Heavy industry process emissions by sector in the Sustainable Development Scenario, 2019-2070

Notes

Share of heavy industry CO2 captured represents total capture in cement, steel and chemicals production as a share of the total emissions generated in those sectors. In iron and steel production the accounting of energy-related emissions differs from that of “CO2 emissions from fuel combustion” in the IEA’s World CO2 Emissions dataset, where emissions arising from the transformation of fuels in coke ovens and blast furnaces are not included, following the IPCC designation of energy transformation processes as process CO2 emissions. Process emissions in the iron and steel sector include those arising from the use of lime fluxes and from ferroalloy production. See the forthcoming IEA Iron and Steel Technology Roadmap for details.
