Cummins Joins EPA's Climate Leaders, Sets Emissions Reduction Goal.

COLUMBUS, Ind. -- As a part of its continued commitment to sustainable practices, Cummins (NYSE:CMI) today announced its participation in the U.S. Environmental Protection Agency's Climate Leaders program.

By participating in Climate Leaders, Cummins has pledged to reduce its corporate-wide greenhouse gas (GHG) emissions by 25 percent by 2010, against a base year of 2005. The Company will track greenhouse gas emissions at Cummins-managed facilities worldwide that contribute to the Company's net sales.

The GHG reduction goal is in addition to the 20 percent reduction in GHG intensity that Cummins has already achieved from 2000-2005.

"Joining Climate Leaders and pursuing a climate change strategy are the right things for Cummins to do - both from a business perspective and in our role as a steward of the environment," said Christine Vujovich, Vice President, Marketing and Environmental Policy. "Cummins believes it is important to take concrete action to assess opportunities to establish and meet emission-reduction objectives, and invest in new, more efficient products, practices and technologies.

"We have taken many steps to fulfill our corporate environmental mission, which demands that everything we do leads to a cleaner, safer, healthier environment. And while our accomplishments to date have been significant, making the commitment to join Climate Leaders and to establish a GHG reduction goal are natural extensions of the work we already have begun."

Cummins has been collecting GHG emissions data since 1999, focusing on improvements at all sites. The Company has published an annual Sustainability Report since 2003 and was named to the Dow Jones Sustainability World Index in both 2005 and 2006. It is also a member of Climate RESOLVE and participated in the Carbon Disclosure Project in 2006.
