How Chinese Cities Cut Emissions Differently

Researchers looked at over two million company records from 2007 to 2016. They wanted to see how city level climate rules changed firm behavior. The data covers both factories and service businesses.

Factory firms tend to keep output steady. They cut electricity use from the grid but keep burning coal and oil for core processes. Because their machines are locked into fossil fuel, total emissions hardly move even when the grid gets cleaner.

Service firms behave differently. They lower carbon intensity across all major energy types. Their emissions drop in step with a greener grid, and they do not shrink production.

The findings suggest one size does not fit all. For service heavy economies, aligning grid upgrades with downstream electrification works best. For heavy industry, targeted finance is needed to break the fossil fuel habit.
