Global fossil COâ‚‚ emissions projections by sector 2010-2050
Global fossil fuel carbon dioxide emissions were around ** billion metric tons (GtCOâ‚‚) in 2023. Under current policy settings, global fossil COâ‚‚ emissions are expected to peak in the coming years, and fall to **** GtCOâ‚‚ by 2030. The electricity and heat sector is projected to experience emissions reductions of ** percent between 2023 and 2050, while those from the industry sector would remain stable over this period.Â
