The GRESB 2024 benchmark covered $7 trillion in Gross Asset Value (GAV) and included 2,223 property companies, REITs, funds, and developers across 80 markets. Together, the Real Estate and Infrastructure benchmarks covered $9T. For the 2025/26 reporting cycle, 1,002 individual real estate managers submitted 2,382 assessments. In 2025, 81.5% of GRESB participants held a formal net-zero policy, up from 78.8% in 2024 and 72.4% in 2023. Meanwhile, net-zero commitments moved the other way, slipping from 59.6% in 2024 to 58.7% in 2025.
Market Signal
Participation in the 2025/26 reporting cycle, while still optional, likely increased after a series of reports concluded that ESG-compliant funds made more money. GRESB itself shared the research revealing a link between participation and financial returns. At that point, ESG stopped being treated as a minor corporate social responsibility (CSR) checkbox and became a core driver of investment strategy
Those same reports illustrated a 40-percentage-point cumulative differential over an 11-year window, equivalent to about 180 basis points per year, measured specifically on European non-listed funds. The return finding changed behavior.
However, it’s important to put the findings in context. This is an association between participation and returns, not a demonstration that reporting causes performance. Managers who participate in GRESB tend to be larger, better capitalized, and to own newer assets in better locations. Those attributes produce returns on their own.
The defensible reading is narrower and still useful. Participation marks a set of operating behaviors that correlate with durable performance, and allocators - the fund managers at pension funds, endowments, foundations, family offices, and sovereign wealth funds - treat it that way. Whether the marker is causal matters less to a sponsor than the fact that capital is screening on it.
The certification premium underneath it is real. CBRE finds that LEED-certified US offices earn a 3.7% rent premium over non-certified peers after controlling for age, size, renovation status, and location, which compresses to roughly 3% post-pandemic. JLL’s modeled rental premiums run about 7% across eight US and Canadian cities, 10% across nine Asian cities, and above 11% in London.
Those are the controlled figures. Uncontrolled comparisons yield much larger numbers because they mostly measure the fact that certified buildings are newer and better sited.
The regulatory layer sitting underneath the allocation is what makes it stick. Under the EU’s Sustainable Finance Disclosure Regulation, funds are classified into Article 8 and Article 9 categories, and an Article 9 product must show that what it holds meets the SFDR sustainable-investment test, including do-no-significant-harm. Taxonomy alignment must be disclosed; it is not itself the statutory gate.
That gate is worth understanding because it operates on the asset rather than the manager. A fund that has marketed itself into Article 9 has constrained what it can buy. An asset that cannot demonstrate it meets that test is not expensive for that fund. It is unavailable.
For a sponsor selling into European capital, that turns a reporting question into a market access question. The buyer pool for a non-aligned asset does not price it lower. It excludes the asset from consideration and never makes a bid you can see.
This same structure appears across every signal in this brief. Insurance availability, lender screens, fund mandates. Each one converts a gradient into a threshold, and thresholds do not show up in comparable sales.
Case Study
The clearest picture of where institutional capital is actually going comes from Singapore’s sovereign fund, because its transactions are public even though its balance sheet is not.
GIC does not disclose total assets under management. Third-party estimates run from roughly $800 billion to more than $1.1 trillion, and any figure in that range is an estimate only.
What is verifiable is the deployment. GIC acquired the Maximus portfolio from Apollo in December 2019, 28 assets totaling roughly 1 million square meters of pan-European logistics for about €950 million. Its xScale data center joint ventures with Equinix sat inside a global xScale portfolio of more than $8 billion across 36 facilities by January 2022, and in October 2024 it took a 37.5% share of a further joint venture with Equinix and CPP Investments of more than $15 billion.
Look at where those assets sit. Central and Northern European logistics in Austria, Belgium, Germany, the Netherlands, Poland and Slovakia, and Northern European data centers. Both are water-intensive, or water-adjacent uses in the most water-secure part of the continent.
That is not a coincidence, and it is not primarily a climate statement. A data center is a long-duration asset whose operating cost is dominated by power and cooling, and whose continuity depends on grid stability and water availability. A sovereign fund with a multi-decade horizon underwriting that asset class ends up screening for exactly what a climate framework screens for, whether or not it calls it that.
