China’s coal-based energy structure and its large proportion of the manufacturing industry have resulted in China having the highest CO₂ emissions in the world, accounting for about one-third of the world’s total emissions. Achieving the carbon peak by 2030 and carbon neutrality by 2060, while maintaining economic development, presents a significant challenge. Industrial parks, as core units of industrial clusters, are major sites for energy consumption and CO₂ emissions. Thus, industry parks with great carbon reduction potential are crucial for China’s carbon reduction efforts. This review systematically examines the current state of the carbon emissions of industrial parks in China and analyzes the situation and challenges faced in the low-carbon transition of these parks. Then, the major pathways, technologies, and key policies for the low-carbon transition are summarized based on the current situation. This paper assists in the low-carbon development of industrial parks and promotes the proposal and implementation of carbon emission reduction strategies.
