What is GRESB and Why Does It Matter for SA Property?
GRESB (Global Real Estate Sustainability Benchmark) is the leading ESG benchmark for real estate and infrastructure assets worldwide. For South African listed property funds and REITs, a strong GRESB score is increasingly a prerequisite for attracting international institutional capital. This section will cover GRESB's role in the SA property investment landscape and why participation is no longer optional for funds seeking foreign investment.

What’s New in the 2026 Assessment
GRESB updates its scoring methodology annually. This section will detail the key changes for the 2026 cycle, including updated weighting for climate risk disclosure, enhanced requirements for Scope 3 emissions reporting, and the integration of carbon tax exposure as a scored indicator — a change with particular relevance for South African participants operating under Phase 2 of the Carbon Tax Act.
Preparing Your Submission: A Timeline
A successful GRESB submission requires months of preparation, not a last-minute scramble. This section will outline a month-by-month preparation timeline starting from Q1 2026, covering data collection across your portfolio, internal stakeholder alignment, third-party verification requirements, and quality assurance steps before the September deadline.
Data you need to collect
This subsection will cover the core data categories: energy consumption (by source), water usage, waste diversion rates, GHG emissions (Scope 1, 2, and 3), green building certifications, tenant engagement programmes, and governance policies. For SA funds, it will address Eskom-specific emission factors and how to handle load-shedding data gaps.
Common mistakes SA funds make
Drawing on GreenBDG's experience advising SA property companies, this subsection will highlight recurring errors: underreporting Scope 2 emissions, failing to account for landlord-vs-tenant energy splits, missing the validation window, and not benchmarking against regional peers before submission.
How Carbon Tax Phase 2 Affects Your GRESB Score
With GRESB now scoring carbon tax exposure as a climate risk factor, South African funds face a unique reporting challenge. This section will explain how to disclose your carbon tax liability within the GRESB framework and how proactive emissions reduction can improve both your tax position and your benchmark score simultaneously.
