In most cases, the lead country, regional and topical contributors also participated in the Global Status Report (GSR) review and validation process.

The Global Trends in Renewable Energy Investment report (GTR) is jointly prepared by the Frankfurt School UNEP Collaborating Centre for Climate & Sustainable Energy Finance, BloombergNEF and UN Environment. The GTR, formerly Global Trends in Sustainable Energy Investment, was produced for the first time in 2007 under UN Environment’s Sustainable Energy Finance Initiative (SEFI). It grew out of efforts to track and publish comprehensive information about international investments in renewable energy. The latest edition of this authoritative annual report tells the story of the most recent developments, signs and signals in the financing of renewable power and fuels. It explores the issues affecting each type of investment, technology and type of economy.

The GTR is the sister publication to the REN21 Renewables Global Status Report. The latest edition of the GTR, supported by the German Federal Ministry of Environment, Nature Conservation and Nuclear Safety, will be published later in 2019 and available at

REN21 is committed to mobilising global action to meet Sustainable Development Goals.
