GRHC 2025 EVENT PROGRAM
In 2025, Green Roofs for Healthy Cities (GRHC) will be hosting five Regional Grey to Green Conferences. These events will take place in both established and emerging green infrastructure markets, offering localized learning opportunities and connections that reflect the unique environmental and urban challenges of each region.
Each Grey to Green Conference will spotlight cutting-edge technologies, design practices, and policy advancements that drive the adoption of green roofs, living walls, and stormwater management solutions. Attendees will have the chance to engage with industry leaders, researchers, and policymakers through dynamic workshops and inspiring keynotes. By creating opportunities for direct engagement at a local level, GRHC aims to foster practical policies and programs that result in the increased use of green roofs, walls and other forms of green infrastructure
The 2025 event program underscores GRHC’s commitment to growing the green infrastructure movement and making its benefits accessible to more communities. These regional conferences will enable deeper connections, foster collaboration, and highlight best practices that are shaping the future of sustainable urban development. Hands on Green Roof Installation and Maintenance Professional (GRIMP) training opportunities will be available prior to several Grey to Green events, and as stand alone events in several cities. Stay tuned for updates on conference locations, dates, and programming as we prepare for a transformative year in green infrastructure advocacy and education.
