Overview for Real Estate Portfolio Owners


GRESB (Global Real Estate Sustainability Benchmark) is a member-led organisation, which sets a global benchmark for environmental, social and governance (ESG) standards. This global standard is set through yearly participation in self-assessments, scoring and peer-to-peer reviews. 


Investors and asset managers rely on GRESB assessments and results to provide a minimum standard for ESG and property portfolio performance.
