Fig. 4: Economic implications of the methane conversion gap.
From: Lack of harmonisation of greenhouse gases reporting standards and the methane emissions gap
a, d show the cumulative sum of the yearly total difference between cost of methane under reported and counterfactual emissions by sector (N=5380). b, e show the cumulative distribution function of the economic impact across companies and years under the GWP100and GWP20counterfactuals, respectively. c shows the number of companies in the sample by year and sector (the number of companies is the same in (a and d). f and g show the complementary cumulative distribution function (1-CDF) of earnings at risk under the GWP100and GWP20counterfactuals, respectively (N=4265). We express EAR in percentage points and therefore multiply (5) by 100. The black line show the complementary cumulative distribution function across all sectors. The dotted vertical lines at the top of the figures denote the average cost of methane (as reported) as a fraction of EBITDA.
