Here, we show that China’scarbon neutrality (CNCN) can individually mitigate global warming by 0.48 °Cand 0.40 °C, which account for 14% and 9% of the global warming over the longterm under the shared socioeconomic pathway (SSP) 3-7.0 and 5-8.5 scenarios,respectively. Further incorporating changes in CH4 and N2O emissions inassociation with CNCN together will alleviate global warming by 0.21 °C and0.32 °C for SSP1-2.6 and SSP2-4.5 over the long term, and even by 0.18 °C forSSP2-4.5 over the mid-term, but no significant impacts are shown for all SSPs inthe near term. Divergent responses in alleviated warming are seen at regionalscales. The results provide a useful reference for the global stocktake, whichassesses the collective progress towards the climate goals of the ParisAgreement.Global warming since the preindustrial era has been primarily attrib-uted to the increase in atmospheric CO2 concentrations, which mainlyresults from the carbon emissions of fossil fuel combustion1,2. Thelikely range of the total human-caused global surface temperatureincrease from 1850–1900 to 2010–2019 is 0.8 °C to 1.3 °C, with a bestestimate of 1.07 °C2. The contributions of historical anthropogeniccarbon emissions have been quantified, although the currently existingqualif...
