Synergistic Pathways and Potential Assessment for Pollution and Carbon Reduction in Typical Coastal Cities: A Case Study of Haishu District Ningbo

Year: 2025

Type: article

Abstract: Under the “dual carbon” strategy, achieving synergy between pollution reduction and carbon mitigation is crucial for the sustainable development of coastal cities. However, existing studies frequently emphasize single-carbon reduction measures whilst neglecting to acknowledge the cross-sectoral synergistic effects. This study takes the Haishu District of Ningbo in Zhejiang Province as a case study and quantitatively assesses the effectiveness of synergistic governance strategies across four key pathways: photovoltaic power generation, carbon sequestration by green land, new energy transportation, and waste incineration for power generation. The results demonstrate that multi-sectoral coordinated management significantly enhances overall emission reduction efficiency, with the photovoltaic and waste-to-energy pathways showing the highest carbon reduction potential. This study establishes a multi-pathway framework for evaluating the synergistic effects of pollution and carbon reduction. It also provides scientific support for decision-making regarding the transition to a low-carbon economy in coastal cities, and proposes a replicable evaluation methodology that can be used to implement dual carbon strategies in other coastal regions.
