— THE GRESB INFRASTRUCTURE ASSET ASSESSMENT —
The Investor-driven Global ESG Benchmark for the Infrastructure Sector
The Infrastructure Asset Assessment assesses ESG performance at the asset level for infrastructure asset operators, fund managers and investors that invest directly in infrastructure.
The Assessment offers high-quality ESG data and advanced analytical tools to benchmark ESG performance, identify areas for improvement and engage with investors.
What is the GRESB Infrastructure Asset Assessment?
The GRESB Infrastructure Asset Assessment provides the basis for systematic reporting, objective scoring and peer benchmarking of ESG management and performance of infrastructure assets around the world. Both single and multi-asset operators can participate and the process leads to deep data insights for investors, fund managers and asset operators.
The data is self-reported by Assessment participants between April 1 and July 1 each year and subjected to a multi-layer validation process after which it is scored and benchmarked. The result is high-quality data that investors and participants can use in their investment and decision-making processes.

The Assessment is structured into separate Management and Performance Components. Each Component determines an individual score, but only entities that submit both Components will receive a GRESB Score and GRESB Rating.

Assessment Process
SYSTEMATIC ASSESSMENT

1. Validation
GRESB has established a robust data validation process to underpin the accuracy and reliability of its output. It is based on a three-layer data quality control process designed to ensure submission of high quality information. The approach to validation was developed by PwC and involves third party verification by GBCI.
2. Objective Scoring
The GRESB Scoring Model is based on an automated system, which uses a technology platform designed for GRESB by a third party that specializes in data analysis software development. The scoring is completed without manual intervention after data input.
3. Peer Benchmarking
Peer comparisons that take into account country, regional, sectoral and investment type variations provide a powerful lens through which to benchmark performance. Each participant is assigned to a peer group, based on the entity’s legal structure (listed/private), sector and geographical location of assets.
