The Grey into Green (Szare na Zielone) funding programme aims to convert grey, sealed areas surrounding schools and kindergartens into green, unsealed areas that promote healthy recreation and environmental education. Public schools and kindergartens in Wrocław, Poland can apply for financing to redesign their courtyards and gardens and implement nature-based solutions. The programme was launched in 2009 and is managed and funded by the Municipality of Wrocław. Successful schools receive funding, training and guidance to support implementation of nature-based solutions. The program promotes local stormwater retention and management, aims to increase biodiversity and protect children from noise. It represents part of the city's efforts to adapt to climate change. Until 202, 130 schools and kindergartens have taken part in the programme and have redesigned their surrounding areas and courtyards to be more green and blue.
