Abstract:
The recently published IPCC AR6 once again emphasized the importance of CH4 mitigation in global warming abatement.CH4 is one of the most important short-life GHGs. Since many countries committed to the new C02 emission reduction targets of carbon neutrality either by 2050 or before 2060, programs focusing on CH4 e-mission reduction have been increasing, and consequently CH4 emission reduction is becoming one of the key areas for national and global GHG mitigation and international collaboration.This paper presents CH4 emission scenarios for China based on the energy transition with the carbon neutrality target, together with mitigation technology options in other non-energy activities, by applying the IPAC model.With the two scenarios used in the modeling analysis, it is found that, with the energy transition, there will be significant CH4 emission reduction by 2050. The reason for this is the reduced use of fossil fuels in the transition, with 67% CH4 emission reduction compared with that in 2015.compared with other sectors, CH4 emission reduction in energy sector has better synergy. If more CH4 mitigation is required, then reduced demand for nature gas may be a contributor.By combining this with O3 reduction, and since NOt is a precursor of O3, by 2050 NOx emission will mainly originate from natural gas combustion in the energy transition.In the meantime, CH4 emission mitigation from non-energy sectors also bears great potential.In the low-CH4 emission scenario, CH4 emission could be reduced by 14. 94 Mt by 2050, with 58% reduction compared with 2015. © Journal of Army Medical University.
