The contribution of greenhouse gas (GHG) emissions from ruminant production systems
varies between countries and between regions within individual countries. The appropriate …

Methane, both enteric and from manure management, is the most important greenhouse gas
from ruminant livestock, and its mitigation can deliver substantial decreases in the carbon …

Enteric fermentation and manure methane emissions from livestock are major
anthropogenic greenhouse gas emissions. In general, direct measurements of farm-scale …

This study investigated whole-farm methane emissions from five Danish pig farms with
different manure management practices and compared measured emission rates to …

In Denmark, agriculture is the largest source of anthropogenic methane emissions (81%),
mainly from cattle (dairy and beef) farms. Whole-farm methane emissions were quantified at …

Recent advances in satellite observations of methane provide increased opportunities for
inverse modeling. However, challenges exist in the satellite observation optimization and …

Performance and environ-economic impacts were compared for anaerobic digestion (AD) of
dairy manure and cucumber residues from liquid to solid state. Environ-economic evaluation …

Methane (CH4) emissions from oil and gas activities are large and poorly quantified, with
onshore studies showing systematic inventory underestimates. We present aircraft …

Anaerobic co-digestion is widely adopted to enhance process efficacy by balancing the C/N
ratio of the feedstock while converting organic wastes to biomethane. Goat manure (GM) …

Dairy concentrated animal feeding operations (CAFOs) are significant sources of methane
(CH 4) and ammonia (NH 3) emissions in the San Joaquin Valley, California. Optical …
