Suncor Energy's 2015 Report on Sustainability

CALGARY, ALBERTA--(Marketwired - Sept. 8, 2015) - Suncor Energy's 2015 Report on Sustainability discusses the company's approach to delivering environmental, social and economic performance and provides the company's perspective on the role hydrocarbons will play as the world transitions to a low carbon future.

"It's clear our energy system is in an era of change," said Steve Williams, president and chief executive officer. "As we try to meet the growing global demand for energy, hydrocarbons will continue to be a key source of reliable and affordable energy and alternative and renewable energy sources will become a greater part of the energy mix. Oil sands and oil development have an important role to play in meeting our energy needs and we recognize our responsibility to think about our role in the energy system transition and how we work together with broader society on our energy future."

Beyond reporting Suncor's progress in environment, social and economic areas, the report includes frank discussions on topical issues, including:

• A discussion about energy systems and Suncor's values with Steve Williams, president and chief executive officer
• A conversation with Arlene Strom, vice president, sustainability & communications on priorities including greenhouse gas emissions, social progress in our communities and Aboriginal Peoples
• A Q&A on climate change and carbon pricing with Fiona Jones, general manager, sustainability
• A video interview where several employees share their thoughts on Suncor's impact on the environment

Key highlights from sustainability indicators for the year ending 2014 include:

• More than 587,690 trees were planted at our oil sands site
• $463 million was spent with Aboriginal businesses. Since 1999, total spend with Aboriginal businesses amounts to almost $3 billion
• Suncor and the Suncor Energy Foundation contributed over $27.2 million to charitable, non-profit and community groups
• 48.2 hectares of wetland and lake reclamation was completed
• Our combined renewable energy portfolio displaced about 1 million tonnes of carbon dioxide - the equivalent of the annual tailpipe emissions of about 235,000 typical cars
• Our new $190 million wastewater treatment facility was completed and we expect it to recycle between 22,550 and 43,222 litres per minute
• Over $150 million was spent to support research and development of technology across the corporation, through both internal and external pathways

Reclamation at Suncor is a carefully monitored process with two distinct components: (i) transformation of the area, including tailings ponds, into a solid material that can support vegetation, wildlife and landscape restoration, which includes landform design and soil placement; and (ii) re-vegetation in a way that the reclaimed landscape can support vegetation and wildlife as a self-sustaining ecosystem. When Suncor claims that it has reclaimed land or plans to reclaim land, the reclaimed land will have met or is intended to meet the two distinct components identified in this paragraph.
