The figure below shows the mean monthly XCO₂ concentrations at terrestrial observation points from September 2014 to December 2021, aggregated for each economy in the Asia and Pacific region, and compared with the global average of mean monthly XCO₂ concentration levels during the same period. 

 

The figure highlights that 33 of the 46 economies in Asia and the Pacific had 2014–2021 monthly mean XCO₂ concentration levels higher than the global average. Notably, all economies in the East Asia subregion had mean XCO₂ concentrations above the global average, while 90% of economies in both the Southeast Asia and Central and West Asia subregions were above the global average. 

The figure below shows the percentage and count of each economy’s observation locations (at 25 km² grids) that recorded XCO₂ concentrations above the global average across 2014–2021. The analysis reveals that, of the 46 economies with available data, 31 had a majority of locations with XCO₂ concentrations exceeding the global average. It should be noted that, at the spectrum's extremes, the economies of Hong Kong, China; Niue; and Palau as well as Maldives and the Federated States of Micronesia were represented by a single observation location. However, such analysis enables policymakers to address drivers of climate change that might be evident in or around those observation locations that exceeded the global average for XCO₂ concentrations.
