“…To fulfill the dual carbon aim and prevent air pollution in China, which is an effective strategy to promote green and high-quality development, there is a concern about the synergistic reduction of pollution and carbon emissions 72 . Theoretically possible is the synergistic effect of concurrent pollution and carbon emissions reduction due to the same root, same source, same process aspect 73 , 74 . Reducing air pollution through green technology innovation while reducing carbon dioxide emissions, thus contributes to global climate change mitigation.…”

Urban green technology innovation (UGTI) is strongly tied to environmental regulations, which can successfully balance economic and environmental benefits. Selecting the panel data for 280 Chinese cities during 2006–2019, we take the energy saving and emission reduction (ESER) demonstration city policy as a quasi-natural experiment, then employ the difference-in-differences model to examine the effect and its mechanisms of ESER policy on UGTI. Empirical results show that the ESER policy can significantly promote UGTI, especially in the western region, the northern region, and cities with weak government environmental attention. At the same time, China’s ESER policy has a stronger promoting effect on UGTI in cities where environmental targets are more stringent. Mechanism analysis shows that the policy mainly promotes UGTI through two channels: increasing the proportion of science and technology expenditure in fiscal expenditure and upgrading the structure of the industry. In addition, we find that the development of UGTI has positive environmental effects by lowering carbon emissions and air pollution. The findings not only enrich the literature on environmental regulation policies and UGTI at the theoretical level, but also provide references for policymakers to specific implementation methods in further enforcing environmental regulation policies to improve UGTI.

“…Currently, the main IFA treatment technology in the provinces remains landfill which accounts for approximately 95% of the market share, and the use of plasma melting and fuel melting technology to treat IFA is not widespread . Recommending and optimizing IFA reutilization technologies for each province in China according to the characteristics and development goals of different regions is necessary. , Development goals for different regions based on sustainable development goals (SDGs) are shown in Table . Detailed basis for setting regional development goals is as follows .…”

Municipal solid waste incinerator fly ash (IFA) reutilization is energy-intensive with expenditure and secondary fly ash (Sec-FA) generation. Technology innovation and deployment are necessary for better IFA reutilization. Herein, potential benefits of technology innovation by fuel substitution, waste heat recovery and Sec-FA reuse of preferable plasma melting, fuel melting, and sintering technologies were evaluated by life cycle assessment (LCA) and life cycle costing (LCC). Results show that fuel melting and sintering could gain more environmental and economic benefits, respectively Technology innovation could bring environmental benefits and approximately 132 to 173 RMB/t IFA of economic profitability, among which waste heat recovery could gain 32–36% of economic optimization effect. A regional technology transition in China from plasma melting to fuel melting and technology innovation with waste heat and Sec-FA recovery shows GHG mitigation (0.48–0.79 Mt/yr) and economic benefits (322.21–537.02 million RMB/yr). Policy scenarios indicated that enterprise will lose approximately 360.70 RMB/t IFA if zero-subsidy is provided.

“…Environmental pollution and carbon emissions have the same root, source, and process characteristics, so PCR targets are highly consistent, with excellent synergistic effects [16]. By means of ridge linear regression, Liang et al [17] find that each 1% increase of nitrogen oxides and sulfur dioxide, CO 2 increased by 0.86%.…”

Promoting the synergy of pollution and carbon reduction (PCR), as well as accelerating high-quality economic development (HQED), are the two major tasks of China’s current economic development. Thus, it is crucial to achieve a deep integration between PCR and HQED. We first construct the indicator system of PCR and HQED, and use the entropy method to assign weights to the indicator system. The coupling coordination model often portrays the level of coordinated development between systems. We apply this model to measure the synergistic relationship between PCR and HQED in 108 cities of the Yangtze River Economic Belt (YREB) in China from 2006 to 2021.We further analyze its spatial-temporal characteristics, regional differences, and convergence. The results reveal that the coupling coordination degree (CCD) between PCR and HQED in the YREB increases from 0.4234 in 2006 to 0.5832 in 2021. A higher CCD reflects a better coordinated developmental relationship between the two subsystems, and the relationship between the PCR and HQED shifts from on the verge of being uncoordinated to barely coordinated. Meanwhile, the CCD of the YREB shows a trend of decreasing downstream, midstream, and upstream, with significant spatial positive autocorrelation characteristics. Moreover, the overall differences in the CCD of the YREB from 2006 to 2021 show a fluctuating trend, with larger contributions of inter-regional differences and intra-regional differences. The convergence model reflects whether there is a tendency for the coupling coordination differences to narrow. Finally, the model indicates that there is no σ convergence but exists β convergence in the CCD of the YREB. Convergence is fastest in the downstream, followed by the midstream, and slowest in the upstream. The study reveals that the CCD of the YREB is increasing and has significant positive spatial correlation characteristics. It could utilize inter-city synergies, implement integrated strategies, and promote synergies between PCR and HQED in accordance with local conditions. Our findings provide empirical evidence and policy references for effectively promoting the deep integration of PCR with HQED.
