Beyond Green ICT

An article in the McKinsey Quarterly argues that ICT can enable enough energy efficiency and carbon reduction to more than offset ICT's growth. "An analysis of five groups of abatement opportunities finds that such technologies could help to eliminate 7.8 metric gigatons of greenhouse gas emissions annually by 2020 [chart to right]—equivalent to 15 percent of global emissions today and five times more than our estimate of the emissions from these technologies in 2020." The authors base this on ICT's application to the broader economy, projecting that the gains of internal deployment (Green ICT) will be outweighed by ICT's overall global growth.
