Nantes: 2 full-time agents to review the metropolis's spending in light of the climate challenge. Green budgeting, adopted nationally in 2020, was extended to municipalities with more than 3,500 inhabitants by the 2024 finance law.
Despite the efforts made, it should be difficult to draw exhaustive lessons from this second green budget. The majority of entries relating to adaptation to climate change were, for example, stamped with an “undefined” stamp. This category designates 54% of expenses and corresponds to items which could not be classified “for lack of knowledge or methodological reference”.
