International Green Roof Association (IGRA)

The International Green Roof Association (IGRA) is a global organization that promotes green roofs—roofs that are partially or completely covered with vegetation. These roofs provide various benefits, including improved air quality, reduced urban heat, and enhanced biodiversity. IGRA supports the development of green roof technology, shares research and best practices, and connects professionals, companies, and communities involved in green roofing. By fostering collaboration and education, IGRA aims to increase the adoption of green roofs worldwide, contributing to sustainable urban development and environmental conservation.
