Industrial parks (IPs) contribute greatly to China's economic development while emitting lots of greenhouse gas (GHG). Establishing GHG emission inventories for IPs is essential to generate low-carbon strategies. Taking 11 IPs in Central China as objects, this study established GHG inventories including direct and indirect emissions, exploring the characteristics from the point of view of energy types and industrial sectors. We then adopted cluster analysis to classify these IPs into “3Hs”, “3Ls” and “Mixed” parks, and subsequently chose representative IPs for case study. The results show that total CO₂ emissions of the parks in 2017 were 14.47 Mt. Coal combustion from energy types and energy-intensive industries from industrial sectors were the dominant emission sources, both accounting for 80% of the total emission in 11 IPs. Reducing power export and using renewable energy are crucial to mitigate GHG emission in the IPs including large-scale thermal power plants. Cluster analysis reveals that “3Hs” and “Mixed” parks should be put in a high priority in GHG mitigation, focusing on energy-intensive industries transformation and energy structure adjustment. This study is helpful to understand GHG emission characteristics of IPs in Central China and promotes the proposal and implementation of GHG emission reduction strategies in IPs.
