How energy service companies moderate the impact of industrialization and urbanization on carbon emissions in China?

Energy service companies (ESCOs) have emerged to carry out energy efficiency retrofit projects, playing an essential role in mitigating carbon dioxide (CO) emissions in China. However, it remains unclear how exactly ESCOs contribute to CO mitigation during urbanization and industrialization. We conducted regression analyses on data collected in 29 provinces in China as the first case study to investigate the moderating effect of ESCOs in relationships between urbanization, industrialization, and CO emissions. The results indicate that urbanization had a significantly negative influence on CO emissions. In contrast, industrialization displayed a statistically significant positive impact on CO emissions. ESCOs have a significant moderating effect on the relationship between industrialization, urbanization, and CO emissions. The analysis also revealed that ESCOs have a better performance in areas with lower industrialization and greater urbanization. ESCOs may invest more in regions with limited ESCO activities and huge CO emission reduction demand, while energy-saving technology innovation should be advocated in regions with sufficient ESCO activities.
