L\u2019Insee publie en octobre 2026 une analyse de l\u2019\u00e9volution de l\u2019empreinte carbone li\u00e9e \u00e0 la demande finale int\u00e9rieure en France sur la p\u00e9riode 2010-2025. Sur cette p\u00e9riode, l\u2019empreinte carbone de la France, hors \u00e9missions directes des m\u00e9nages, diminue de 23 %, alors m\u00eame que la demande finale int\u00e9rieure augmente en volume de 18 %. Le contenu carbone unitaire de la demande finale, mesur\u00e9 en kg \u00e9quivalent CO\u2082 par euro constant, recule ainsi de 35 %, ce qui met en \u00e9vidence un d\u00e9couplage entre croissance de la demande et \u00e9missions de gaz \u00e0 effet de serre.<\/p>\n
L\u2019\u00e9tude d\u00e9compose la demande finale en 64 cat\u00e9gories de biens et services. Elle montre que 85 % du d\u00e9couplage observ\u00e9 provient de la baisse du contenu carbone unitaire propre \u00e0 chaque produit, et seulement 15 % d\u2019effets de composition li\u00e9s \u00e0 la modification de la structure de la demande entre produits. Pour la majorit\u00e9 des grands produits \u00e9tudi\u00e9s (7 sur 11), l\u2019\u00e9volution en volume mesur\u00e9e par les comptes nationaux est coh\u00e9rente avec celle des quantit\u00e9s physiques, ce qui limite le risque de biais de mesure li\u00e9 au partage entre prix et volumes. Certaines cat\u00e9gories, notamment le mat\u00e9riel informatique et l\u2019automobile, font exception : les effets qualit\u00e9 y sont importants, de sorte que le d\u00e9couplage calcul\u00e9 \u00e0 partir des donn\u00e9es physiques est nettement plus faible que celui issu des comptes nationaux.<\/p>\n
L\u2019analyse distingue les produits fran\u00e7ais des produits import\u00e9s. Les produits fabriqu\u00e9s en France pr\u00e9sentent en moyenne un contenu carbone plus faible que les produits import\u00e9s. Toutefois, le rythme de d\u00e9carbonation au cours des quinze derni\u00e8res ann\u00e9es est similaire pour les deux origines. Pour les produits fran\u00e7ais, la baisse du contenu unitaire en gaz \u00e0 effet de serre r\u00e9sulte de r\u00e9ductions d\u2019\u00e9missions tout au long des cha\u00eenes de valeur, en France comme \u00e0 l\u2019\u00e9tranger, ce qui souligne l\u2019importance des \u00e9missions indirectes li\u00e9es aux intrants et aux \u00e9changes internationaux. L\u2019Insee souligne enfin que la recomposition sectorielle joue un r\u00f4le important dans la r\u00e9duction globale de l\u2019empreinte, sans en d\u00e9tailler les effets quantitatifs dans l\u2019extrait disponible.\u00a0(contenu r\u00e9sum\u00e9 par l’IA)\u200bLire la Suite<\/a>\u200b<\/p>","protected":false},"excerpt":{"rendered":" L\u2019Insee publie en octobre 2026 une analyse de l\u2019\u00e9volution de l\u2019empreinte carbone li\u00e9e \u00e0 la demande finale int\u00e9rieure en France sur la p\u00e9riode 2010-2025.
