Cows and other livestock animals are responsible for about 40% of methane emissions globally, a potent greenhouse gas. The majority of agricultural methane emissions come from ruminant meat and dairy, such as cows, goats, and sheep. In the United States, cattle are far from the largest source of greenhouse gases, including carbon dioxide and methane. Production of methane changes based on a cow’s size, diet, and time of day.
Methane, emitted when cows belch, is the second most common greenhouse gas on the planet but has a 30 times more harmful effect on the atmosphere than CO2. Burping cows are a massive contributor to methane emissions, which have reached record levels according to new research. Canadian dairy farmer Ben Loewith is among the first farmers to start genetically breeding cows to produce less methane, a potent greenhouse gas produced when cows burp. Contrary to common belief, cow belching caused by enteric fermentation contributes to methane emissions.
Cows and other ruminant animals expel methane via belching, which enters the atmosphere and begins adding heat. The Environmental Protection Agency considers cows one of the largest sources of methane production in the world. Methane produced by “cow burps” is one of the biggest sources of greenhouse gas emissions from agriculture. Researchers are studying ways to reduce methane emissions from cows, with their burping accounting for a significant portion of global greenhouse gas output.

Did you know that cow farts are a major cause of global warming? The methane released by these animals has more of an effect …
What are the biggest contributors to climate change?
Fossil fuels, including coal, oil, and gas, are the primary contributors to global climate change, accounting for over 75% of global greenhouse gas emissions and nearly 90% of all carbon dioxide emissions. These emissions trap the sun’s heat, leading to global warming and climate change. The world is currently warming faster than ever before, altering weather patterns and disrupting the natural balance, posing risks to humans and all life forms on Earth.
Most electricity is generated by burning coal, oil, or gas, which produces carbon dioxide and nitrous oxide, which trap the sun’s heat. Over a quarter of electricity comes from renewable sources like wind and solar. Manufacturing and industry also contribute to greenhouse gas emissions, with machines used in manufacturing often running on coal, oil, or gas. The manufacturing industry is one of the largest contributors to greenhouse gas emissions worldwide.

Which animal produce the most greenhouse gas?
Livestock emissions include enteric fermentation from cattle and sheep, which produces over 90% of methane. Manure, a solid waste, also produces methane and nitrous oxide, with methane emissions highest when stored in liquid systems like manure lagoons. Feed production, including manufacturing fertilizers and other farm inputs, emits carbon dioxide and nitrous oxide emissions. Additionally, transporting and processing feed contribute to emissions related to feed transportation and processing.
Why is eating beef bad for the environment?
The Center for Biological Diversity is focusing on reducing meat consumption due to its significant environmental impact, including water and land use, pollution, and greenhouse gas emissions. The meat industry, particularly in the United States, poses a significant threat to endangered species and habitats. By consuming less meat, individuals can contribute to a healthier future for wildlife, the planet, and people. Vegetarian diets high in soy and processed foods also have negative environmental impacts, such as deforestation, soil erosion, and pesticide runoff.
Meat production also has higher environmental costs than plant protein, and the majority of soybean crops are grown for animal feed, not direct human consumption. By reducing meat consumption, individuals can contribute to a healthier future for wildlife, the planet, and people.
Do cow burps cause global warming?
Livestock production, primarily cows, contributes 14. 5% of global greenhouse gas emissions, primarily in the form of methane. Scientists are hoping that small changes in cow diets can significantly reduce this significant source of climate emissions. At the University of California at Davis, 18 cows are cordoned off from others in a dairy facility as part of a series of studies aimed at reducing the climate impact of dairy and beef production.
How to stop cows burping methane?
Ermias Kebreab and Matthias Hess, researchers at the University of California, Davis, are working on a novel approach to reducing methane emissions in agriculture by editing the microbiomes of cattle. Their inspiration comes from red seaweed, which has been shown to significantly reduce cows’ methane emissions. The seaweed works by blocking enzyme A molecule, typically a protein, that causes or catalyzes a chemical change. The researchers collected various types of seaweed from Australia and studied them in vivo and in real and real cattle.
The first study showed a substantial reduction of 60 methane emissions, with some studies showing methane reductions as high as 98. The researchers hope that their new method can help reduce methane emissions in agriculture, a challenge that other sectors like energy and transportation face.

