Cloud computing could prevent the emission of more than 1 billion metric tons of carbon dioxide (CO2) from 2021 through 2024, a forecast from IDC shows. The emissions reductions are driven by the aggregation of computation from discrete enterprise datacenters to larger-scale centers that can more efficiently manage power capacity, optimize cooling, leverage the most power-efficient servers. The Asia/Pacific region, which utilizes coal for much of its’ power generation, is expected to account for more than half the CO2 savings over the next four years.
