutes an autonomous legal order of a quasi-constitutional nature remains a debated issue.

With regard to energy-related disputes, the European Union has played an active and ambitious, albeit controversial, role, seeking permission to intervene as amicus curiae in a number of arbitrations. (288) Amicus curiae briefs create "possibilities for regime interaction." (289) Arbitral tribunals can accept non-party submissions if they consider that such briefs "would assist the tribunal in the determination of a factual or legal issue ... by bringing a perspective, particular knowledge or insight that is different from that of the disputing parties" or "would address a matter within the scope of the dispute." (290)

The move of the European Commission is grounded in two converging recent developments of EU governance. In recent years, the European Commission has "centralize[d] power in the hands of the [European Union]" in matters related to both climate change and foreign direct investments and has moved towards a greater harmonization in both areas. (291) On the one hand, the European Union has "consciously positioned itself as 'leading global action against climate change to 2020 and beyond.'" (292) The renewable energy directive, Directive 2009/28, (293) "establishes a common framework for the promotion of energy from renewable sources and targets for 2020." (294) The directive aims at increasing the percentage share of energy from renewable sources in the European Union's final consumption of energy to 20 percent by 2020. (295) Key drivers of the renewable energy policy include economic competitiveness, climate change mitigation, and energy security. (296) Under the framework, "mandatory national targets have been adopted," (297) and there is "a clear incentive for member states to create the necessary stable policy framework." (298) The Commission can bring infringement proceedings against a member state, if it fails to implement the directive or falls below its target. (299) To meet the targets, the Union acknowledges that investments are necessary. (300) The European Commission has confirmed that "it remains opposed to retroactive changes to renewable energy support schemes, while acknowledging that several Member States like Greece need to reduce their support to renewables in line with ... cost-efficient levels to stabilize the system." (301)

On the other hand, since the 2007 Lisbon Treaty, the European Union has acquired exclusive competence over foreign direct investment. (302) In addition, the European Union and its member states are parties to the ECT. (303) The participation of the European Union in a number of proceedings between EU member states and third countries is required by Regulation (EU) No. 1219/2012 of the European Parliament and of the Council of 12 December 2012, establishing transitional arrangements for BITS between Member States and third countries. (304) Although the European Union does not enjoy a "special procedural status" in investment arbitration, it is clear that it "is not a mere third party to proceedings concerning EU Member States and EU law." (305) In fact, while the European Union can be acting in furtherance of the public interest and a desire of transparency, it has "direct legal interest in the outcome of the dispute." (306)

The European Commission has intervened in a number of intra-EU investor-state arbitrations as amicus curiae, challenging either the arbitral tribunal's jurisdiction or the enforcement of its award. For instance, in Electrabel SA (Belgium) v. Hungary, the Commission intervened as amicus curiae and challenged the Tribunal's jurisdiction under the ECT. The Commission argued that Electrabel, in its capacity as an EU investor challenging an EU measure, should have brought its case before EU courts. The Tribunal dismissed the EU Commission's argument that questions of interpretation of EU law fell exclusively under the jurisdiction of EU courts. It acknowledged that EU member states had agreed to submit questions of interpretation of EU law to the European Court of Justice (ECJ), now the CJEU. The Tribunal concluded, however, that this was not relevant to the case at hand as the claim was brought for a breach of the ECT, not of EU law. (307) So far, arbitral tribunals have generally upheld their jurisdiction, despite the doctrinal debate over the interplay between ECT and EU law. (308)

