The Green Confidence Index (GCI) 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. A GCI of 100 indicates no difference with the initial July 2009 baseline; above 100 means the current month is higher than the baseline; below 100 means the current month is lower than the baseline. The Green Confidence Index is developed by a partnership between GreenBiz.com, Earthsense, and Survey Sampling International (SSI).
