Agricultural methane emissions and the potential formitigation [PDF]

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2021
Agriculture is the largest anthropogenic source of methane (CH4), emitting 145 Tg CH4 y−1to the atmosphere in 2017. The main sources are enteric fermentation, manure management, rice cultivation and residue burning. There is significant potential to reduce CH4from these sources, with bottom-up mitigation potentials of approximately 10.6, 10, 2 and 1 Tg

Computational Fluid Dynamics-Based Modeling of Methane Flows Around Oil and Gas Equipment

Atmosphere
Recent studies estimate that emissions from oil and gas production facilities contribute between 20 and 50% of the total methane (CH4) emitted in the US; therefore, quantifying and reducing these emissions are crucial for achieving climate goals. Methane

Avoiding methane emission rate underestimates when using the divergence method

Environmental Research Letters, 2023
Methane is a powerful greenhouse gas, and a primary target for mitigating climate change in the short-term future due to its relatively short atmospheric lifetime and greater ability to trap heat in Earth’s atmosphere compared to carbon dioxide. Top-down

Global distribution of methane emissions, emission trends, and OH concentrations and trends inferred from an inversion of GOSAT satellite data for 2010–2015

Atmospheric Chemistry and Physics, 2019
. We use 2010–2015 observations of atmospheric methane columns from the GOSAT satellite instrument in a global inverse analysis to improve estimates of methane emissions and their trends over the period, as well as the global concentration of ...

Temporal variability largely explains top-down/bottom-up difference in methane emission estimates from a natural gas production region

Proceedings of the National Academy of Sciences of the United States of America, 2018
Significance Our results demonstrate that access to high-resolution spatiotemporal activity data and multiscale, contemporaneous measurements is critical to understanding oil- and gas-related methane emissions.

Estimating Total Methane Emissions from the Denver-Julesburg Basin Using Bottom-Up Approaches

Gases
Methane is a powerful greenhouse gas with a 25 times higher 100-year warming potential than carbon dioxide and is a target for mitigation to achieve climate goals. To control and curb methane emissions, estimates are required from the sources and sectors
