Sep 15, 2009. /Lesprom Network/. Weyerhaeuser Company announced that it is the only building materials company named to the Dow Jones Sustainability Index (DJSI) that tracks North American companies in terms of their economic, environmental and social performance. The DJSI follows a best-in-class approach and includes sustainability leaders from each industry on a global and regional level. The annual review is based on an assessment of corporate economic, environmental and social performance, covering issues such as corporate governance, risk management, branding, climate change mitigation, supply chain standards and labor practices. The DJSI results are available to asset managers around the world for a variety of sustainability-driven investment portfolios. “Our viability as a company depends on our long-term commitment to continuous improvement in protecting the land, and nurturing the forest,” said Dan Fulton, President and CEO. “Our inclusion on the DJSI Indices is validation of our belief in the renewable resource – trees - that forms the base of our sustainable business.” “We’re honored to again be included in the Dow Jones Sustainability Index, North America,” Fulton said. “Third-party validation of our sustainability practices is important confirmation for our customers, employees, communities and shareholders that we are on the right path.” Weyerhaeuser is principally engaged in the growing and harvesting of timber; the manufacture, distribution and sale of forest products; and real estate construction and development.
