GRESB Data Verification
Independent. Efficient. GRESB-aligned.
Cooltree provides independent GRESB data verification for European real estate funds, executed fully in line with GRESB-approved standards.
Why it matters
Verification is no longer optional within GRESB
Third-party ESG data verification is a measurable driver of your benchmark score and a critical signal of credibility towards institutional investors.
For many funds that margin decides the difference between a 3-star and a 4-star rating. And with regulatory pressure rising through CSRD, SFDR and the EU Taxonomy, robust ESG data is no longer only about GRESB — it is about long-term resilience.
of your total GRESB score is allocated to third-party verification of energy, GHG, water and waste data.
European real estate funds verified in the past year, across retail, office, residential and mixed-use portfolios.
Our approach
Technical rigour, without the drag on your team
Independent
We operate as a third-party verifier, fully aligned with GRESB requirements.
Structured & efficient
A clear planning phase, defined documentation requirements and transparent communication keep the trajectory smooth.
Substantive, not procedural
We do more than validate numbers. We assess data quality, consistency, coverage and methodology.
Focused on continuous improvement
Each cycle generates actionable feedback, so your reporting gets stronger year on year.
What we verify
Energy consumption
Landlord and tenant-obtained energy across the reporting period.
GHG emissions
Scope 1, 2 and relevant Scope 3 emissions, checked against energy.
Water consumption
Coverage, plausibility and year-on-year movement.
Waste data
Tonnages and disposal routes, hazardous and non-hazardous.
Our methodology aligns with internationally recognised reporting principles and GRESB verification requirements.