Against this background, the European Commission has formally sought leave to present arguments in six parallel claims against the Czech Republic being arbitrated under the UNCITRAL procedural rules. (309) These proceedings are brought by investors from the European Union and are based on the ECT and various intra-EU BITs. (310) The Commission has raised "the possibility that these arbitrations may touch upon questions of EU law, and that former benefits and incentives accorded to solar investors could constitute ... state aid that needed to be eliminated in order for the Czech Republic to remain in compliance with EU law." (311) In other words, the measures challenged by foreign investors as breaches of the relevant BIT, could, according to the Commission, be measures that were in furtherance of the country's EU law obligations. Accordingly, concerns arise that "any arbitral award compensating solar investors for losses arising out of the recent rollback of the earlier series of incentives could itself constitute state aid." (312) The move to intervene in the Czech cases forestalled other interventions in subsequent investment arbitrations. (313) In fact, in November 2014, the Commission sought leave to intervene in Charanne and Construction Investments v. Spain and Isolux Infrastructure v. Spain, both under the SCC rules. (314) Non-disputing parties' applications have been filed to intervene in other energy-related ICSID cases against Spain; (315) yet it remains unclear whether these applications have been filed by the Commission.

In an earlier ICSID arbitration, Micula and Others v. Romania, the EU Commission intervened to support Romania's defense stating that "any payment of compensation arising out of this award would constitute illegal state aid under EU law and render the award unenforceable within the EU." (316) However, the Tribunal dismissed the argument, pinpointing that any ICSID award is binding and should be recognized and enforced without review by national courts. (317)

While the Commission has never published any of its applications to intervene or briefs themselves, it considers intra-EU investor--state arbitration incompatible with the EU legal order. According to the Commission the ECT cannot provide a basis for arbitration of intra-EU disputes because such disputes should be brought before the EU courts and tribunals." (318) Rather, in the Commission's view, the ECT would create obligations "only between the Union and its Member States on the one hand and each of the other non-EU countries on the other." (319)

The ECT, however, "contains no explicit disconnection provision." (320) Therefore, the question is whether there may be an implicit disconnection clause--a disconnection clause that should be inferred in the ECT based on treaty interpretation. While both EU member states and the European Union have ratified the ECT, the Commission seems to suggest that this was due to the fact that, at the time, the European Union did not have competence in the field of foreign direct investment. According to the Commission, the ratification of the ECT does not relieve member states from the obligations of EU law and from the jurisdiction of EU courts in settling energy disputes arising within the European Union. (321)

The argument of an implicit disconnection clause has not persuaded arbitral tribunals. For instance, in Electricite de France (EDF) [upsilon]. Hungary, a still-unpublished award, the Tribunal reportedly "affirmed jurisdiction over and awarded damages in relation to alleged violations of the ECT ... notwithstanding an intervention by the European Commission that had contested the tribunal's jurisdiction over the claims." (322) In parallel, reportedly, "a pair of arbitral tribunals [has] deemed it premature for the European Commission to present written arguments in two [renewable energy-related] pending arbitrations." (323) In another case, after failing to persuade arbitral tribunals to decline jurisdiction over intra-EU claims, the Commission enjoined the host state from paying the relevant arbitral award. (324)


Climate change and foreign direct investments have traditionally been dealt with through separate sub fields of international law. Rules belonging to different legal frameworks can conflict. Is international law a fragmented system where norms produced in one of its subfield can be neglected in another? How can arbitral tribunals address conflicts of norms? Is there a way to find a suitable balance between the public interest and investors' entitlements? This Part examines these questions by adopting a two-fold approach. First, this Part will consider the steps that can be adopted de lege ferenda (the law as it should be in the future) for improving the synergy between international investment law and climate change law. Second, this Part will consider the panoply of options that adjudicators may take into account de lege lata (the law as it currently exists) when settling climate change-related investment disputes.

A. De Lege Ferenda

Is there a need for specific amendments to BITs to accommodate environmental concerns, including climate change? In abstract terms, there is a general compatibility between different international law instruments, and many apparent conflicts of norms can be solved via treaty interpretation. Most investment treaties do not include reference to environmental concerns in general or climate change in particular; they tend to be short treaties that include the standards of treatment and a clause on dispute settlement. This does not mean that environmental concerns are completely irrelevant to international investment law and arbitration.

