When the modern U.S. environmental movement began in the 1970s, it relied largely on regulation to reduce negative environmental impacts. Companies responded by creating centers of environmental expertise within their organizations. The major focus of a second wave of corporate environmentalism, which began during the late 1980s, was on demonstrating the business value of environmental sustainability to the executive suite. In the 21st century, all jobs are green jobs. Businesses already know that environmental education matters. Environmentally educated employees can improve a business' bottom line. In tough economic times, sustainability practices save money and reduce impact on the environment. The National Environmental Education Foundation (NEEF) set out to explore the current landscape--how far individuals have come in this third phase--by researching how companies are engaging and educating their employees on environmental issues. This report contains findings of NEEF's groundbreaking survey and case studies. The results of the survey and case studies suggest that environmental education is becoming standard practice at many companies though clearly there is no one-size-fits-all model. Most promising is how many companies see that environment and sustainability (E&S) knowledge is valuable, particularly for new hires, and expect it to increase in importance as a hiring factor. Appendices include: (1) Survey questions; and (2) Case study questions. (Contains 6 footnotes and 18 figures.) [Funding for this report was provided by Kimberly-Clark.]
