Rethinking the Low-carbon Transformation of Resource-based Cities Under Net-zero Emission Targets: A Case-study Analysis of Four Resource-based Cities

Abstract

Objective: Over 120 countries have set or are considering net-zero emissions or neutrality targets. Under the targets, it is necessary to rethink the low-carbon transformation path for resource-based cities, often regarded as incompetent to transition to net-zero directly. Therefore, this paper attempts to summarize the general frame for low-carbon transformation in resource-based cities. Methods: In this paper, we build a Solow growth model with carbon emission constraints to theoretically analyze the possible path of low-carbon transformation for cities. Then we analyze four typical cities in Japan, Germany, Britain, and America. Results: The results of theoretical analysis indicate that industrial structure, technological innovation, and clean energy are the key factors for resource-based cities to move towards zero carbon. In addition, the case analysis results show that the authorities of the four cities adopted policies of industry structure adjustment, energy consumption structure adjustment, and urban environment management to achieve the low-carbon transition. The results further validate the conclusions of the theoretical analysis. Conclusion: Finally, we propose a general framework for resource-based urban transformation. Additionally, we suggest that urban authorities adjust their layout of emerging industries to local conditions, increase investment in low-carbon technologies (especially clean energy), and actively take the lead in environmental governance.
