The Global Green Economy Index™ (GGEI) in 2018 will measure the green economic performance of 130 countries and how experts assess that performance. The GGEI performance index uses quantitative and qualitative indicators to measure how well each country performs on four key dimensions: leadership & climate change, efficiency sectors, markets & investment and the environment. Then, the GGEI perception survey collects assessments from expert practitioners on these same four dimensions.

The GGEI was the first green economy index, launched in 2010, and today is the most widely referenced product of its kind internationally, utilized by policymakers, international organizations, civil society and the private sector. Like many indices, the GGEI is used to benchmark performance, communicate areas that need improvement, and show diverse stakeholders how they too can promote progress. The GGEI is particularly relevant today as countries aiming to realize new emission reduction and sustainable development goals will require data and insight to identify the best pathways to a low carbon economy.
