Strategies for Reducing Ruminant Methane Emissions

Production of Methane Emissions from Ruminant Husbandry: A Review

The aim of this review is to summarize the current knowledge of methane (CH4) production from ruminants. The objectives are to identify the factors affecting CH4 production. Methane is a potent greenhouse gas (GHG). Ruminant livestock constitute worldwide the most important source of anthropogenic emissions of methane. There are two main factors influencing global warming change, an increase in...

Strategies for Reducing Enteric Methane Emissions in Forage-based Beef Production Systems

On strategies for reducing greenhouse gas emissions.

Equity is of fundamental concern in the quest for international cooperation to stabilize greenhouse gas concentrations by the reduction of emissions. By modeling the carbon cycle, we estimate the global CO(2) emissions that would be required to stabilize the atmospheric concentration of CO(2) at levels ranging from 450 to 1,000 ppm. These are compared, on both an absolute and a per-capita basis...

Potential for Reducing Global Methane Emissions From Landfills, 2000-2030

Global generation of municipal solid waste (MSW) is now ~1200 Tg/yr (1 Tg = 10 g), >70% of which is landfilled. Landfilling of waste contributes ~30-35 Tg methane (CH4 )annually to the world's total CH4 emission of ~550 Tg/yr. Recycling and thermal treatment of waste in wasteto-energy (WtE) facilities contribute equally to diverting MSW from the waste stream destined for landfills and to mitiga...

Reducing methane emissions in ruminants: is it an achievable goal?

Decreasing methane emissions and, more generally, decreasing the environmental footprint of ruminants is one pressing challenge facing the ruminant production sector. Notwithstanding, because of the intricate relationships existing between the efficiency of feed fermentation in the rumen and methanogenesis, mitigation options have to be evaluated not just in terms of their effect on methane or ...
