Based on a monthly survey of 2,500 adults who are nationally representative of the U.S. adult online population, the Green Confidence Index is the first ongoing consumer study of its kind. It gives businesses with a stake in the rapidly growing green economy monthly insights on Americans’ attitudes about and confidence in their leaders and institutions, nationally and locally, as well as in their own understanding of issues and their willingness to make green purchasing choices. The Green Confidence Index is developed by a partnership between GreenBiz.com, Earthsense, and Survey Sampling International (SSI).
