Why ESG and the Central Importance of GRESB

In a world increasingly shaped by environmental, social responsibility, and governance (ESG) concerns, it becomes crucial for companies to showcase and assess their sustainability efforts. But what exactly does ESG mean, and how is performance in this area measured?

A significant evaluation method for companies is the Global Real Estate Sustainability Benchmark (GRESB), which serves as a guidepost for ESG performance. GRESB is an assessment methodology that scrutinizes sustainability performance for companies and funds in the real estate and infrastructure sectors. It focuses on environmental, social responsibility, and governance (ESG) and evaluates how well companies perform in these areas. GRESB stands out as it is specifically tailored to the needs of the real estate and infrastructure sectors, providing clear criteria and benchmarks for comparability. Compared to other assessment methods, GRESB offers a standardized and comprehensive approach to ESG, enabling investors and companies to effectively measure, compare, and enhance sustainability performance.
