Marianna Palmour, Associate Vice Vice President | Senior Manager of ESG
GRESB (Global Real Estate Sustainability Benchmark) is the leading international standard for evaluating the ESG performance of real estate and infrastructure portfolios. Investors around the world rely on GRESB to assess how well companies manage environmental impacts, social responsibility, and governance practices across their assets. The benchmark provides a standardized, comparable, and investor-driven framework that helps organizations:
- Evaluate ESG performance through structured reporting and measurable indicators
- Benchmark progress against industry peers and global market expectations
- Identify risks and opportunities related to climate, resilience, social responsibility, and governance
- Enhance transparency for investors, regulators, and other stakeholders
- Demonstrate leadership in sustainability through third-party validation and performance scoring
By offering a consistent, data-driven lens into ESG performance, GRESB has become a critical tool for organizations seeking to strengthen their sustainability strategy, respond to investor requirements, and improve long-term asset value.
This mission aligns seamlessly with Epsten Group’s commitment to advancing sustainable, high-performing buildings and helping clients navigate ESG complexity with clarity and confidence. Our work supports GRESB’s broader goal of elevating sustainability practices across the global built environment.
