Fossil fuels CH4 emissions coming from coal, oil and gas production are much higher!
Benjamin Hmiel from University of Rochester found out that fossil fuel extraction causes a much higher impact on Climate change than thought before: Hmiel and his colleagues found that apparently about ten times less methane escapes naturally from geological sources than previously assumed. Conversely, coal, oil and gas production therefore accounts for a significantly higher proportion of methane emissions. : https://www.nature.com/articles/s41586-020-1991-8.epdf
