The Global Methane Budget
Earth System Science Data
Understanding and quantifying the global methane (CH4) budget is important
for assessing realistic pathways to mitigate climate change. Atmospheric
emissions and concentrations of CH4 continue to increase, making CH4 the
second most important human-influenced greenhouse gas in terms of climate
forcing, after carbon dioxide (CO2).
Projecting the Temporal Evolution of Methane Emissions from Oil and Gas
Many recent studies have reported methane emissions from oil and gas production
regions, often reporting results as a methane emission intensity (methane
emitted as a percentage of natural gas produced or methane produced).
Almost all of these studies have been instantaneous snapshots of methane
emissions; however, total methane emissions from a production site and
the methane emission intensity would be expected to evolve over time.
Assessment of methane emissions from the U.S. oil and gas supply chain
July 13, 2018
Methane emissions from the U.S. oil and natural gas supply chain were estimated
by using ground-based, facility-scale measurements and validated with
aircraft observations in areas accounting for ~30% of U.S. gas production.
