Environmental Performance Index (EPI) provides cross-country comparisons by measuring environmental performance at the national scale. While assessment at this scale is important, it does not always account for the variations of environmental quality and performance relevant to decision-makers at the regional, provincial, or city level. The EPI supports a number of efforts to respond to the demand for more fine-grained data. To apply and for more information on the initiative ‘Demand for Smart Scaling the EPI’, follow this link.
