GRESB: Top marks – top performance 97 out of 100

Swiss4net and its shareholders attach great importance to sustainability and transparency. In 2025, the company achieved an impressive 97 out of 100 points in the GRESB sustainability benchmark, the leading international rating system for measuring the sustainability performance of real estate/infrastructure companies and funds. We are very proud of this magnificent result.
Swiss4net exceeded even the highest expectations in the audited areas of environment, social and governance, and once again achieved a sensational top result of 97/100 points this year, outperforming both its peer group and all other companies audited by GRESB.

The ESG-Benchmark

In the ESG Benchmark 2025, tangible assets worth more than CHF 8'000 billions gross asset value were put under the microscope. The analysis enables providers to measure their own company against those of the respective peer groups and thus creates a high degree of transparency for all parties involved. The maximum score achievable in GRESB is 100. The GRESB data is used by hundreds of investors and thousands of asset managers to compare investments across portfolios in terms of their sustainability.
