The city of Sceaux, south of Paris, has adopted a Tree Charter in 2019 to protect and expand its urban canopy, focusing on deepening knowledge of the city's trees, implementing specific commitments, and involving both individual and collective action to safeguard the green giants of Sceaux. The charter promotes planting species adapted to the local soil and climate, incentivizes residents and landowners to plant and protect trees, and offers compensation for damaged or felled trees. Comprehensive policies like Sceaux's Tree Charter are crucial for urban resilience, as urban trees provide a wide range of benefits and sustainable systems are needed to protect and fortify them in cities. Other cities are also investing in urban trees through Local Urban Forestry Action Plans to improve the urban environment and combat heat islands, highlighting the value of trees for a more livable city in the future.
