Domtar, a North American freesheet paper manufacturer, has extended its licensing deal with the World Wildlife Fund for all Domtar's EarthChoice products, including office paper.

In addition, Domtar will make an annual contribution of $350,000 to WWF from the sale of its EarthChoice products.

"Domtar has been recognized as a leader in sustainable growth in the pulp and paper industry," says Terry Macko, vice president and chief marketing officer at WWF. "The funds generated by this agreement will build upon Domtar's long-standing commitment to supporting WWF's sustainability efforts around the globe. We hope their commitment to source fiber responsibly and promote credible forest certification sets an example for other companies to follow."
