China has recently revised its carbon emissions calculations, resulting in a reported halving of emissions growth from 2020 to 2025. This change, highlighted in a report by the Centre for Research on Energy and Clean Air (CREA), suggests that China’s emissions rose by 7% during this period, compared to the previously reported 14% increase.
Impact on Climate Commitments
The revision implies a downward adjustment of about 700 million metric tons of carbon dioxide emissions per year, equivalent to the annual emissions of countries like Germany or South Korea. This adjustment could enable China to meet its 2030 climate commitments even if its absolute emissions continue to rise.
China’s carbon intensity, which measures carbon dioxide emissions per unit of economic output, has been a key metric in tracking its climate goals. However, the methodology for calculating this intensity has changed, now excluding non-energy uses of fossil fuels and including industrial process emissions. This shift, particularly in the context of a declining cement industry due to a weak property sector, contributes to the appearance of reduced emissions.
Concerns About Data Accuracy
Researchers have raised concerns about potential gaps in monitoring, especially in the chemicals industry, where emissions might be under-reported due to annual reporting pressures. The report warns that changes in the definition of carbon intensity could weaken China’s climate targets and introduce uncertainty in tracking progress.
Despite these concerns, under the United Nations’ climate framework, China is allowed to use its own definitions to meet its nationally determined climate pledges. However, retrospective changes in methodology or inconsistent accounting could undermine the credibility of these commitments.
As the U.S. re-evaluates its climate ambitions, China’s climate commitments are increasingly scrutinized on the global stage. The implications of these revised metrics will likely continue to be a topic of international discussion and analysis.
