17 Oct Impact of ICT on world energy consumption – and carbon footprints (Report only in French)

National Academy of Technologies of France (NATF)

EDP Sciences, 2015
The report analyses the impact of ICT’s worldwide energy consumption and greenhouse-gas emissions, considering the impacts generated by the operation of its various hardware and infrastructure, and the savings it spawns in other areas of activity. Conclusion: The final energy and carbon balance of all ICT categories together is clearly a positive one. In 2012, ICT accounted for 4.7% of worldwide electricity consumption, and a total carbon footprint of about 1.7 percent. These numbers are on an upwards trend, but in smaller proportions than the growing use of ICT, thanks to its contribution to reduce these footprints in other areas of activities such as in the transport sector, buildings, manufacturing industries, or even dematerialised procedures. The report focuses on the (global) transport/mobility sector benefitting from digitisation in and around vehicles and lists current lines of research aimed at better performance of computing, with lower energy consumption.
