GRESB ESG benchmarks grow to cover USD 8.8 trillion and shed light on net-zero momentum across real estate and infrastructure globally 

Amsterdam, October 17, 2023 – GRESB, the global ESG benchmark for real estate and infrastructure investments, has released the results of its 2023 Assessments, which grew to include 2,084 real estate portfolios and 172 infrastructure funds and 687 assets, collectively representing USD 8.8 trillion in gross asset value (GAV).

“Benchmark growth across real estate and infrastructure this year is not just about numbers—it’s about the depth, breadth and usefulness of the data. This increasing dedication and awareness of data quality demonstrates the commitment of global real assets to transparency and sustainability on a broader scale,” said Sebastien Roussotte, CEO at GRESB.

In 2023, GRESB also increased the granularity of the information it collects on net zero, ranging from net-zero policies to commitments and targets, enabling the tracking of this data for the first time.
