2028 GRESB Standards: Key Changes and Transition Support

We are pleased to share that the GRESB Foundation has published the 2028 GRESB Real Estate and Infrastructure Standards. The publication marks the culmination of more than two years of work led by the Foundation and shaped through extensive engagement with the industry.

In preparation for this significant evolution, the 2027 Standards were intentionally kept stable. For real estate, the 2027 Standard was published in November 2025 and is not subject to further changes. For infrastructure, the 2027 Standards are covered in the 2028 Standards document.

2028 GRESB Standards

• Give greater weight to measured performance and the real-world outcomes it supports, including efficiency, resilience, and long-term value creation.
• Reward both absolute performance and annualized improvement, while expanding and strengthening the ways sustainability performance can be recognized.
• Provide investors with a clearer basis for engagement, risk assessment, and investment decisions.
• Reduce reporting effort by drawing largely on data participants already provide and moving foundational management indicators to a three-yearly cadence.

The changes have been shaped through the GRESB Foundation's independent, industry-led governance. For real estate, the Foundation held a public consultation in spring 2026 and published its findings in July. For infrastructure, the approach was developed with investors, asset managers, and the Infrastructure Standards Committee. The Foundation Board and both Standards Committees have guided the work throughout.

GRESB is committed to supporting members through a managed transition over the next 18 to 24 months. The 2028 Standards use a more focused set of inputs to reduce reporting effort and draw largely on the same underlying data participants already report, but they change how that information is assessed and scored. Because the recalibrated Standards redefine and recognize sustainability leadership differently, some movement in scores and relative positions within the Benchmarks is expected. These movements will reflect the new definition of leadership, not necessarily any change in the underlying performance.

Members will receive greater visibility before the new methodology takes effect and benefit from transition support:

• Over the coming weeks and months, the GRESB team will engage directly with investor members and participants through one-to-one meetings to explain the upcoming changes and what they will mean for them in practice.
• In addition to their official 2027 results, participants will also receive indicative scores showing how they would have performed under the 2028 methodology.
• For the 2028 assessment cycle, results will also be provided under the previous methodology to help explain any changes in results as the market moves to the new Standard.

The Road to Performance resource hub in GRESB Guides will provide ongoing guidance and supporting resources throughout the transition. We will continue to update the hub as further information becomes available.

Thank you to everyone who contributed through consultation, committee work, and conversations throughout this process.

We look forward to continuing this work with the industry to support better asset and investment decisions and measurable sustainability improvement at scale across real assets.
