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.”
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 ...
Over and over, we have been told that methane is a potent greenhouse gas, it contributes to global warming, and since ruminants (i.e., cattle) produce methane, they are destroying the world. ...
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.
A lactating cow produces about 322g of methane per day, [27] i.e. more than 117 kg per year through burping and exhalation, making commercially farmed cows a major (37%) [28] contributor to anthropogenic methane emissions, and hence to the greenhouse effect. 95% of this gas (wind) is emitted through burping.

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.

Cows burp methane and cows are visible. But countless invisible methane leaks from landfills and oil and gas wells are still left unaccounted for. Commentary: What's worse for the environment ...
Methane's GWP 20 of 85 means that a ton of CH 4 emitted into the atmosphere creates approximately 85 times the atmospheric warming as a ton of CO 2 over a period of 20 years. [23] On a 100-year timescale, methane's GWP 100 is in the range of 28–34. Methane emissions are important as reducing them can buy time to tackle carbon emissions. [24] [25]
