Emissions from computing and ICT could be worse than previously thought

Researchers claim that previous calculations of ICT's share of global greenhouse emissions, estimated at 1.8-2.8%, likely fall short of the sector's real climate impact as they only show a partial picture. The researchers point out that some of these prior estimates do not account for the full life-cycle and supply chain of ICT products and infrastructure -- such as: the energy expended in manufacturing the products and equipment; the carbon cost associated with all of their components and the operational carbon footprint of the companies behind them; the energy consumed when using the equipment; and also their disposal after they have fulfilled their purpose.
