Abstract: By recognizing the importance of non-CO2 gases mitigation for climate change abatement, modeling study for multi-gas scenarios was conducted by using IPAC model. This is also part of EMF-21 study for comparing the cost for CO2 mitigation and multi-gas mitigation. The main objective of this analysis is to evaluate the international potential and costs of non-CO2 greenhouse gas abatement. Three scenarios were defined by EMF-21 study including modeler reference, CO2 only mitigation scenario and multi-gas mitigation scenario. By comparing the results for the three scenarios, it is found that there is quite large potential for non-CO2 mitigation potential. Multi-gas mitigation policies could have lower cost compared with CO2 only mitigation policies. In order to reach same mitigation target level of GHG emission, there could be 30% lower carbon tax rate for multi-gas mitigation, and therefore GDP loss could be reduced by 23% in 2100. Multi-gas mitigation could give less pressure for energy system to transform.
