GRESB (formerly Global Real Estate Sustainability Benchmark) is an internationally recognised benchmark for assessing the Environmental, Social and Governance (ESG) performance of property. The annual GRESB Assessment provides the basis for systematic reporting, objective scoring and peer benchmarking of ESG management and performance in infrastructure assets worldwide.
Twelve categories are covered, including health & safety, energy, greenhouse gas emissions air pollution water waste, and biodiversity & habitat.
BAM FM collects and reports its own data each year which is subjected to a validation process before it is scored and benchmarked. BAM FM has achieved year-on-year improvement for its two PFI contract scores over the last three years.