The Netherlands illustrates why that screen lands where it does. Dutch flood protection standards are set by geography and are among the most stringent anywhere. Most of North and South Holland is protected to a 1-in-10,000-year standard, with the rest of the coastline at 1-in-4,000. River areas were historically engineered to a 1-in-1,250 standard.
Since 2017, the framework has been risk-based rather than return-period based, expressed as a basic safety level of 1 in 100,000 individual risk per dike section. The country’s Climate Act targets climate neutrality by 2050, and the government estimates a 70% renewable share of electricity by 2030.
For an institutional buyer, that combination is a durable operating environment purchased at public expense. Legislation protects it, and the government funds and maintains it regardless of who owns the building.
A second reason those Northern European allocations look the way they do has nothing to do with certification. It is water.
A hyperscale data center consumes water for cooling at industrial scale, and a logistics facility depends on a stable grid and predictable ground conditions. Both uses are effectively long-dated bets that a jurisdiction will still be able to supply power and water in twenty years, on terms nobody is currently negotiating.
Northern Europe is where that bet is cheapest. Not because the assets are certified, but because the water is there, the grid is stable, and the flood defenses are legislated rather than discretionary.
An allocator with a multi-decade horizon reaches that conclusion regardless of whether it runs a climate framework, which is why the allocation pattern is more informative than the ESG language wrapped around it.
Strategic Implications
The transferable lesson is about what allocators are actually buying when they screen this way.
They are buying jurisdictional durability, not building quality. A certified building in a market with weak infrastructure and no funded adaptation plan is a good asset in a deteriorating context. The screen operates at the market level first.
The certification is a filter, not the return. At a controlled 3%-3.7% rent premium, certification does not transform an asset’s economics. What it does is keep the asset inside the set that institutional capital will consider, and that set is narrowing.
Participation is becoming a condition of access. With four in five GRESB participants holding net-zero policies, a manager without one is explaining an absence rather than presenting a strategy. That is a fundraising problem before it is an asset problem.
The screen is invisible until you are on the wrong side of it. No allocator publishes the markets it has stopped underwriting. The signal reaches a sponsor as a thinner buyer pool at exit, several years after the decision.
The practical version for a sponsor is a short list of questions to answer before committing capital to a market, not after.
Ask whether the jurisdiction has a funded, legislated adaptation program rather than a published plan. A plan is an intention. A statutory funding line is a commitment that survives a change of government.
Ask what the water position is over a twenty-year horizon, not a five-year one. Groundwater rules, allocation rights, and utility capacity change slowly, then all at once, and you can know them in advance.
Ask whether the assets you intend to build or buy can satisfy an Article 9 mandate, because that determines whether European institutional capital can bid at your exit at all.
Future Signal
Three things worth watching -
Whether the GRESB return differential survives better controls. If a study strips out size, vintage, and location and the premium holds, the case strengthens considerably. If it collapses, the participation requirement becomes a governance signal rather than a performance one, which is a different and weaker argument.
Whether water security becomes an explicit screen. It currently sits inside proprietary models. Data center and logistics allocation patterns suggest it is already binding. When it appears in published investment policy statements, whole markets reprice at once.
Whether national adaptation spending starts showing up in cross-border allocation. The Dutch standards were enacted decades ago and have been continuously funded. A market that can point to a comparable commitment has something an allocator can underwrite. Most cannot.
The pattern across all three is that institutional capital is increasingly buying the context rather than the building. That is harder for a sponsor to influence and easier to check before committing.
A fourth thing is worth watching quietly, because it runs the other way. If the GRESB differential is largely a size and vintage effect, then the participation requirement is a barrier to entry that favors incumbents. Smaller managers carry the reporting cost without the portfolio characteristics that produced the return. That is a competitive dynamic, not a climate one.
Brief 7 examined the same shift in fund flows and found allocators moving from labeled products to bespoke mandates. Brief 14 takes this down to a single asset and shows what happens when a single line item is corrected to the market.
