Abstract (AI)
Path to zero carbon emissions Models show that to avert dangerous levels of climate change, global carbon dioxide emissions must fall to zero later this century. Most of these emissions arise from energy use. Daviset al.review what it would take to achieve decarbonization of the energy system. Some parts of the energy system are particularly difficult to decarbonize, including aviation, long-distance transport, steel and cement production, and provision of a reliable electricity supply. Current technologies and pathways show promise, but integration of now-discrete energy sectors and industrial processes is vital to achieve minimal emissions. Science, this issue p. eaas9793
Key Findings
1
Aviation, long-distance transport, steel and cement production, and reliable electricity supply are particularly difficult sectors to decarbonize.
2
Existing technologies and pathways show promise, but achieving near-zero emissions requires integrating currently separate energy sectors and industrial processes.
3
Global carbon dioxide emissions must reach zero later this century to avoid dangerous levels of climate change.
4
Most global carbon dioxide emissions originate from energy use, making energy-system decarbonization essential for climate mitigation.
