Street trees, trees in parks and open spaces, trees on private property and in green buildings... As well as expanding existing forests, we need to plant more trees in urban areas and on farmland.
Trees are extremely important in highly urbanised areas which have few natural habitats. They make our towns and cities more attractive and nature-oriented. Pollution and urban heat disproportionally affect areas with lower income residents, while green areas encourage healthy mobility and have a proven social value in terms of promoting recreation and wellbeing.
Green roofs, urban gardens, and replacing tiles with plants also help to green our cities. Although the pledge is about trees, smaller plant and grass species can be used to create other types of green areas, which bring similar benefits.
