To help you communicate your results externally, GRESB provides a range of marketing resources, including logos, press release templates, and off-the-shelf quotes, available on our website.
The 2025 GRESB Sector Leaders will be contacted in the weeks following the results release, and the aggregate public benchmark data for real estate and infrastructure will be published on October 15, coinciding with our 2025 Global Results program.
How to Read Your Benchmark Report

GRESB Events
Launching October 15: GRESB Global Results 2025
Brought to you in a brand-new format, the GRESB Global Results 2025 program, launching October 15, spotlights the fundamentals that drive performance in real assets—clarity, resilience, operational efficiency, and disciplined, data-driven strategy.
This year’s program is designed to help you see the big picture of today’s market dynamics and surface the signals that matter most for decision-making and long-term value creation. It offers an immersive experience that lets you explore the Benchmark Results and discover how members are strengthening resilience, improving efficiency, and managing risk to unlock long-term value.
The program goes beyond results to highlight themes such as rising physical risk, efficiency as a competitive edge, tenant engagement, and evolving investor priorities. The new format also streamlines access to guidance, ecosystem resources, and platform enhancements, alongside interactive dashboards for a deeper dive into your results.
For a sneak peek, watch Chris Pyke, GRESB Chief Innovation Officer, highlight the key themes shaping this year’s results in the video below.
Secure Your Spot for GRESB Regional Insights 2025
Building on the Global Results, the GRESB Regional Insights 2025 series will translate the same fundamentals—clarity, resilience, and operational efficiency—into market-specific takeaways. Each in-person event will unpack the signals behind the scores for your region, highlighting what the GRESB Benchmark indicates about local risk pressures, operational improvement momentum, and how investors in your market are responding.
Co-hosted with GRESB Partners across 30+ cities worldwide, these events will pair data briefings with practical, real-world examples—so you can benchmark locally, compare peers, and turn insights into next steps for 2026 planning.

GRESB and IIGCC Collaborate on Net-Zero Alignment for Infrastructure Assets
Earlier this month, GRESB and the Institutional Investors Group on Climate Change (IIGCC), with support from APG Asset Management, announced the launch of a pioneering approach to assessing the alignment of infrastructure assets with the Net Zero Investment Framework (NZIF) 2.0.
NZIF Infrastructure Alignment Pilot:
The project builds on the successful completion of a pilot launched in May 2025. The pilot engaged a diverse group of infrastructure companies and assets worldwide. Early insights include:
- Among respondents, 16% reported they already achieve net zero, 2% are aligning to net zero, 62% are committed to aligning to net zero, and 20% have not yet committed.
- Half of participants have set science-based emissions targets; however, 60% do not include both short- and medium-term targets
- Most participants (84%) confirmed having governance structures in place with responsibility for targets and a decarbonization plan.
- Notably, 42% already reported declining emissions consistent with their net-zero strategies
The insights and feedback gathered through the pilot will inform the final approach, which is planned to be formally integrated into the 2026 GRESB Infrastructure Standards.
Data Center Assessment Pilot Update
GRESB is pleased to share that the pilot for the new Data Center Sustainability Benchmark will launch this week.
The pilot marks an important step toward delivering sector-specific insights that will enable more informed capital allocation, risk assessment, and due diligence across digital infrastructure. Insights from the pilot will inform the development of the Data Center Assessment, scheduled to launch in 2026.
The GRESB Data Center Benchmark
Developed in partnership with Infrastructure Masons (iMasons), the benchmark is designed to provide investors and managers with trusted, comparable metrics tailored to the unique needs and operations of the fast-growing data center sector.
To underscore the importance of this initiative, Bethany Brantley, Head of Sustainability at STACK Infrastructure and Co-Chair of the GRESB Foundation’s Data Center Working Group, alongside Christine Pries, Sustainability Manager, STACK Infrastructure, GRESB Working Group Member, co-authored the recent article Building a Better Benchmark for Data Center Sustainability: The Role of Multistakeholder, Cross-Industry Engagement and Collaboration.
The article highlights how rapid global growth in data centers has outpaced existing sustainability frameworks, reinforcing the need for fit-for-purpose benchmarks that capture the sector’s unique operational realities, technical complexity, and potential to drive positive environmental and community outcomes.
Foundation Update
2025 Standards workplan
The Real Estate and Infrastructure Standards Committees have begun to endorse the first proposals for changes to the 2026 Standards, which are then brought to the Foundation Board for approval. (For a refresher on the approval process, please revisit the GRESB Foundation 2025 Roadmap.)
During its most recent meetings, the Foundation Board has unanimously supported a clear short-, mid-, and long-term roadmap for the evolution of the Real Estate Standard. This roadmap outlines the pace and extent of the transition toward performance-based scoring, with a focus on:
- Prioritizing key climate-related topics in the near term, starting with Energy and GHG emissions
- Repositioning indicators considered common practice as prerequisites
- Launching an extensive industry consultation process, beginning in Q1 2026, to gather member feedback and guide implementation
Stay tuned for more details.
Data Center Working Group
The GRESB Foundation will soon launch the Data Center Assessment pilot and host an in-person Data Center Investor (LP) Masterclass in Q4 2025. Email [email protected] to register your interest to participate in the pilot or to join the masterclass.
Principles for Governing the Standards Development Process
In May, the Change Management Working Group finalized the Principles for Governing the Standards Development Process. These governing principles provide an additional level of transparency into how the Foundation manages incremental, annual changes to the Standards.
GRESB Foundation Director Sarah Welton recently hosted a conversation with two Foundation Board members, Katie Jowett and Esther An, to discuss the importance of the Principles in driving value through the stable evolution of the Standard. Read more about the principles here.
