A values-based segmentation study, the Ecological Roadmap shows how different segments of the public relate to environmental issues - and why. Most Americans care about the environment but don’t like environmentalists and, increasingly, don’t trust environmental advocacy groups. Nonetheless, the report takes a closer look (through statistics, interviews, and other data) at those Americans who could be a vanguard of environmental behaviour - The Greenest Americans - and their place in an America that also houses the UnGreens.
