Mitigation of China's carbon neutrality to global warming

Projecting mitigations of carbon neutrality from individual countries in relation to future global warming is of great importance for depicting national climate responsibility but is poorly quantified. This study uses the NCAR Community Earth System Model (CESM) to project the mitigation of China's carbon neutrality (CNCN) to global warming. The results show that China's carbon neutrality can individually mitigate global warming significantly in the long term under high emission scenarios, but the impact is less significant in the near and mid-terms and under lower emission scenarios. The incorporation of CH₄ and N₂O emission changes further enhances the mitigation effect, particularly in the long term. Regional variations in the effects of CNCN are also observed.
