WISCONSIN RAPIDS, Wis., March 21, 2007 – As a part of its continued commitment to sustainable practices, Stora Enso announced today its participation in the U.S. Environmental Protection Agency’s (EPA) Climate Leaders program. By participating in Climate Leaders, Stora Enso North America Corp. has pledged to reduce greenhouse gas (GHG) emissions from its U.S. operations. Launched in 2002, Climate Leaders is an industry-government partnership that works with companies to develop long-term comprehensive climate change strategies. Partners set a corporate-wide greenhouse gas reduction goal and inventory their emissions to measure progress. By reporting inventory data to EPA, partners create a lasting record of their accomplishments. Partners also identify themselves as corporate environmental leaders and strategically position themselves as climate change policy continues to unfold. “While meeting greenhouse gas emissions reduction goals is a challenge, it is a challenge Stora Enso has more than successfully met as a partner in other initiatives designed to contribute toward mitigating the impacts of climate change on the world’s environment,” said Annabeth Reitter, vice president, Stora Enso Environment. “As energy and fuel costs rise, consciously working to identify options to improve energy efficiency is both environmentally responsible and a good business decision.” “Our Climate Leaders partners are demonstrating corporate climate change leadership by embracing energy efficiency, green power and technological innovation as sound business investments,” said EPA Deputy Administrator Marcus Peacock. “Many of the nation’s leading companies are working aggressively with EPA to lower their greenhouse gas emissions in ways that advance President Bush’s climate change strategy.” For more information about Climate Leaders, visit www.epa.gov/climateleaders.
