Both of them are known to be less affected by climate change than cattle, [3]: 747 with goats in particular considered one the most climate-resilient domestic animals, being second only to camels. [76] In Southeastern Ethiopia, some of the cattle pastoralists are already switching to goats and camels. [49]
Livestock operations are responsible for about 18% of greenhouse gas emissions globally and over 7% of greenhouse gas emissions in the U.S. [24] Methane is the second most concentrated greenhouse gas contributing to global climate change, [25] with livestock contributing nearly 30% of anthropogenic methane emissions. [26]
One quarter of the world's greenhouse gas emissions result from food and agriculture (data from 2019). [15] Farm animals' digestive systems can be put into two categories: monogastric and ruminant. Ruminant cattle for beef and dairy rank high in greenhouse gas emissions. In comparison, monogastric, or pigs and poultry-related foods, are lower.
Meat from cattle and sheep have the highest emissions intensity of any agricultural commodity. Greenhouse gas emissions across the supply chain for different foods. Livestock produces the majority of greenhouse gas emissions from agriculture and demands around 30% of agricultural freshwater needs, while only supplying 18% of the global calorie ...
The Food and Agriculture Organization estimates that in 2015 around 7% of global greenhouse gas emissions (GHG) were due to cattle, [note 1] but this is uncertain. [95] Another estimate is 12% of global GHG. [ 96 ]
Livestock's Long Shadow: Environmental Issues and Options is a United Nations report, released by the Food and Agriculture Organization (FAO) of the United Nations on 29 November 2006, [1] that "aims to assess the full impact of the livestock sector on environmental problems, along with potential technical and policy approaches to mitigation". [1]
In the United States, agriculture is the second largest emitter of greenhouse gases (GHG), behind the energy sector. [1] Direct GHG emissions from the agricultural sector account for 8.4% of total U.S. emissions, but the loss of soil organic carbon through soil erosion indirectly contributes to emissions as well.

The United Nations' Intergovernmental Panel on Climate Change's (IPCC) Special Report on Climate Change and Land (SRCCL), also known as the "Special Report on climate change, desertification, land degradation, sustainable land management, food security, and greenhouse gas fluxes in terrestrial ecosystems", [1] [2] is a landmark study from 2019 by 107 experts from 52 countries.
