The real climate and transformative impact of ICT: A critique of estimates, trends, and regulationsFreitag et al.PatternsSeptember 10, 2021In BriefWe examine peer-reviewed estimates of ICT's GHG emissions, which put ICT's share of global GHG emissions at 1.8%–2.8%, yet find the actual share could be as high as 2.1%–3.9% when adjusting for truncation of supply chain pathways. We explore the reasons why current estimates vary, provide three reasons why ICT's emissions will likely increase without intervention, and outline the changes required to policy and industry targets to keep ICT's emissions in line with the Paris Agreement.