Although not strictly indispensable, some steps can be adopted de lege ferenda for improving the mutual supportiveness between international investment law and climate change law. In recent years, international investment law has gone through a phase of rebalancing aimed at re-empowering states and aligning investment protection with other policy objectives. (325) Recent investment treaties have expressly included reference to climate change in their preambles (326) or have included environmental measures in carve-outs. General carve outs clarify that bona fide regulation designed and applied to protect public welfare objectives, such as protecting the environment, does not amount to indirect expropriation. (327) The inclusion of a provision on general exceptions can allow states to adopt, inter alia, environmental measures. (328) Certainly climate change is an environmental concern. More specific provisions exclude environmental measures from the scope of the dispute settlement mechanism under the treaty. (329) The Energy Charter Treaty adopts a something-in-between approach as it refers to climate change in its preamble (330) and other provisions. (331) Reference to common concerns such as climate change and/or multilateral environmental agreements in the preambles of international investment agreements is a welcome move as it can foster cross-pollination of ideas and an increased coherence between different branches of international law. The same is true for carve outs and general exceptions.

Given the fact that renegotiating investment treaties is a lengthy process, however, some scholars and practitioners have proposed the adoption of a multilateral declaration to enhance the coherence between international investment law and the climate change regime. (332) According to these authors, the multilateral declaration would clarify that international investment treaties do not constrain climate change measures enacted in good faith. As is well known, at the World Trade Organization, a similar declaration was adopted--the Doha Declaration on the TRIPS Agreement and Public Health (333)--to clarify the interplay between the protection of intellectual property and public health. Yet, this has not prevented states from bringing a number of disputes on different aspects of that interplay. Therefore, it may be more appropriate for states--which are the masters of their treaties--to issue binding interpretations. (334) For instance, this has already been done in the context of NAFTA with regard to the interpretation of the fair and equitable treatment clause. (335)

B. De Lege Lata

This section examines the legal mechanisms that can help arbitrators adjudicate climate change-related disputes. While existing investment rules often do not explicitly address the complexities of climate change, they can be interpreted to take climate concerns into account in their operation. The section first addresses the question as to whether security exceptions could be interpreted in an evolutive manner so as to justify climate policies affecting investors' rights. It then assesses whether general treaty rules on hierarchy--namely lex posterior derogat priori (336) and lex specialis derogat generali--(337) may be adequate to govern the interplay between climate change law and international investment law. It concludes considering how customary rules of treaty interpretation as restated by the Vienna Convention on Law of Treaties (VCLT) allow arbitrators to take other international law norms into account when interpreting investment treaties.

While most BITs do not have a general exception clause, some include security exceptions to protect the public order and essential security interests. Although some such clauses adopt an expressly military framing, and therefore would be inapposite to shield climate change measures, (338) others adopt a looser wording, which may be susceptible of evolutionary interpretation. In other words, the term "security" could be interpreted in an evolutionary manner so as to include "climate security." While some tribunals have interpreted the security exceptions in a restrictive fashion by relying on customary law, (339) other tribunals have expanded the meaning of security to include phenomena in addition to and beyond military threats. Therefore, one may wonder whether such security exceptions may be interpreted to include climate security.

Is climate change a security issue? Admittedly, "the language of calamity, urgency [and crisis] ... has pervaded discussions of climate change for ... decades." (340) The Security Council expressed its concern that "possible adverse effects of climate change may, in the long run, aggravate certain existing threats to international peace and security." (341) Climate change has been viewed as a "threat multiplier which exacerbates existing ... tensions and instability ... threatening] to overburden states and regions which are already fragile and conflict prone." (342) Global water wars and climate refugees are depicted as "security threats." (343) The President of the UN General Assembly recently described climate change as a threat "rivaled in its cataclysmic effects only by thermonuclear conflict." (344) However, while climate change is a "potentially disastrous" "long-term problem and process," its "prospective and impending" nature, (345) rightly or wrongly, could not be perceived as requiring an immediate action.

