Suncor Energy releases its 2007 Report on Sustainability

Calgary, Alberta (June 25, 2007) - Suncor Energy Inc. today released its 2007 Report on Sustainability — a comprehensive review of Suncor's social, environmental and economic performance for the past two years.

The report, entitled 'A Closer Look at Our Journey Toward Sustainable Development,' profiles Suncor's progress on a wide range of sustainability objectives and also takes a detailed look at four key challenges facing the company: community sustainability, climate change, water management and labour shortages.

"In every edition, we challenge ourselves to be more frank and offer more insight on the impacts of our operations," says Gord Lambert, vice president, sustainable development. "Sometimes it's hard to see it in black and white but that's the value of the report. It helps focus our efforts and keeps us on our path toward sustainability."

Suncor's Report on Sustainability provides a five-year performance trend in a number of key areas. Performance highlights from that period include:

• A two-thirds reduction in employee lost-time injury frequency
• A record $40 million invested in charitable and non-profit causes
• A 14% increase in total greenhouse gas (GHG) emissions. GHG emission intensity remained relatively unchanged
• A 55% reduction in the amount of water used per barrel of oil produced
• More than $5 billion paid in taxes and royalties

Suncor compiled this report in accordance with the Global Reporting Initiative G3 Guidelines — an internationally recognized standard in sustainability reporting. As in previous years, an independent third party verified a number of performance indicators.

Copies of Suncor's Report on Sustainability are available at or by calling 1-800-558-9071.
