Highlights of TC+ES Milestones

Trexler Climate + Energy Services, Inc. (TC+ES) was founded in 1991 as Trexler and Associates, Inc. (TAA) by Dr. Mark C. Trexler. Trexler founded the firm after leaving the World Resources Institute in Washington, DC. From its beginning, the company has been sought out by major utilities seeking to position themselves for the climate change issue. Until 1997, TC+ES was the only firm in the United States to specialize in providing climate change mitigation services to the private sector.

Some of TC+ES's major milestones involve policy work, while others are successes in the private sector.

In 1988, while still at the World Resources Institute, Dr. Trexler developed the quantification methodology for the first carbon offset project pursued by a major energy company, namely AES's Agroforestry Project in Guatemala.

In 1992, TAA represented Tenaska, Inc. in developing and implement the first fully funded USIJI project, the ECOLAND project in Costa Rica.

In 1996, TAA won the first power plant siting proceeding in which CO₂ mitigation was a significant variable on behalf of the City of Klamath Falls.

In 1997, TAA supported Stonyfield Farm in becoming the first company to offset all of its GHG emissions from its manufacturing facility in New Hampshire. Stonyfield Farm became the first GHG neutral company in the United States.

In 1998, TAA developed one of the major early action crediting proposals considered in the United States on behalf of the CEO Coalition for the Advancement of Sustainable Technologies.

In 2000, TAA managed Shaklee Corp.'s application to become the first company to be certified as Climate Neutralª by the Climate Neutral Network.

In 2002, TAA entered into a strategic alliance with Sumitomo Corp. of Japan, under the terms of which TAA became part owned by Sumitomo Corp.
