Join the GRESB Partners network
The GRESB Partners Program brings together a global network of organizations committed to transparency, comparability, and continuous improvement across the real asset industry.
Whether you’re a consultant supporting participants through the GRESB Assessment, a solution provider delivering innovative tools to enhance sustainability performance, or an industry body promoting best practices, partnering with GRESB offers increased visibility and valuable access to our growing network of asset managers and investors.
Our commercial partnership categories are designed to reflect the unique roles our partners play in driving sustainability outcomes across the investment value chain. Partners benefit from enhanced market visibility, access to exclusive GRESB resources, and targeted opportunities to collaborate, influence, and lead in a rapidly evolving landscape.
GRESB Assessment Partners are experienced sustainability advisors offering comprehensive services to support participants in completing the GRESB Assessment — including sustainability data management, reporting, and advisory support. These partners work closely with fund managers, companies, and asset operators to strengthen sustainability performance and reporting. Global and Premier-tier Assessment Partners with API integrations may also support automated data reporting to the GRESB Portal, earning the additional designation of GRESB API Partner.
GRESB Solution Providers offer distinct value beyond the GRESB Assessment process. These organizations deliver specialized products or solutions aimed at improving participants’ sustainability-related performance. By deploying practical and innovative solutions, they help managers operationalize sustainability, accelerate progress, and create long-term value. This partner category reflects GRESB’s ongoing commitment to helping managers identify high-impact tools and solutions that drive measurable sustainability outcomes.
Industry Supporters are leading regional, national, and global organizations working to advance best practices across the real estate and infrastructure sectors. Through strategic collaboration, we work with these partners to shape a more sustainable future for the built environment.
Media & Research Partners amplify knowledge and insight across the real assets industry and broader sustainability landscape. By sharing perspectives, surfacing trends, and informing market dialogue, we partner with these organizations to advance transparency, awareness, and informed decision-making.
Overview of GRESB Partner Benefits
Market visibility
We actively promote our partners to our network of more than 2,200 real estate and infrastructure members, through an online Partner Directory, key resources such as benchmark reports and assessment guidance materials, and as part of our highly-publicized annual GRESB Global and Regional Insights event series.
Our Partners stand out as industry or technical experts by publishing research, company insights, articles, or client case studies on their Partner Profile page and across our GRESB Insights platform.
Collaboration & expertise
Our partners enjoy preferential networking, industry leadership, and engagement opportunities at co-hosted and/or co-branded events, both in-person and online. Partners participate in and lead key conversations alongside GRESB and industry experts during partner-hosted and/or joint webinars, podcasts, and events—amplifying their operational experience and subject matter expertise across the growing GRESB network.
GRESB Assessment Partners at the Global and Premier tiers have priority eligibility to co-host annual GRESB Regional Insights, Results, or other network events.
Exclusive access & support
As contracted GRESB Members, all of our Partners have exclusive access to our Member Success Team via the GRESB Helpdesk – with priority support for Assessment Partners at the Global and Premier levels. Additional partner resources include onboarding and training materials and videos, a primary GRESB Account Manager, and early access to GRESB reporting resources, tools, and insights when feasible.
Staying connected
GRESB Assessment Partners receive regular Partners Key Updates and join Quarterly Partners Calls with the GRESB team. These touchpoints provide timely insights into program and Assessment developments, offer exclusive deep dives into GRESB Standards and tools, and ensure partners are equipped to support GRESB Participants effectively with the Assessment.
GRESB Assessment Partners at the Global and Premier tiers are also eligible to participate in groups established to support and provide input to the Foundation.
Three tiers of paid membership are available to GRESB Assessment Partners, at the Global, Premier, or Partner levels. You can become a partner dedicated to our real estate members, infrastructure members, or both.
Three separate tiers of paid membership with distinct benefits are planned for our GRESB Solution Providers – with the initial launch of a standard tier in March 2025 and a second tier available in Fall 2025.
Industry associations, media organizations, and research institutions may join our base partner network without a paid membership. Additional opportunities for collaboration are explored on a case-by-case basis.
GRESB API Partners
The GRESB API provides a valuable resource for GRESB Members, enabling seamless reporting of Real Estate asset-level data to the GRESB Portal. GRESB Assessment Partners at the Global and Premier levels are eligible to connect to the GRESB Portal via an API (additional terms and fees required) and receive a range of benefits in addition to those applicable for Global and Premier levels of partnership.
Additional benefits of being an API Partner include coordinated technical and API product assistance, access to regular check-ins with Partners Team, access to API support documentation, and regular updates about the changes and new functionality to the API. Moreover, Partners who have successfully established this API capability are designated as GRESB API Partners in our Partner Directory.
