Attribution of production-stage methane emissions to assess spatial variability in the climate intensity of US natural gas consumption

Environmental Research Letters, 2021
Although natural gas is often viewed as a commodity fuel with limited variability due to standardization for pipeline transportation, life cycle impacts of natural gas vary substantially.

Strategies Used to Reduce Methane Emissions from Ruminants: Controversies and Issues

Agriculture, 2023
Methanogenesis plays a crucial role in the digestive process of ruminant animals. During this process, methanogenic archaea produce methane as a byproduct of their metabolism.

The impact of air pollutant and methane emission controls on tropospheric ozone and radiative forcing: CTM calculations for the period 1990-2030 [PDF]

, 2004
To explore the relationship between tropospheric ozone and radiative forcing with changing emissions, we compiled two sets of global scenarios for the emissions of the ozone precursors methane (CH4), carbon monoxide (CO), non-methane volatile organic ...
