The Ministry of Housing and Urban-Rural Development (MHURD) in China promotes rooftop greening as part of sustainable urban development. Rooftop greening involves covering rooftops with vegetation to improve air quality, reduce urban heat island effects, and provide recreational spaces. MHURD provides guidelines and support for such projects, which often include pictures showcasing successful rooftop gardens and green roofs. These images serve as examples for future projects and illustrate the benefits of green roofs.
