Another source of company information would be the Coalition of Environmentally Responsible Economies (CERES)
The CERES principles (http://www.ceres.org/our_work/principles.htm ) outline specific guidelines to be followed for environmental practice and accountability. According to CERES, 70 companies have endorsed their principles (http://www.ceres.org/about/endorsing_companies.htm).
Companies which have submitted performance reports to CERES as well as CERES performance reviews may be found in the Reports section of their website (http://www.ceres.org/reports/main.htm).
