Etude : prospective sur l’empreinte environnementale du numérique en France à l’horizon 2030 et 2050 réalisée par l’Arcep et l’ADEME

Le 6 mars, l’Arcep et l’Ademe ont publié le troisième volet de leur étude prospective sur l’empreinte environnementale du numérique en France à l’horizon 2030 et 2050. L’étude vise à identifier des leviers d’actions et des bonnes pratiques pour réduire l’impact environnemental du numérique en France 


Les principaux résultats 


A horizon 2030 

Selon l’étude, si rien n’est fait pour réduire l’empreinte environnementale du numérique et que les usages continuent de progresser au rythme actuel, à horizon 2030 le trafic de données serait multiplié par 6 et le nombre d’équipements serait supérieur de près de 65 % en 2030 par rapport à 2020, notamment du fait de l’essor des objets connectés. Il en résulterait des augmentations de: 

– l’empreinte carbone du numérique en France : environ + 45% (pour atteindre 25 Mt CO2eq) 

– la consommation de ressources abiotiques (métaux et minéraux) : + 14 % 

– la consommation électrique finale en phase d’usage : + 5 % (pour atteindre 54 TWh par an).

A horizon 2050 

Si rien n’est fait, à horizon 2050 l’empreinte carbone du numérique pourrait tripler par rapport à 2020. Si ce développement du numérique permet en partie de réduire d’autres impacts environnementaux dans d’autres secteurs (mobilité par exemple), les consommations qu’il engendrerait en électricité et en ressources posent de toute façon la question de leur faisabilité.

France Villes et territoires Durables, mobilisée pour un numérique utile et responsable, présentera le 6 avril au Hub des Territoires, le livrable « Pour un numérique sobre, résilient, inclusif et créatif », issu de ses groupes de travail qui ont réuni des représentants de l’Etat, des collectivités territoriales, des entreprises et des experts. L’occasion de vous partager des bonnes pratiques, retours d’expériences et solutions concrètes sur le sujet. 

About Nina

A student at Sciences Po Paris, enrolled in the Master’s program in Territorial and Urban Strategies, Nina is interested in public policies at the territorial level as well as the challenges of ecological transition.

As part of a student project during her first year of the Master’s program, she worked with the National Housing Agency (Anah) on eco-design in urban renovation. She then took a gap year to gain more professional experience, completing two internships: the first with the City of Paris, where she contributed to the implementation of the first plan to combat energy poverty, and the second with the Paris Urban Planning Agency (Apur), where she worked on the territorialization of public health.

Currently in her second year of the Master’s program, she is beginning an apprenticeship with the association France Villes et Territoires Durables.
