Coordinative governance for pollution and carbon emission reduction requires a strong policy system, and quantitative evaluation of existing policies can provide references for policy improvement. Utilizing the PMC index model, this paper quantitatively evaluated pollution and carbon emission policies in Jiangsu. The results showed that the overall design of pollution and carbon emission reduction policies was good, with high consistence at provincial and municipal level. The energy, industry, transportation and construction sectors have emerged as the focal areas for coordinated governance. The advantage include a broad policy scope, clear policy priorities, and comprehensive policy support. The deficiencies include singular incentive and constraint mechanisms in some cities, and a lack of content that integrates both pollution and carbon emission reduction goals. In the future, it is suggested to optimize the policy timeliness structure across different levels, strengthen carbon sequestration construction in agriculture, wetlands and oceans, improve policy incentives and constraints mechanism, and promote the deep integration of carbon reduction policies and pollution reduction policies.
