Decarbonizing Urban Industrial Zones: A Multidimensional Framework for Integrating Renewable Energy, Circular Economy, and Policy Incentives

Abstract:

Urban industrial zones are major contributors to global greenhouse gas emissions and air pollution, yet they hold untapped potential for decarbonization. This study develops a multidimensional framework integrating renewable energy adoption, circular economy practices, and policy incentives through a systematic literature review (n=196) and cross-case analysis of 12 industrial zones across Europe, North America, and Africa. The findings identify three core pillars—technological integration, resource circularity, and regulatory alignment—as critical for scalable decarbonization. The framework addresses gaps in existing research by bridging technical feasibility with socioeconomic and policy realities. Practical implications for industrial stakeholders, policymakers, and urban planners emphasize cost-effective, inclusive strategies that balance emission reductions with economic resilience. This research contributes to Global Pollution Solutions discourse by providing actionable pathways to transform industrial zones into low-carbon hubs.
