Finally, the carbon emission measurement and calculation of the industrial park needs to cover energy activities in multiple fields as much as possible within a certain area range, but at the present stage, the deficiency of the measurement and calculation methodology still exists, and carbon reduction measurement and calculation analysis cannot be performed on the carbon neutralization technology implemented by the industrial park.
