AES Makes Greenhouse Gas Offset Commitment to Clinton Global Initiative.

ARLINGTON, Va. -- In a pledge to the Clinton Global Initiative (CGI), the AES Corporation (NYSE:AES) today announced it has committed to produce 10 million tonnes of greenhouse gas emission offsets by 2012 and said it will pursue offset development projects under the Clean Development Mechanism of the Kyoto Protocol in Asia, Africa, Europe and Latin America. AES announced its commitment in conjunction with the CGI annual meeting, which opened in New York today.

"AES is proud to help meet the challenge of global warming through projects and technologies that reduce or offset greenhouse gas emissions," said William Luraschi, AES Executive Vice President of Business Development. "AES first began investing in greenhouse gas emission reduction projects in the late 1980's. With this experience and our global platform, we are well positioned to play a leading role in this burgeoning sector, which is a key component of our broader alternative energy strategy."

In April 2006, AES announced the formation of its alternative energy group and plans to invest approximately $1 billion over the next three years in this sector. In addition to pursuing opportunities in renewable energy sources, through its Climate Change and Technology Development (CCTD) group, AES is actively developing offset projects in the agricultural, reforestation, landfill gas, and coal mine methane emission reduction sectors that meet the requirements of the Clean Development Mechanism of the Kyoto Protocol. AES announced its first significant business venture in the greenhouse gas emission offset production sector in May 2006, through the creation of AES AgriVerde. This majority-owned subsidiary will deploy offset technologies in ten developing countries in Asia, Europe and North Africa. AES AgriVerde utilizes a technology to capture methane from agricultural and animal waste sites, reducing net greenhouse gas emissions by approximately 95 percent over traditional organic waste management processes. Once captured, the methane is either destroyed or it is used to generate a renewable source of electricity.

"Methane is a significant contributor to climate change and is 21 times more potent than carbon dioxide (CO2)," said Bill Lyons, AES Managing Director of Climate Change and Technology Development. "In addition to the positive impacts on climate change, the technology deployed by AES AgriVerde also enhances AES's ability to meet new power needs in developing countries and creates numerous local health benefits including cleaner drinking water and soil as well as reduced exposure to mosquito- and other insect-borne diseases."

In addition to developing offset projects, AES's CCTD group also invests in and is working to develop technologies that will either directly reduce greenhouse gas emissions or serve as the underlying technology for new offset project activities. AES also has formed strategic partnerships with Los Alamos National Laboratory and other entities to identify, evaluate, and bring to market new technologies to further reduce greenhouse gas emissions.

Richard Darman, AES's Chairman of the Board, is a member of CGI.
