Solutions journalism is news about how communities and organizations are responding to social and environmental problems. The stories in this collection show how green roofs are being implemented around the world and detail their effectiveness. Eleven European cities are collaborating to implement green roofs in order to improve public health. This includes Rotterdam, a city in the Netherlands, which is utilizing green roofs as a tool to capture rainwater and prevent flooding. San Francisco has required 15-30% of new construction to have green roofs, and similar requirements have been approved in Denver and Portland, OR. Meanwhile, Tokyo focuses on using green roofs as a source for food in crowded urban areas.
