What: Weyerhaeuser wants to reduce greenhouse gas emissions generated at its Federal Way, Washington headquarters. To make improvements, the company first needed to understand the current size of its carbon footprint:

  -- What quantities of greenhouse gas emissions come from electrical and
     gas consumption at the site?
  -- What emissions are caused when employees drive to work or conduct
     business travel, either by air or by car?

To obtain this information, Weyerhaeuser turned to a Covington high school teacher to research answers and solutions. Tyler Ault, a ninth grade science teacher at Kentwood High School in Covington got hands-on experience to inventory the sources of carbon dioxide emissions at the company's world headquarters in Federal Way. A first year teacher, Ault developed a carbon footprint curriculum that his students will use this year in class.

  -- Meet Ault at the Weyerhaeuser Federal Way campus or in his classroom to
     see how he investigated the size of the company's carbon footprint at
     its headquarters.
  -- Hear him discuss with company scientists how he determined the volume
     and source of greenhouse gas emissions being generated and learn about
     the ways the company is reducing its carbon footprint now and what
     other steps may help in the future.
  -- Learn about Ault's carbon footprint high school curriculum and plans to
     engage students in reducing greenhouse gas emissions.

  Background:

In June 2006, Weyerhaeuser pledged to reduce greenhouse gas emissions 40 percent by 2020 while reducing its reliance on high-priced fossil fuels. A 40 percent reduction in annual greenhouse gases is the equivalent of taking 700,000 vehicles off the road for one year. The company intends to meet this goal principally by harnessing the benefits of a renewable, natural resource -- biomass -- as fuel in the boilers that generate steam and electrical energy in our mills. Other company facilities, like its corporate campus, are looking for ways to also reduce greenhouse emissions. Progress toward the commitment will be reported in the company's annual sustainability report.

Weyerhaeuser's efforts to reduce greenhouse gas emissions are described in more detail in its 2005 sustainability report. For example, the company:

  -- Sequestered 2.6 times more carbon, primarily in wood products, than it
     emitted last year.
  -- Reduced air and water emissions, measured per ton of production that
     are tracked by the U.S. and Canadian governments.
  -- Recovered 6.7 million tons of used paper, or 13 percent of the total
     recycled in the United States.
  -- Has obtained independent certification that:

     - All of the forests it manages or owns in North America meet the
       Sustainable Forestry Initiative Standard or the Canadian Standards
       Association sustainable forest management standard.

TOSA, a program sponsored by the Washington Forest Protection Association, is a six-week summer professional development opportunity designed to provide teachers with first-hand experience about forest-related environmental topics. Tyler Ault is one of the 11 selected Washington teachers participating in the "Teacher on Summer Assignment" (TOSA) program.

Teachers attend workshops and develop lesson plans based on their summer experience that support their specific classroom teaching objectives.

Participating sponsors include Weyerhaeuser and other private forest products companies in Washington and Oregon.

Since the program began in 1995, more than 314 teachers have spent their summers in paid internships throughout Oregon, Washington and North Carolina.

Weyerhaeuser Company, one of the world's largest integrated forest products companies, was incorporated in 1900. In 2005, sales were $22.6 billion. It has offices or operations in 18 countries, with customers worldwide. Weyerhaeuser is principally engaged in the growing and harvesting of timber; the manufacture, distribution and sale of forest products; and real estate construction, development and related activities.
