Each year GRESB assesses and benchmarks the ESG performance of real assets worldwide. The GRESB Assessments are guided by what investors and the industry consider to be material issues in the sustainability performance of real asset investments and are aligned with international reporting frameworks, goals and emerging regulations.

The 2020 ESG benchmark covers more than US $5.3 trillion AuM (2019: 4.5 trillion), giving clarity and direction to the real asset investment market as a means to address complex sustainability challenges. GRESB data is used by hundreds of capital providers and thousands of asset managers to benchmark investments across portfolios and understand the opportunities, risks and choices that need to be made as the industry transitions to a more sustainable future.
