About GRESB
GRESB Real Estate Assessment Benchmark is a globally recognized benchmark for assessing the ESG performance of real estate assets. It is a voluntary, industry-led initiative that aims to provide a comprehensive framework for evaluating the sustainability performance of real estate companies, funds, and assets.
Today, the portfolios of more than 2,200 real estate companies, REITs, funds and developers – and more than 800 infrastructure funds and asset operators – participate in GRESB Assessments. This broad market coverage provides investors with ESG data and benchmarks for USD $9 trillion worth of assets under management.
The GRESB Real Estate Assessment requires an organization to submit over 300 data points for each building. The data is then used to evaluate and score the sustainability performance of the building. This score provides a systematic way to aggregate and simplify multidimensional data into something stakeholders can understand and compare. In the case of GRESB, this means reducing hundreds of variables – like climate resilience and waste management – into a synthetic, 0-to-100 score and a set of sub-scores for aspects and indicators.
The GRESB Benchmark and Score are essential tools for all stakeholders in the commercial real estate market.
- Real Estate Trusts utilize GRESB performance to attract and retain investors by showcasing their commitment to sustainability.
- Real Estate Investment Management Companies leverage GRESB scores to demonstrate their expertise, attracting additional assets to manage for large institutional investors.
- Property Management Companies use GRESB performance to highlight their dedication to ESG principles, enhancing their reputation and expanding their property management services.
