Guidance for GRESB Investor Members

The GRESB Portal is designed to make your ESG engagement with your managers as productive as possible. It’s your attention to ESG benchmarking and transparency that is driving progress towards a future with more sustainable buildings and infrastructure.

ESG Coverage

GRESB ESG data and benchmarks cover USD 8.6 trillion in real estate and infrastructure value including more than 154,000 geo-coded assets. We cover both private and public markets and data is reported to us at both portfolio- and asset-level. Our comprehensive coverage provides an unrivaled set of data and insights for the investment market.

Increase your coverage

By encouraging your managers to participate in GRESB, you will be able to maximize your portfolio coverage for ESG data, and draw more meaningful benchmark comparisons and portfolio insights. You can share this dedicated webpage with your managers to help them understand why you want them to participate in GRESB. Additionally, we have created an example letter for you to download and send to your managers:

ESG data to inform your engagement

As an Investor Member, you can access data and analytics for your investments. You can view individual Benchmark Reports, analyze your portfolio in flexible ways, and export the data for additional analysis.

Benchmark Report

The Benchmark Report contains an indicator-level analysis of the ESG performance of your investments in both absolute terms and relative to peers. It is designed to identify areas of opportunity and risk in your portfolio and deepen your engagement with managers on sustainability issues.

Portfolio Analysis Tool

Using the Portfolio Analysis Tool, you can perform a portfolio analysis for self-selected groups of your investments, including applying weights and customized benchmarks. The tool provides insight into how each investment contributes to the portfolio’s aggregated ESG performance. It also provides a combined environmental footprint of the investment portfolio.

Data Exporter

The Data Exporter provides access to all data points in the Assessments. The datasets are available for download in .csv and .xlsx format so that you can integrate the data more easily with your existing portfolio management systems and use in your own modeling.
