巴黎是複雜生態系統所組合的城市，由於環境失序，動植物種的數量已大幅下降。巴黎面臨著棲息地破碎化、氣候變化、汙染、化肥及入侵物種等威脅，巴黎綠化計畫，也隨之啟動，而這也是巴黎可持續發展戰略的主要支柱之一。在巴黎人的支持下，巴黎市民和專業團體聚集在一起，提出了95項行動，以保護綠色空間和豐富的生物多樣性。尤其，在世界上人口最密集的城市之一創造更多綠色空間。值得一提的是，政府還會頒給巴黎市民「種植執照」，授權公民提出一個計劃重建空間，並得到城市公園管理部門的幫助，選擇合適的物種並建立。

這項綠色計畫，覆蓋整座巴黎，不僅減少城市及其郊區的城市熱島效應，更改善了巴黎人民在夏季的健康狀況。如此積極推動城市綠化的行動，也導入農業生態，允許市民在屋頂打造屬於自己的花園或菜園，不僅有助於建構低碳城市，無形中也提升了市民的社區互動與公共參與感。

Continuous Greening Project

Paris is a composition of the complicated ecological system. The quantity of animal and plant species had decreased greatly due to the disorder of the environment. Threatened by the dangerous potential of the fragmentation of the habitats in Paris, the climate change, pollution, chemical fertilizer, and invasive alien species, the Greening Paris Movement was launched. This is one of the pillars of the sustainable development strategy of Paris. With the support from Parisian, the citizens and expert groups come together and proposed 95 actions that will protect the green area and the abundance of biodiversity, and create more green space for the city that ranked as one of the densely populated areas. It is worth mentioning that the government is also issuing planting license to Paris citizens, encouraging them to propose a renovation plan and give them the support from the City Park Management Department in selecting the appropriate plants. This green project covered across Paris. It not only reduced the urban heat island effects in cities and suburban area but also improved the health condition of people in Paris during the summer time. The active city greening movement introduced the agriculture ecology and allowed citizens to build up their own garden or vegetable garden on their rooftop, which not only helped the city to develop toward a low carbon city, but also invisibly improved the citizens’ interaction with the community and engagement in public affairs.
