Le contenu d\u00e9crit la demande adress\u00e9e le 14 septembre 2026 par le Premier ministre au Conseil \u00e9conomique, social et environnemental (CESE) afin de mener une r\u00e9flexion de long terme sur l\u2019adaptation de la France au changement climatique, en compl\u00e9ment des mesures gouvernementales visant \u00e0 acc\u00e9l\u00e9rer la mise en \u0153uvre du troisi\u00e8me Plan national d\u2019adaptation au changement climatique (PNACC\u20113), publi\u00e9 en mars 2025. Ce plan s\u2019appuie sur une trajectoire de r\u00e9f\u00e9rence correspondant \u00e0 un r\u00e9chauffement moyen de 4 \u00b0C en France hexagonale \u00e0 l\u2019horizon 2100 par rapport \u00e0 l\u2019\u00e8re pr\u00e9industrielle, utilis\u00e9e pour anticiper les conditions climatiques auxquelles devront r\u00e9sister les b\u00e2timents, les infrastructures et les activit\u00e9s \u00e9conomiques.<\/p>\n
L\u2019adaptation est pr\u00e9sent\u00e9e comme une d\u00e9marche visant \u00e0 pr\u00e9parer les activit\u00e9s et les territoires aux effets d\u00e9j\u00e0 perceptibles du changement climatique sur la vie quotidienne, tels que les difficult\u00e9s \u00e0 rafra\u00eechir les logements lors des canicules, les s\u00e9cheresses affectant les exploitations agricoles ou les perturbations des r\u00e9seaux de transport lors d\u2019\u00e9v\u00e9nements extr\u00eames. Elle recouvre notamment l\u2019am\u00e9lioration du confort d\u2019\u00e9t\u00e9 des b\u00e2timents, l\u2019adaptation des pratiques agricoles ou la r\u00e9vision de l\u2019am\u00e9nagement des zones expos\u00e9es aux inondations. Elle est explicitement d\u00e9crite comme compl\u00e9mentaire \u00e0 la r\u00e9duction des \u00e9missions de gaz \u00e0 effet de serre, qui agit sur les causes du r\u00e9chauffement.<\/p>\n
La saisine du Premier ministre invite le CESE \u00e0 examiner les conditions de cette adaptation en tenant compte de la situation \u00e9conomique et des contraintes budg\u00e9taires. Elle porte sur dix questions, organis\u00e9es autour de deux axes principaux. D\u2019une part, la r\u00e9partition des responsabilit\u00e9s entre l\u2019\u00c9tat, les collectivit\u00e9s territoriales, les acteurs \u00e9conomiques et les citoyens, incluant la prise en charge de l\u2019anticipation et des cons\u00e9quences des \u00e9v\u00e9nements climatiques extr\u00eames. D\u2019autre part, le financement de l\u2019adaptation, avec une \u00e9valuation des besoins \u00e0 moyen et long terme, en distinguant les d\u00e9penses d\u2019investissement et de fonctionnement, et en les mettant en regard des dommages climatiques \u00e9vit\u00e9s.<\/p>\n
Les travaux annonc\u00e9s doivent analyser les modalit\u00e9s de mobilisation des financements priv\u00e9s pour la pr\u00e9vention, l\u2019investissement et la gestion des cons\u00e9quences des \u00e9v\u00e9nements climatiques, ainsi que les m\u00e9canismes de solidarit\u00e9 territoriale et les conditions d\u2019intervention des financements publics. Les enjeux identifi\u00e9s sont de long terme, les d\u00e9cisions \u00e0 prendre ayant des effets qui se prolongeront sur plusieurs d\u00e9cennies, et doivent int\u00e9grer les in\u00e9galit\u00e9s d\u2019exposition aux risques climatiques entre populations et territoires. Les formations de travail mentionn\u00e9es renvoient aux commissions Environnement, Am\u00e9nagement du territoire, Activit\u00e9s \u00e9conomiques, \u00c9conomie et finances du CESE, sans pr\u00e9cision suppl\u00e9mentaire sur leurs travaux propres.\u00a0(contenu r\u00e9sum\u00e9 par l’IA)\u200bLire la Suite<\/a>\u200b<\/p>","protected":false},"excerpt":{"rendered":" Le contenu
