There is a surge of interest among my MBA students in going to work for a “green company.” Where do I find information on companies that are environmentally friendly?

Shareholders, employees and customers alike are demanding more and more that companies conduct business in an environmentally responsible way. And many are responding by “greening up” everything from the components of their products and the energy used to make them, to the recycled content in their packaging and the way they deal with the waste that their operations generate. Still other companies exist purely to provide environmentally friendly alternatives to mainstream products and services.

Several socially concerned investment firms track corporate environmental records and publish their findings online. One such firm is Light Green Advisors, a Seattle-based investment advisor that helps investors who seek environmentally sound investment opportunities. Their “Eco-Index” ranks the environmental performance of large companies in a wide range of industries.

Other places to look include the lists of socially responsible mutual funds managed by firms like Calvert Group, Domini Social Investments, Green Century Funds and Pax World Funds. Likewise, the Dow Jones Sustainability Indexes include multinational corporations that meet various environmental standards.

A number of non-profit watchdog groups monitor corporate environmental performance as well. One is the Coalition for Environmentally Responsible Economies (CERES), an association of investment funds and environmental groups that helps businesses adopt eco-friendly practices. Some 70 mid- to large-sized companies have formally committed to “continuous environmental improvement” by endorsing CERES” 10-point code of environmental conduct.

Co-op America, based in Washington, DC, offers report cards detailing where more than 300 major companies stand regarding environmental (and other) labor policies and practices. The organization also publishes the National Green Pages, the largest annual directory of America’s leading socially and environmentally responsible businesses.

Even the U.S. government weighs in regarding “green” companies, at least when it comes to commuting. The Environmental Protection Agency (EPA) and Department of Transportation have teamed up on the creation of a “Best Workplaces for Commuters” website. It bases its rankings on corporate offerings such as subsidized public transportation or vanpool passes, telecommuting (working at home) programs—even bicycle racks and showers for the sweaty. According to the EPA, the top 20 companies on the list save 250 million miles of driving and 12 million gallons of gasoline annually, while preventing the emission of more than 186,000 tons of greenhouse gases into the atmosphere.