Certainly, in some cases, security exceptions have been interpreted extensively to include financial crisis. For instance in LG&E v. Argentina, (346) the Arbitral Tribunal rejected the argument of the claimants that Article XI of the US-Argentina BIT should be interpreted narrowly. (347) Article XI of the US-Argentina BIT provides: "This Treaty shall not preclude the application by either Party of measures necessary for the maintenance of public order, the fulfilment of its obligations with respect to the maintenance or restoration of international peace or security, or the protection of its own essential security interests." (348) While the claimant contended that "Article XI is not applicable in the case of an economic crisis because the public order and essential security interests elements are intentionally narrow in scope, limited to security threats of a physical nature," (349) Argentina defended the measures it implemented "as necessary to maintain public order and protect its essential security interests," contending that the financial crisis "constitute [d] a national emergency sufficient to invoke the protections of Article XI." (350) In particular, Argentina contended that the measures it had implemented were necessary to protect public order by pointing to "numerous reports of waves of sudden economic catastrophe, massive strikes involving millions of workers, fatal shootings, the shutdown of schools, businesses, transportation, energy, banking and health services, demonstrations across the country, and a plummeting stock market, culminating in a 'final massive social explosion' in which five presidential administrations resigned within a month." (351)

De lege lata, the International Law Commission (ILC) recommends a toolbox of techniques to deal with conflicting norms. (352) General treaty rules on hierarchy--namely lex posterior derogat priori (353) and lex specialis derogat generali--(354) may not be wholly adequate to govern the interplay between treaty regimes because the given bodies of law do not exactly overlap; rather, they have different scopes, aims, and objectives. (355)

However, this does not mean that climate law considerations are irrelevant. If the applicable law is domestic law that incorporates climate law, climate law considerations can be taken into account. Moreover, when interpreting a treaty, arbitrators can take account of other international obligations of the parties according to customary rules of treaty interpretation as restated by the Vienna Convention on Law of Treaties (VCLT). (356) Pursuant to Article 31(3)(b) of the Vienna Convention on the Law of Treaties, treaty interpretation should take into account "any subsequent practice in the application of the treaty." Moreover, pursuant to Article 31(3)(c) of the same Convention, "[t]here shall be taken into account, together with the context: [...] any relevant rules of international law applicable in the relations between the parties." Therefore, this provision properly expresses the principle of systemic integration within the international legal system, indicating that treaty regimes are themselves creatures of international law. (357) That is how the climate change international obligations of states can be considered in the adjudication of disputes before investment arbitral tribunals.

Multilateral Environmental Agreements' (MEAs) provisions have been used to interpret specific investment treaty standards. For instance, in the Chemtura v. Canada case, (358) the Arbitral Tribunal expressly referred to a number of environmental treaties to evaluate the toxicity of a given chemical. In Parkerings u. Lithuania, the fact that the investment would have affected a World Heritage Site protected under the World Heritage Convention was a sufficient condition for distinguishing the project from another, thus precluding the claim of discrimination. (359) The Tribunal took the relevant MEA into account to deny state liability for an alleged discrimination. (360)

In other cases, however, fragmentation and increasingly narrow specialization sometimes produced awards that suffered from failing to situate their analyses within the wider legal or contextual frame of reference. For instance, in Myers u. Canada, Myers, a U.S. company engaged in Polychlorinated Biphenyl (PCB) waste disposal brought an investment treaty arbitration against Canada for its ban on exports of hazardous PCB waste from Canada to the United States. The Arbitral Tribunal held that Canada's export ban was designed to favor Canadian waste companies and did not sufficiently take into account the fact that Canada was a party to the Basel Convention on the Control of Transboundary Movements of Hazardous Wastes and their Disposal. (361) The Basel Convention prohibits the import and export of hazardous wastes from and to countries that are not a party to the Convention. The United States was not a party to the Convention at the time of Canada's ban. Therefore, this should have been taken into account by the Arbitral Tribunal when considering the legitimacy of the export ban.

The interaction between international investment law and other sets of law raises the question as to whether the former is a "self-contained regime." The increased proliferation of treaties and specialization of different branches of international law make some overlapping between the latter unavoidable. However, "international investment law has its roots in general international law, despite its undeniable specificity," (362) and

   [it] is not a self-contained closed legal system limited to provide
   for substantive material rules of direct applicability, but it has
   to be envisaged within a wider juridical context in which rules
   from other sources are integrated through implied incorporation
   methods, or by direct reference to certain supplementary rules,
   whether of international law character or of domestic law nature.


