The Global Green Economy Index™ (GGEI) measures both the green economic performance of 60 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 environment & natural capital. Then, the GGEI perception survey collects assessments from expert practitioners on these same four dimensions. Updated data from the new 2016 GGEI will be available for clients from June 30th, 2016. The public report will launch in the fall of 2016.
The GGEI was the first index of its kind, launched in 2010, and today is widely referenced and utilized by policy makers, international organizations, civil society and the private sector. Like many indices, the GGEI is a communications tool that provides nations with a relative measure of their green economic performance and how expert practitioners judge it. Both components of the GGEI are critical to better understanding how countries can leverage data analytics and strategic communications to advance their standing in the global green economy.
