Mitigation strategies aimed at reducing emissions of this sector are needed to limit the environmental. In light of this report claiming that livestock emissions account for 51 of greenhouse gases it is clear that the government needs to address farming in its efforts to reduce greenhouse emissions.

The livestock sector is a significant contributor to global human induced ghg emissions.
Livestock emissions. Livestock represents the most important cause of ghg from agriculture contributing approximately to 80 of these emissions and more than 25 of global ghg emissions. Using a different sectoral assignment of emissions the ipcc intergovernmental panel on climate change has estimated that agriculture including not only livestock but also food crop biofuel and other production accounted for about 10 to 12 percent of global anthropogenic greenhouse gas emissions expressed as 100 year carbon dioxide. For livestock production systems nitrous oxide methane and carbon dioxide emissions are losses of nitrogen energy and organic matter that undermine efficiency and productivity.
Direct livestock emissions account for around 10 per cent of australia s greenhouse gas emissions. 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. 5 estimated the total emissions from livestock were in the range of 5 6 7 5 gtco 2 eq year 5 6 to 7 5 10 12 kg co 2 eq between 1995 and 2005.

Possible interventions to reduce emissions are therefore to a large extent based on technologies and practices that improve production efficiency at animal and herd. Methane and nitrous oxide are significant greenhouse gases as they have much greater global warming potential than carbon dioxide.
Gerber et al 2013. How to drive production smash livestock emissions 3 weeks 6 days ago new research. 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.
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. Hopefully the government will address this issue and in doing so make changes that both improve the environment and the welfare of livestock animals. 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.
Reducing methane and nitrous oxide emissions from livestock will help reduce australia s overall greenhouse gas. Methane ch 4 accounts for about 50 percent of the total nitrous oxide n 2 o and carbon dioxide co 2 represent almost equal shares with.
