Its not only methane, we need to be tracking things like CFC 11 & 12 leaks ON A CONSTANT BASIS. There is still consistent production in china of this and many other banned gases.
Reporting their findings again in Nature (2019), the group showed that CFC-11 emissions in eastern mainland China were around 7,000 tonnes per year higher in 2014–2017 than in 2008–2012. While this finding did not explain the full increase in CFC-11 levels seen since 2013, at 40–60% of the global rise, it represented a very significant fraction.
Crucially, the researchers also showed that the increase occurred in a specific region, primarily the north-eastern provinces of Shandong and Hebei.
