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 ESG 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’ ESG-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.

Moreover, Partners who have successfully established this API capability are designated as GRESB API Partners in our Partner Directory.

Levels of partnership
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. Separately, three tiers of paid membership are planned for our GRESB Solution Providers – with the initial launch of a standard tier in March 2025.
