GRESB 2024: Preparing Your Real Estate Portfolio for Submission
GRESB benchmarking is increasingly important for institutional investors. Learn how to structure your data, avoid common submission errors, and improve your score year-on-year.
Why GRESB matters
GRESB (Global Real Estate Sustainability Benchmark) has become the standard for ESG performance measurement in real estate. Institutional investors use GRESB scores to compare portfolios and inform investment decisions. A strong GRESB score signals governance maturity and operational transparency.
Key assessment areas
GRESB evaluates portfolios across two dimensions: Management (policies, targets, stakeholder engagement) and Performance (energy, water, waste, GHG emissions). Both require structured evidence and consistent data.
Data quality is everything
GRESB validators scrutinise data coverage, methodology, and consistency. Missing data, unexplained year-on-year changes, or inconsistent boundaries can result in lower scores or validation flags. The key is having a governed dataset where every figure is traceable.
Tips for a stronger submission
- Start data collection early – don't wait until Q2
- Document your methodology clearly
- Ensure like-for-like comparisons are accurate
- Use automation to reduce manual errors
- Prepare evidence packs for validators
