WWF-Canada and Domtar Sign Forest Conservation Agreement

Toronto, Ontario, Canada, 26 April 2007 --/PRNewswire/ -- WWF-Canada and Domtar have taken their partnership to new heights with an ambitious agreement that solidifies their joint commitment to ensuring the long-term conservation of the Canadian boreal forest, a globally significant forest region. Through this agreement, WWF-Canada--one of the world's leading conservation organizations--will work with Domtar on the following areas:

- To pursue FSC certification, the highest forest certification standard
globally, for all Domtar-managed forestland in Canada;
- To identify important areas for protection on Domtar-managed lands;
- To promote FSC-certified environmentally responsible papers, such as
Domtar's EarthChoice(R) line.

This agreement marks an important milestone for both organizations that serves as a testament to the impact of collaborative business-NGO partnerships, which benefit both business and the environment.

Domtar has been working in partnership with WWF-Canada since November 2003 when it became the first Canadian-based fine papers company to pledge to certify all of its forests and mills to the rigorous FSC standard. Since then, Domtar has achieved FSC certification for 5 million hectares of its forestland, setting an example for others to follow in meeting the challenges of sustainable forest management. The company has also already voluntarily identified areas for protection equivalent to three times the size of Toronto, in addition to government regulated protected areas in their forests. Through this agreement, Domtar and WWF-Canada will continue to identify additional areas for protection within the boreal forest.

"A key part of this agreement involves the joint identification of areas for protection on lands managed by Domtar in the boreal forest, a region that plays a vital role on a global scale for carbon storage, regulating water supply, and providing a home for plants and animals," said Mike Russill, president and CEO, WWF-Canada. "Our partnership with Domtar will also address the management of important conservation values and habitat for key species such as caribou."

Responsible purchasing with Domtar EarthChoice

Responsible purchasing is on the rise in North America as a growing number of corporations and consumers give preference to products that support socially and environmentally responsible practices. Now, more than ever, business leaders and consumers can be assured that they are making a responsible choice when they select paper that is FSC-certified - the only standard endorsed by 85 of the world's leading environmental groups.

"Domtar's commitment to sustainable forest management has long been one of the cornerstones of our business strategy," affirmed Raymond Royer, president and CEO of Domtar. "We believe that internationally recognized, third-party certification of all our activities is the most effective means to provide our customers with objective assurance that the products they purchase come from forests that are managed in a responsible and sustainable way," he added. "Our line of Domtar EarthChoice papers bridges the gap between sustainability and recycling by ensuring that both the virgin fiber and recycled fiber in our papers are FSC-certified."

Domtar supports CN Tower Climb to help fight global warming

To symbolize the "new heights" reached by this agreement, the Domtar EarthChoice team will join WWF-Canada CEO Mike Russill on 28 April to climb the stairs of the CN Tower. They will be joined by 5000 Canadians for WWF-Canada's most important fundraising event, which aims to fight global warming, the single biggest environmental threat facing our world today.
