[en] In order to strengthen the action of non-state actors and give credibility to climate stabilisation scenarios, the Climate Chance Association launched in 2018 a Global Observatory of Non-State Climate Action, which aims to explain the evolution of greenhouse gas emissions, by crossing national public policies, with sectoral dynamics, strategies of private actors, local public policies, and all the actions undertaken by non-state actors at the local level. In this book, we synthesize the elements of evaluation and assessment from members of the main local and subnational networks engaged in fighting climate change (Section I), we propose 13 new case studies of cities and regions analyzing the alignment of their local public policies (Section II), and finally we offer an illustrative and interactive global overview of local public policies led in 2019 through 80 short illustrations (Section III).
