Achieving climate stabilization requires we fully decarbonize global industry, and reaching net zero industrial emissions by 2050–2070 is necessary to limit global warming to 2°C, as industry generated 33% of global anthropogenic emissions in 2014. This research paper outlines the technical measures and policies to boost technological deployment and make net zero industry a reality.
Cement manufacturing produces 5.6% of global CO2 emissions. This research finds that capturing 80% of cement’s process emissions (and no thermal emissions) by 2050 can make cement carbon-neutral, as natural carbonation offsets remaining emissions. If thermal fuel supply were fully decarbonized by 2050, a 53% process emissions capture rate achieves carbon-neutral cement. Higher capture rates than these would provide net negative CO2 emissions and the possibility that simply making concrete could reduce atmospheric CO2 concentrations.
