Suncor Energy recognized for climate change reporting practices

Calgary, Alberta (September 25, 2008) — For the fifth consecutive year, Suncor Energy Inc. has been recognized by the Carbon Disclosure Project's "Carbon Disclosure Leadership Index," ranking best among oil and gas sector companies globally. The index highlights companies with the most comprehensive practices relating to climate change governance and disclosure.

"Transparency in our actions and our greenhouse gas emissions performance are central to Suncor's long-term climate change management strategy," said Gord Lambert, Suncor's vice president of sustainable development. "We're proud that our efforts have again been recognized and we will continue to be open with stakeholders about our company's successes and our challenges."

In addition to a commitment to measurement and disclosure, Suncor's climate change action plan also includes investing in research and technology, developing renewable energy, employing emissions offsets and working with the governments and other stakeholders on education and environmental policy development. Emissions reduction efforts have reduced the greenhouse gas intensity of Suncor's oil sands operations by nearly half since 1990. However, with crude oil production more than tripling, absolute emissions have increased. For more information, visit www.suncor.com/climatechange.

The Carbon Disclosure Project represents 385 global institutional investors with more than $57 trillion in assets. The index comprises 67 constituents of the Global 500 Index. Analysis is based on disclosure of greenhouse gas emissions, emissions reduction targets and risks and opportunities associated with climate change.

In addition to being recognized by the Carbon Disclosure Project, in 2007, Suncor was named a Gold Level Reporter by the Canadian Standards Association for our annual climate change report. In our United States operations, Suncor joined the Climate Registry, a North American non-profit organization, as a founding reporter. The registry provides a standardized framework for GHG emissions reporting. Ceres, a coalition of investors, environmental organizations and public interest groups, and the Association of Chartered Certified Accountants awarded a special commendation for Suncor's 2007 Progress Report on Climate Change.
