The Global Green Economy Index™ (GGEI) measures both the green economic performance of 80 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. You can download the new 5th edition of the GGEI by clicking here.
The GGEI was the first index of its kind, launched in 2010, and today is widely referenced and 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.
