When teleworking, the IoT, and AI reduce our carbon emissions

Can ecological transition and digital transformation go hand in hand? The carbon footprint of the digital sector is far from insignificant: 4 % of greenhouses gases at the beginning of 2021 and twice that by 2025 according to the ADEME, the French agency for ecological transition. However, although digital may be a burden on the habitability […]
