When a cow belches, it releases methane, around 220 pounds of it every year, into the atmosphere. When more than 1.7 billion cows and buffalo currently on the planet burp, the resulting methane, a ...
Cows burp methane and cows are visible. But countless invisible methane leaks from landfills and oil and gas wells are still left unaccounted for.
In a 2023 interview with the think tank Lowy Institute, Gates pointed out that there are two paths of solving the emission issue of cows, who “burp and fart methane to an extreme degree.”
Cows, sheep, and other ruminants digest their food by enteric fermentation, and their burps are the main source of methane emissions from land use, land-use change, and forestry. Together with methane and nitrous oxide from manure, this makes livestock the main source of greenhouse gas emissions from agriculture.
Cows, sheep and other ruminants digest their food by enteric fermentation, and their burps are the main methane emissions from land use, land-use change, and forestry: together with methane and nitrous oxide from manure, this makes livestock the main source of greenhouse gas emissions from agriculture.

In particular, burping by domesticated ruminants, such as cows or sheep, is a major contributor of methane emissions and may have a negative effect on the environment. Significant research is being done to find mitigation strategies for ruminant burping, i.e. modifying the animals' diets with Asparagopsis taxiformis (red seaweed ).
They also say that 32 percent of human-caused agriculture emissions comes from the methane release from livestock manure, farts, and burps, about 3.7 percent of all human-led greenhouse gas emissions.
The flatulence of cows is only a small portion (around one-twentieth) of cows' methane release. Cows also burp methane, due to the physiology of their digestive systems. [60] Flatulence is often blamed as a significant source of greenhouse gases, owing to the erroneous belief that the methane released by livestock is in the flatus. [61]
