Offsetting methane emissions — An alternative to emission equivalence metrics

International Journal of Greenhouse Gas Control, 2013
It is widely recognised that defining trade-offs between greenhouse gas emissions using 'emission equivalence' based on global warming potentials (GWPs) referenced to carbon dioxide produces anomalous results when applied to methane. The short atmospheric lifetime of methane, compared to the timescales of CO2 uptake, leads to the greenhouse warming ...

Practical gas emission control during landfilling. [PDF]

, 2004
Whilst the major emphasis on landfill gas control has previously related to postcompletion of landfill cells or phases rather than that during active waste placement, increasing need for odour control has changed that pattern of ad hoc capping and gas ...

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 ...

Upscaling methane emissions from rice paddies: problems and possibilities [PDF]

, 2002
Global methane emission estimates depend highly on the models, techniques, and databases used. Since emissions cannot be measured directly at large scales, it is impossible to judge which estimate is more realistic.

Simulating the effects of grassland management and grass ensiling on methane emission from lactating cows [PDF]

, 2009
A dynamic, mechanistic model of enteric fermentation was used to investigate the effect of type and quality of grass forage, dry matter intake (DMI) and proportion of concentrates in dietary dry matter (DM) on variation in methane (CH(4)) emission from ...

Methane oxidation and emission in Lake Lugano (Southern Switzerland) : a lipid biomarker and isotopic approach [PDF]

, 2015
Methane is an important greenhouse gas in Earth's atmosphere. The sources of atmospheric methane are largely biogenic, being produced under anoxic conditions by methanogenic Archaea.

Factors Affecting Enteric Emission Methane and Predictive Models for Dairy Cows

Animals, 2023
Enteric methane emission is the main source of greenhouse gas contribution from dairy cattle. Therefore, it is essential to evaluate drivers and develop more accurate predictive models for such emissions.

Composting and Methane Emissions of Coffee By-Products [PDF]

Atmosphere, 2021
In the last 20 years, the demand for coffee production has increased detrimentally, heightening the need for production, which is currently driving the increase in land cultivation for coffee. However, this increase in production ultimately leads to the amplification of waste produced.

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
