The paper is based on an
analysis of global methane emissions examining almost 20,000 field data measurements collected from 70 sites across Arctic, temperate and tropical regions.
Venting is particularly problematic because methane is 86 times more potent than carbon dioxide as a greenhouse gas and venting accounts for about a
third of global methane emissions.
As the chart below shows, the researchers used data from the Global Carbon Project's (GCP) 2016 Global Methane Budget to arrive at the conclusion that 12.4 percent
of global methane emissions are attributable to oil and natural gas production.
There are 5 million cattle globally, accounting for 5 %
of global methane emissions, so a 20 % reduction in emissions per cow really adds up.
