What does GRESB do?

GRESB assesses the sustainability performance of real estate and infrastructure portfolios and assets worldwide. We offer ESG data, Scorecards, Benchmark Reports and portfolio analysis tools.

Assessment participants receive comparative business intelligence on where they stand against their peers, a roadmap with the actions they can take to improve their ESG performance and a communication platform to engage with investors.

Investors use the ESG data and GRESB’s analytical tools to improve the sustainability performance of their investment portfolios, engage with managers and prepare for increasingly rigorous ESG obligations.