Climate is a global public good that defies traditional notions of territorial sovereignty. Climate is a common and shared resource that is both beyond and within the jurisdiction of every state. Because climate change is a common concern of mankind and can affect populations regardless of state boundaries, a regime complex governs various aspects of the same. To a large extent, various institutions are recognizing the linkages between climate mitigation and the promotion of foreign direct investments and beginning to formulate responses; and this development is encouraging.

What effect can international investment law have on the current efforts to mitigate climate change? The answer to this question is double-edged. On the one hand, international investment law and arbitration may have a positive effect, encouraging investments in renewable technologies and preventing governments from retreating from previous commitments. On the other hand, international investment law and arbitration may have a negative effect on climate mitigation, especially if the state adopts stricter environmental regulations, which can affect investments in the energy sector. In fact, foreign investors can challenges such regulatory measures before arbitral tribunals claiming that they violate investment treaty provisions.

This Article has contributed to mapping the interplay between foreign direct investment and climate change, exploring the recent boom of investment treaty arbitrations in the field. Foreign investors can and have filed claims against the host state alleging that energy policies adopted by the latter amount to a disguised discrimination against their investment or other breaches of investment treaty provisions. Two types of disputes have emerged: the first type concerns the dramatic regulatory change governing renewable energy in the aftermath of the financial crisis. The emergency measures undertaken in response to the global financial crisis have triggered a wave of investment disputes against states for potential breaches of investment treaty provisions, due to the negative impact of emergency measures on investments in the renewable energy sector. The second type of disputes relates to the adoption of climate change mitigation measures, which can be perceived as affecting the economic value of foreign investments in other sectors. The Article has also offered some legal tools for reconciling energy policies with other economic and noneconomic interests.

While arbitral tribunals are not the best forum to adjudicate climate-related disputes, due to their limited mandate and their uneven consideration of environmental concerns in the past, they can contribute to global climate governance. Investment treaty arbitration can provide private actors a useful tool to access justice at the international level and to obtain compensation in case of mistreatment by the host state. At the same time, investment treaty arbitration should not be perceived as a tool to enforce other treaty regimes, as this was not the intention of its founders and could raise more legitimacy concerns than it helps to solve.

Investing in clean energy can mitigate climate change, bring significant economic benefits, and contribute to the commonwealth. Yet, this Article has shown that while foreign direct investment and climate change mitigation are capable of mutually reinforcing each other, the different branches of international law governing this interplay have different underlying philosophies and priorities. Therefore, equilibrium should be sought between climate change mitigation and foreign direct investments in order to reinforce possible synergies in each of these regimes. Whether this is possible in international investment law and arbitration remains to be seen. Certainly, some redrafting and appropriate interpretation of the relevant investment treaties would allow for the consideration of the public interest.

(236.) The Ontario FIT Program was also the subject of two WTO disputes initiated by Japan and the European Union against Canada, regarding Canada's domestic content requirements for equipment in order for solar and wind power generators to participate in the FIT program. Japan and the European Union challenged the program on two grounds. First, they argued that the domestic content requirement discriminated against imported goods thus being inconsistent inter alia with the national treatment provisions of the GATT and the TRIMS. Second, the claimants argued that the program constituted an unlawful subsidy, contrary to the Subsidies and Countervailing Measures (SCM) Agreement. The Panel ruled in favor of Japan and the European Union with regard to the first claim. The Appellate Body upheld that the Minimum Required Domestic Content Levels prescribed under the FIT Programme are inconsistent with Article 2.1 of the TRIMS Agreement and Article 111:4 of the GATT 1994. With regard to the second claim, the Panel did not consider the FIT itself to be a subsidy. The Appellate Body reversed this finding that the complainants had failed to establish a FIT-based benefit for electricity producers. However, it could not confirm the fact of unlawful subsidization.
