We can never repeat it enough: when it comes to ecological transition, it is local governments that are able to seize this challenge head-on and take concrete action. Grenoble is a very inspiring example. Nine years ago, the City committed to an ambitious climate plan. From 2005 to 2017, greenhouse gases decreased by 20% on its territory, results in line with the objectives of the Paris agreements. All you have to do is move around the city center to measure its impact: a drastic reduction in the spaces allocated to the car and, in return, the enhancement of cycle lanes and other lanes reserved for public transport, including a tram network very efficient. No wonder this capital of the Isère department was named the green capital of Europe in 2022 and that its eco-friendly mayor, Éric Piolle, signed the Covenant of Mayors for Climate and Energy! His book Grow together. Cities awaken hope is required reading for anyone who wants to understand the foundations of the action of the first environmentalist mayor of a large city in France.
