MONTREAL, March 13 - Domtar Inc. announced today that it has obtained ISO 14001 certification for its forest management practices on all lands it manages and this a full year ahead of schedule. A total of 22 million acres of forestland has been registered. "Achieving this internationally renowned ISO 14001 standard provides further proof of Domtar's commitment to forest sustainability, whereby the resource is used in accordance with the strictest management practices. In addition, it demonstrates our commitment to the public and to our customers that we adhere to rigorous environmental standards for all our forest practices'', said Raymond Royer, President and Chief Executive Officer. The scope of the ISO 14001 environmental management system applies to the planning, supervision and demonstration of forest management practices. These include harvesting, road construction and maintenance, transportation, scaling and silviculture operations. This standard requires introducing exhaustive documentation and monitoring, standardized management practices and provisions along with continuous improvement. In addition, as part of this certification process, Domtar actively sought to be audited by a third party and put in place mechanisms to inform the public of its activities. Members of the Quality Management Institute (QMI) verified the compliance to the environmental management system. They recognized that Domtar forest operations employees have an excellent knowledge of their environmental responsibilities. Domtar chose the ISO 14001 certification because it is an excellent basis for supporting other standards such as those of the Forest Stewardship Council (FSC), which in some cases responds better to the needs of certain stakeholders and customers. Domtar is also actively involved with FSC Canada in developing Regional FSC Certification Standards for both the Canadian Great Lakes-St. Lawrence and Boreal Forest Regions.
