Report tracks greenhouse gas concentrations in China

Data from an observatory in Qinghai province showed that carbon dioxide concentrations in the air in China last year increased at a significantly lower rate than the average annual global increase between 2013 and 2022, the China Meteorological Administration said on Friday.

The 2022 China Greenhouse Gas Monitoring Report, released by the administration on Friday, indicated that the average carbon dioxide concentration increased last year by about 2.3 parts per million, lower than the 2.46 ppm global average increase for the past decade.

According to satellite remote sensing data, the average annual increase in China between 2013 and 2022 was 2.16 ppm.

The China Global Atmosphere Watch Baseline Observatory on Mount Waliguan in Qinghai recorded carbon dioxide concentrations of about 419 ppm last year, roughly the same as the average concentration in mid-latitude regions of the Northern hemisphere.

The 12th annual report also indicated that average methane concentrations in China rose by about 14 parts per billion last year, compared with the global average increase of 16 ppb.

The administration said it had coordinated greenhouse gas monitoring efforts in regional areas to fulfill China's commitment to reducing greenhouse gas emissions and mitigating climate change.
