GRESB: sovereignty score and 8 European alternatives

GRESB is an ESG benchmark and reporting platform for real estate and infrastructure. Real estate and infrastructure funds and their assets complete an annual sustainability assessment, and investors compare the results with those of peer portfolios. The company also offers SFDR reporting and reports on transition risk. Participants work through a web portal, and training and product resources are available online.

GRESB is headquartered in Amsterdam, and its standards are governed by an associated, independent not-for-profit foundation. In April 2024 General Atlantic, an investment firm with offices in New York, took a majority investment. Control therefore sits with a US owner, and US law may apply to the company. The public pages do not state where data is hosted, so the privacy statement should be consulted. A European investor or asset manager should weigh both the ownership and the data location before submitting portfolio data.

Why digital sovereignty matters with GRESB

GRESB is headquartered in NL and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data. The ultimate owner is based in US. Foreign control undermines part of the certainty a European headquarters offers.

Data is hosted exclusively in the EU, so GRESB scores best on data residency.

GRESB is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs GRESB together with your other vendors and gives a total score, a heatmap and the main risk drivers.
