On December 1, China Greenhouse Gas Bulletin 2022 (hereinafter referred to as the Bulletin) was released by China Meteorological Administration (CMA).

The Bulletin shows that in 2022, the concentrations of carbon dioxide, methane and nitrous oxide observed at the Waliguan Global Atmospheric Baseline Observatory were roughly comparable to the averages in the mid-latitudes of the northern hemisphere, that the carbon dioxide concentration increase relative to 2021 was roughly the same as the global increase, and that the average absolute increase over the past 10 years was lower than the global increase during the same period.

According to the Greenhouse Gas Bulletin of the World Meteorological Organization (WMO), the amounts of warming gases in the atmosphere rose at a rate more than the annual average in the past 10 years, which would drive up temperatures to a level in excess of the goals set by the Paris Agreement.

Under the framework of WMO, CMA coordinates high-precision observations of greenhouse gases (GHGs) and related trace components in China. Since the 1980s, a network of atmospheric baseline observatories consisting of one global and six regional ones has been established.

Since 2016, China has successively launched five satellites with global atmospheric carbon dioxide monitoring capabilities, which is enabling a three-dimensional (ground-air-space) integrated GHG observation.
