ESG data, benchmarks and portfolio insights

Investors integrate environmental, social and governance (ESG) data into their investment decisions to manage risks and spot opportunities. But to achieve strong returns and meet sustainability goals, these factors must be validated and standardized across assets.

How GRESB supports investors

GRESB is the global ESG benchmark for financial markets. Our membership-based platform allows you to understand and measure the performance of both your portfolio and other GRESB Assessment participants against the most materially relevant environmental, social and governance metrics.

By the industry, for the industry

Established by investors in 2009, GRESB is used by more than 140 institutional investors to monitor their investments, engage with their managers and make informed decisions.

Today, the portfolios of more than 1,500 real estate companies, REITs, funds and developers and more than 700 infrastructure funds and asset operators participate in GRESB Assessments. This broad market coverage provides investors with ESG data and benchmarks for more than $6.4 trillion worth of assets under management.

Comparable and validated ESG data

As an industry-led organization, GRESB designed its reports and tools to make ESG engagement between investors and asset managers as productive as possible. Asset managers self-report data in a standardized format to the GRESB Portal, where it is validated, scored and benchmarked against industry peers. This provides a consistent, globally recognized framework to measure and act on ESG performance.

Using GRESB’s data, you can:

  • Monitor how your managers are responding to risks, opportunities and impacts
  • Analyze the environmental footprint of your portfolio and individual assets
  • Prepare your portfolio for climate-related financial risks and emerging regulations
  • Track progress across your responsible investing commitments
