The dataset includes data infrastructure electricity consumption (in Terawatt-hours) and greenhouse gas emissions from data infrastructure (from software, IT and telecommunication services) in tCO2e (millions). % of world total is also included for both. Data is from 2015 to 2018. Panel a. Electricity consumption (Terawatt-hours) Panel b. Greenhouse gas emissions from data infrastructure in tCO2e (millions) Figure Note: Data were derived from environmental reports of companies accounting for 90 percent of data traffic. IT = information technology; tCO2e= tonnes of carbon dioxide equivalent.
