Livestock and enteric methane

Every year almost 600 million tonnes of methane are emitted in the atmosphere. Of these, about 60 percent originates from human activities. Agriculture contributes to nearly half of the global anthropogenic methane production, followed by fossil fuels and waste. The livestock sector is one of the greatest contributors of methane emissions, mainly produced through the natural digestive process of ruminants known as “enteric fermentation” and manure management practices. Methane is a highly potent greenhouse gas that increases global temperature. To limit global warming by 2030, countries should reduce methane emissions, particularly from livestock, by 30 percent. FAO supports countries to mitigate methane emissions from livestock as part of their climate actions, while improving food security and livelihoods.
Key facts
KF_1

The Intergovernmental Panel on Climate Change (IPCC) recommended that global methane emissions must be reduced by 40 to 45 percent by 2030 to limit global warming to 1.5° C this century.

KF_2

Agriculture contributes about 40 percent of anthropogenic methane emissions, mainly from livestock systems (32 percent) and rice cultivation (8 percent). 

KF_3

Research and technical development are identifying innovative solutions to cut methane emissions in the livestock sector.

KF_5

Cattle population is the largest in the world and is responsible for around 75 percent of global enteric methane emissions.

KF_4

In the livestock sector, methane is produced mostly by the digestive process of ruminants through enteric fermentation. As microbes decompose and ferment plant materials in the rumen, methane is expelled by the animal through burping.

KF_6

Technical and policy solutions aimed at improving animal nutrition, health, and genetics must be accessible to all farmers through technology, knowledge transfer, incentives and investments.

Burping livestock are a big problem for our planet. When cows and other ruminants eat, their food ferments in their gut and produces methane, which contributes to global warming.
