The Global Green Economy Index™ (GGEI) measures the green economy performance of 130 countries and how experts assess that performance. The 2021 10th anniversary GGEI will be a special edition tracking progress in these 130 countries over the past decade. 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. To receive data and analysis related to the GGEI, please enter your email here.
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 also useful as the foundation for creating customized sustainability measurement frameworks for a diverse range of stakeholders.
