China’s new carbon metric leaves Germany-sized gap in its emissions – Centre for Research on Energy and Clean Air

China has implemented a significant change in how it calculates its core climate goals, a move that effectively halves the reported growth of the country’s carbon dioxide (CO2) emissions over the last five years.

A Shift in Carbon Accounting

The revision focuses on “carbon intensity,” which is defined as the amount of CO2 produced per unit of economic output. Under this new measure, emissions growth from 2020-2025 is now reported at 7%.

This figure is exactly half of the 14% increase indicated by previous official statistics. The retrospective change creates a data gap of 700m tonnes of CO2 (MtCO2) per year.

Did You Know? The annual gap created by this accounting revision, 700m tonnes of CO2, is equivalent to the total emissions of South Korea or Germany.

Implications for Climate Targets

While China has not publicly defined the new measurement method, the shift makes its climate targets significantly easier to achieve. Previously, official statistics suggested the country would fall well short of its goals.

With the revised metric, China now appears to have come close to meeting its carbon-intensity target for the 2020-2025 period.

Expert Insight: Samantha Carter notes that this shift in accounting creates a critical divergence between reported progress and actual emissions. By changing the metric retrospectively, the stakes shift from achieving physical reductions to managing statistical alignment.

Future Outlook and Pledges

These inconsistencies in carbon accounting may alter the trajectory of China’s international climate pledges for 2030. Under the previous measurement system, meeting these pledges would have required emissions to fall.

However, using the revised measure, China could potentially meet its 2030 international pledges even if its actual emissions continue to rise.

Analysts suggest that plausible calculation methods may not be sufficient to explain the massive gap in data, leaving the exact nature of the revision unclear.

How much did the reported emissions growth change?

The reported growth in emissions from 2020-2025 dropped from a previous official statistic of 14% to a revised figure of 7%.

How does this change affect China’s 2030 pledges?

The new measure means China could meet its 2030 international climate pledges even if emissions go up, whereas the previous measure would have required them to fall.
