Slowdown in China's methane emission growth.

ABSTRACT: The unprecedented surge in global methane levels has raised global concerns in recent years, casting a spotlight on China as a pivotal emitter. China has taken several actions to curb the methane emissions, but their effects remain unclear. Here, we developed the Global ObservatioN-based system for monitoring Greenhouse GAses for methane (GONGGA-CH₄) and assimilate GOSAT XCH₄ observations to assess changes in China's methane emissions. We find the average rate of increase in China's methane emissions (0.1 ± 0.3 Tg CH₄ yr^-2) during 2016-2021 slowed down compared to the preceding years (2011-2015) (0.9 ± 0.5 Tg CH₄ yr^-2), in contrast to the concurrent acceleration of global methane emissions. As a result, the contribution of C
