Key Takeaways from Greenbuild 2026 and the Sustainable Finance + Investing Forum

Greenbuild 2026 and the Sustainable Finance and Investing Forum brought together commercial real estate owners, lenders and insurers as sustainability shifts beyond reporting and compliance towards financial performance, risk management and long-term asset value.

Here are our takeaways:

1.   Evaluating Sustainability through a Financial Lens

Investors increasingly assess sustainability through its financial implications for underwriting, operations, insurance and investment outcomes. For example, rising energy costs pressure net operating income (NOI), municipal performance regulations introduce compliance costs and capital requirements, and climate-related damage can cause unplanned repairs and lost rent. Lower utility costs, operating efficiency, tenant retention, reduced risk exposure and marketability underpin the business case.

Measures such as LED retrofits, HVAC optimization and controls, electrification, preventive maintenance and resilience upgrades help reduce operating costs, avoid future capital expenditures, minimize downtime and protect rent. Each opportunity requires asset-specific assessment of upfront investment, expected savings, operational impacts and contribution to long-term asset performance.

2.   Asset-Level Analysis is Becoming Increasingly Important

Portfolio assessments help identify trends and hotspot risk exposures, but can mask differences in property risks, performance and investment needs. Investment decisions require asset-specific analysis because climate risk, resilience, energy performance and regulatory exposure vary by asset, as do intervention costs and benefits. Asset-level analysis helps owners prioritize actions and allocate capital for the greatest impact, supporting more informed decisions. Emerging AI applications can help investors interpret complex datasets, identify patterns and translate insights into pragmatic strategies.

3.   Investors Want Better Data, Not More Data

Sustainability investment value depends on information quality, completeness and materiality, not volume or granularity.

Investors need timely information, transparent assumptions, performance trends and clear links to financial performance. Global real estate owners and managers representing approximately EUR 1.1 tn in real estate AUM agreed on relevant climate metrics: energy consumption, greenhouse gas (GHG) emissions, decarbonization pathway alignment, capital expenditures and physical climate risk. Inconsistent definitions and methodologies still limit comparability and integration into investment decisions^[1].

The priority now is translating the metrics that matter into decision-useful insights. This entails evaluating data processes and systems to ensure the outputs are accessible for investment and risk management functions.

4.   Decarbonization Remains an Investment Priority

Despite growing attention to adaptation and resilience, decarbonization remains fundamental to long-term real estate investment. This is because transition risks, such as energy efficiency, emissions reductions and decarbonization pathway alignment continue to influence regulatory compliance, operating costs, tenant expectations and competitiveness.

Regulatory requirements are also expanding. Sixteen U.S. jurisdictions have now adopted mandatory Building Performance Standards (BPS) requiring existing buildings to meet energy or emissions performance targets, with financial penalties for non-compliance^[2]. As requirements become more stringent, owners need to translate portfolio commitments into asset-level action: prioritize energy efficiency and electrification, identify emissions reduction opportunities and assess regulatory compliance to anticipate transition risks and associated capital requirements.

5.   Climate Resilience is an Emerging Investment Priority

Climate resilience is gaining prominence in investment strategies as a commonly pursued sustainability theme^[3]. This is because physical climate risk can affect business continuity, insurance costs and operations through unplanned repairs and interrupted rental income. Resilience helps protect cash flows and value, but its business case can be harder to establish when benefits extend beyond the current hold period.

Embedding resilience into planned capital works and tenant renewals can reduce asset-level risk and deliver near-term operational benefits. Insurance savings may provide additional value, but should not underpin the business case as recognition varies by measure and insurer.

6.   Investors are Protecting Exit Value

Sustainability is entering acquisition underwriting, asset business plans and capital budgeting as climate risks increasingly inform long-term asset value and buyer interest. This means investors must look beyond the typical investment hold period when evaluating decarbonization, capital needs and physical climate risks to account for regulatory changes and future buyer expectations well before sale. Even where these risks may not materially affect an investor during their ownership, they could influence the asset’s operating costs, competitiveness and marketability for the next owner. The strongest initiatives demonstrate credible returns, protect or enhance NOI and support long-term asset value.

Importantly, the financial case may be less about a sustainability-driven valuation premium than avoiding a future brown discount. Assets that lag market expectations could face reduced buyer interest, greater due diligence scrutiny or lower valuations. Looking beyond the hold period helps anticipate liabilities, preserve liquidity and protect exit value.

Looking Ahead

To begin translating analysis into practical investment and asset management decisions, start the next investment discussion with three questions:

• Which cash flows and asset values are exposed?
• Which interventions make financial sense and can be integrated into capital plans?
• Who benefits from the investment, during the current hold period and beyond?

The answers build a business case grounded in financial performance, risk reduction and long-term value.
