Why do companies integrate GRESB in real estate management?
For many companies, GRESB serves as a practical roadmap for embedding sustainability into real estate operations.

A clear example comes from the real estate company Eastnine.
“We joined GRESB specifically to acquire a roadmap for embedding sustainability into a company’s real estate operations. For a small company like Eastnine, it is extremely important to minimize trial and error and adopt best practices from the very beginning. GRESB allowed us to do just that,” says Lilia Kouzmina, Head of Sustainability at Eastnine

Eastnine joined the GRESB assessment in 2022, and according to its 2025 report, the company continues to demonstrate steady growth. According to Kęstutis Sasnauskas, CEO of Eastnine:

“We are entering the new year with a high occupancy rate and surplus ratio, alongside stable financing conditions. Our focus is to capitalise on these favourable market conditions and pursue additional acquisitions in Warsaw. Finally, I would like to thank our employees for a job well done over the past year, and others for their increased interest, which is being reflected in the increased trading of Eastnine shares.”
