Global Trends in Renewable Energy Investment (GTR) is an annual report jointly prepared by the Frankfurt School-UNEP Collaborating Centre for Climate & Sustainable Energy Finance, BloombergNEF and the UN Environment Programme (UNEP). Global Trends in Renewable Energy Investment grew out of efforts to track and publish comprehensive information about international investments in renewable energy. The 2020 edition of the GTR explores the most recent developments, signs and signals in the financing of renewable power and fuels. Information is presented by type of investment, technology and economy. It also provides an outlook on financing trends for the next decade.

Together with REN21’s annual Renewables Global Status Report (GSR), these two publications provide a comprehensive overview of developments in the renewable energy sector. The 2020 GTR edition was supported by the German Federal Ministry of Environment, Nature Conservation and Nuclear Safety. It was released in May 2020 and can be downloaded at
