China Revises Carbon Intensity Metric to Lower Reported Emissions

China has changed how it measures carbon intensity, resulting in a significant drop in reported CO2 emission growth from 2020 to 2025. The new metric suggests a 7% increase in emissions rather than the previously indicated 14%, creating a reporting gap of roughly 700 million tonnes of CO2 annually. This retrospective accounting shift makes it easier for China to meet its domestic climate targets and international pledges. However, the specific details of the new calculation method remain undisclosed, raising questions about the transparency of the data.

This is a classic case of changing the goalposts. If you redefine carbon intensity without publishing the methodology, the metric becomes a political tool rather than a scientific one. It separates the intent of the policy from the actual atmospheric reality.

Exactly. I am more interested in the actual coal plant capacity and grid additions. You can change the math on intensity all day, but the turbines and boilers are still there. Does this change how they report actual power sector output?

Basically, China found a way to make the numbers look better by tweaking the denominator. A 700 million tonne gap is massive, it is literally the size of Germany's entire footprint. Hard to take the 2030 pledges seriously if the baseline is shifting.

The lack of a public definition for the new metric is the biggest red flag here. Without transparency, we cannot tell if this is a legitimate correction or just a way to hit a target on paper.
