Top ranking for Castellum's sustainability efforts

Castellum ranks first in the world in this year’s edition of the Global Real Estate Sustainability Benchmark (GRESB) awards. This marks the fourth consecutive year that Castellum has achieved the top-notch award.

GRESB is an international benchmarking tool which measures and evaluates sustainability activities among companies and funds in the real estate sector from an investor perspective. The rankings include assessments from three distinct viewpoints: environmental issues, social issues and governance. Over 1 000 real estate players were included in this year’s ranking activities, where Castellum won Global Sector Leadera best-in-class distinction for sustainability in the sector for office and industrial portfolios.

“We see ourselves as community-builders. With this as a springboard, our strategy is to take sustainability issues very seriously from all possible economical, ecological and social standpoints. The objective is to integrate our sustainability efforts into everything we do, and they should constitute a natural consideration in all our daily activities. This year’s GRESB ranking is proof positive that our strategy is right and that focusing on sustainability is profitable. I want to thank all employees who have contributed to this amazing result,” says Henrik Saxborn, CEO at Castellum AB.  

Castellum has environmentally certified 33 percent of its real estate portfolio. The company works actively to achieve several challenging sustainability goals, including total diversity for all professions throughout the company and 100% climate neutrality by 2030. Castellum has also fulfilled WELL-certification, the only certification system which takes the health and wellbeing of those who work in the building into account.
