From: Structural changes and impacts of methane emissions in China
Changes in total methane emissions from China since 2000. (a) Annual variations in total methane emissions. Horizontal lines indicate the range of total emissions over the years. Error bars reflect the uncertainty associated with total emissions. Emissions before 2014 are represented by diamonds, while those after 2014 are shown as circles. The results calculated in this study are denoted by stars. (b) The trends in total methane emissions. Black line illustrates the fitted trend prior to 2019, the red line indicates the trend from 2015 to 2019, and the blue line represents the trend before 2014. Additionally, the functions of the fitting curves, along with the Pearson correlation coefficients and p-values, are provided. Total emissions are marked by black dots.
