Livestock Industry Greenhouse Emissions

Livestock supply chains emitted an estimated total of 8 1 gigatonnes co 2 eq in 2010 using 298 and 34 as global warming potential for n 2 o and ch 4 respectively. Gerber et al 2013.

Frank mitloehner discussed livestock s path to climate neutrality at the final session of the virtual saskatchewan pork industry symposium.

Livestock industry greenhouse emissions. Enteric fermentation from livestock amounts to 6 2 gt of co2 equivalents 4 4 of global emissions. The methane is released primarily through belching. Mitigation strategies aimed at reducing emissions of this sector are needed to limit the environmental burden from food production while ensuring a sufficient supply of food for a growing world population.

Global livestock production contributes an estimated 18 of anthropogenic greenhouse gas ghg emissions mainly in terms of methane and nitrous oxide. The next largest portion of livestock greenhouse gas emissions is from methane produced during enteric fermentation in ruminants a natural part of ruminant digestion where microbes in the first of four stomachs the rumen break down feed and produce methane as a by product. The livestock sector is a significant contributor to global human induced ghg emissions.

A university of california davis professor and air quality specialist said the public needs to recognize the contributions of livestock agriculture to the reduction of greenhouse gas emissions. Typology of livestock production system in europe. The livestock sector requires a significant amount of natural resources and is responsible for about 14 5 of total anthropogenic greenhouse gas emissions 7 1 gigatonnes of carbon dioxide equivalents for the year 2005.

Frank mitloehner discussed livestock s path to climate neutrality at the final session of the virtual saskatchewan pork industry symposium. Evaluation of the livestock sector s contribution to the eu greenhouse gas emissions ggels page 9 32 40 000 head represent only 0 1 oflaying hen farms but contain 59 of the laying hen population. A university of california davis professor and air quality specialist said the public needs to recognize the contributions of livestock agriculture to the reduction of greenhouse gas emissions.

Agriculture 9 9 percent of 2018 greenhouse gas emissions greenhouse gas emissions from agriculture come from livestock such as cows agricultural soils and rice production. Land use and forestry 11 6 percent of 2018 greenhouse gas emissions land areas can act as a sink absorbing co 2 from the atmosphere or a source of greenhouse gas emissions. In 2006 the united nations food and agricultural organization fao reported that livestock accounted for 18 of greenhouse gases making livestock emissions one of the most significant contributors to today s most serious environmental problems.
