MONTREAL, June 20, 2012 /PRNewswire/ - To bolster its industry-leading transparency tool, Domtar Corporation (NYSE: UFS) (TSX: UFS) today announced an expansion of its award-winning site, The Paper Trail (www.domtarpapertrail.com).  The move adds more products and an additional mill, among other updates, to help customers learn even more about the environmental and social impacts of Domtar paper.

Since its launch in June 2011, industry observers and sustainability experts, including Joel Makower, Executive Editor of GreenBiz.com, have noted that the site's transparency gives the tool and Domtar credibility. With its third update to The Paper Trail, Domtar's online calculator will now include:

• Two additional products - EarthChoice® Tradebook, the first publishing grade to be highlighted in the tool, and Lynx® Opaque Ultra, a popular commercial printing paper;
• Pictures, stories and a history of Domtar's Nekoosa, Wisconsin mill, where paper making traces its heritage back to 1840;
• Updated environmental impact data for all grades highlighted within the tool, ensuring results are accurate and relevant; and,
• Newly posted pictures and stories for mills previously included in The Paper Trail.

"We're pleased that The Paper Trail has set the standard among today's industry calculators, and we're proud that we've raised the bar even further by providing additional transparency," said Lewis Fix, Domtar Vice-President of Sustainable Business and Brand Management.  "By continually expanding The Paper Trail, we're helping our customers gain a broader understanding of the Domtar story, and a better visibility of where their products come from."

The Paper Trail (www.domtarpapertrail.com) develops personalized reports that measure Domtar products across five categories:  water usage, the distance its fiber travels to a paper mill, greenhouse gas (GHG) emissions, waste send to landfills and renewable energy usage.  The Paper Trail also illustrates how Domtar compares to the rest of the industry in these categories.  In cases where the environmental impact can be improved, Domtar voluntarily discloses the information, as well as the efforts underway to make improvements.
