This governance can draw on extensive local expertise, which has long been involved in energy efficiency, as well as in-house IT management within the General IT Service (SEGI (Service Général d’Informatique)). According to Laurent Debra, Deputy Director of the SEGI, «several actions have already been implemented: • rationalisation of equipment (for example, pooling the technical IT infrastructures of the University and the hospital (CHU), centralising data centres and network equipment); • increasing the useful life of terminals by extending the support warranty and adapting public procurement contracts to make them even more repairable; • targeted donations of computers in working order to schools in Africa, ensuring that they do not end up in unauthorised landfill sites; • energy-efficient data centre cooling systems (using free cooling); • data compression and deduplication systems; • virtualisation systems to optimise hardware resources.» ↑ Source of the figures in the infographic: https://infos.ademe.fr/magazine-avril-2022/faits-et-chiffres/numerique-quel-impact-environnemental Per person, this figure represents: → The same environmental impact as a 2,259 km car journey. → The equivalent electricity consumption of a 1000W radiator powered continuously for 30 days.

Felix Scholtes explains: «In addition to the institutional measures that will be stepped up, our policy will not only offer training, support and advice to users, but will also welcome and coordinate initiatives in the field. We are also aiming to provide current and future citizens with a university education that will enable them to be critically and independently autonomous in this field, and we want to encourage research in this area and in relevant related fields». ← Evolution of greenhouse gas production by digital means, on the one hand, compared with a «1.5° trajectory» (IPCC), on the other hand, which are likely to intersect around 2030.
