The specialty of the 22nd of April 2016 lies not simply in the fact that it is the Earth Day, but also because leaders from over 170 countries will officially sign the Paris Climate Agreement today. Going environmental friendly is consistently harped on as climate change is a burning issue at present. Though there is sufficient awareness created regarding animal cruelty issues in order to address environmental conservation there is sparse concern given to livestock in the context of global warming and climate change.

Meat Industry & GHG Emissions

Climate change is largely caused by carbon dioxide, methane, and nitrous oxide emissions, while raising animals for food is a significant contributor to these emissions. It is important to note that the environmental impact of the lifecycle and supply chain of animals raised for food, accounts for at least “51 percent of annual worldwide GHG emissions” according to a report by the United Nations Food and Agriculture Organization (UNFAO).

Methane emissions are observed to be caused mostly due to natural digestive process of animals (enteric fermentation) and manure management in livestock operations. Nitrous oxide emissions are also associated with manure management as well as the application and deposition of manure, while carbon dioxide emissions from the livestock sector are related to “fossil fuel burning during production of fertilizer for feed production, the livestock production process, processing and transportation of refrigerated products.”

Consequently, animal agriculture is responsible for about 9 percent of human-caused carbon dioxide emissions, 37 percent of human induced methane and about 65 percent of human nitrous oxide emissions, globally.” Furthermore, livestock are a major source of deforestation, desertification, as well as the release of carbon from cultivated soils.
