This publication launches the Inclusive Green Growth Index, which captures the key dimensions of economic growth, social equity, and environmental sustainability. The index's 28 performance indicators include data over time-and across countries-on various aspects of growth and policy outcomes in areas where higher investment will advance better quality of growth and living standards. Designed as an easy-to-use guide for policy makers and stakeholders in development, the Inclusive Green Growth Index builds on current measures and indices. It is a powerful tool for assessing a country's progress in achieving its development goals.