What do cows produce when they burp?
Cattle, which consume undigested foods like grasses and hays, produce methane, a powerful greenhouse gas that impacts the climate. Methane is short-lived, lasting about a decade before being broken down into carbon dioxide and water vapor. This carbon is then used by plants for photosynthesis, allowing them to grow and produce oxygen. The biogenic carbon cycle is the path of methane from cows to the atmosphere, plants, and back to cows. This cycle is in constant rotation, with methane molecules being produced, oxidized to carbon dioxide, and subsequently taken up by plants.
If methane production decreases today compared to a decade ago, less emissions will enter the atmosphere and more historical emissions will be removed. This presents a significant opportunity in the fight against global warming. The CLEAR Center and other research centers worldwide are working on solutions to reduce methane production in cattle without compromising animal health and performance.
How do cows contribute to greenhouse gases?
Beef production contributes to greenhouse gas emissions through the agricultural production process and land-use change. Cows and other ruminant animals, such as goats and sheep, emit methane, a potent greenhouse gas, as they digest grasses and plants. Methane is also emitted from manure and nitrous oxide from ruminant wastes on pastures and chemical fertilizers used on crops produced for cattle feed. Rising beef production requires increasing quantities of land, which is often created by cutting down trees, releasing carbon dioxide stored in forests.
In 2017, the U. N. Food and Agriculture Organization estimated that total annual emissions from beef production were about 3 billion tonnes of carbon dioxide equivalent in 2010, roughly on par with those of India and about 7 of total global greenhouse gas emissions that year.
Does fart have methane?
Farts smell bad because most gas passed during flatulence is odorless, but a small portion contains hydrogen sulfide, which causes it to smell like rotten eggs. This is due to the waste of microbes helping digest indigestibles. Other factors contributing to smelly farts include byproducts from meat digestion and feces present in the rectum. Some foods and drinks associated with gas include:
- Chicken breasts
- Beef
- Chicken liver

Why is my cow burping so much?
Cattle burps contribute significantly to global warming, with methane being the main greenhouse gas by-product. Manure and belching account for around 32 of farming-related methane emissions, with methane accounting for about 30 of global warming since pre-industrial times. A research and development project led by Satoshi Koike of Hokkaido University aims to reduce methane emissions from cattle by 80 by 2050.
The project involves developing a feeding management system that controls microbiome function to reduce methane production in individual cattle. Methane is produced by bacterial fermentation in bovine rumens, which converts cellulose and other carbohydrates into short-chain volatile fatty acids (VFAs).
📹 Cow burps are a climate problem. Can seaweed help?
Changing the diet of cows might help them release less methane. This episode is presented by Delta. Delta doesn’t have a say in …
So… you might be wondering how we found out about seaweed as cow feed. It started in Canada when a farmer found that seaweed actually increased milk production as well as reproduction in dairy cows. After some research, he found that the seaweed also made them less gassy. Australian researchers started using different types of seaweed until they discovered that, in lab studies, the red seaweed Asparagopsis was hypereffective at reducing methane.
Multifaceted answer: first of all: you know the delta sponsorship is harming your brand… Then there is so much complexity around the ethics of the algae. I did four presentations in my plant biotech degree about it and was in a founding team of a start up trying to grow it. The main things I am unsure about is A is this just something people are supporting to avoid the hard things. I looked at the companies investing in this and it is big dairies so they want to save their business even if it’s bad on so many levels (feed intake, exploiting and killing complex mammals, land use, zoonosis, still high CO2 emissions a.o.), B where does the bromine go after it’s done its job: atmosphere? (Would be bad because bromoform is a ozone depleting gas), the products? (Would be bad for human and animal health) or excrements? (Would be bad because we are spreading bromine on our fields where it doesn’t belong.
I disagree, even if it’s proved that the seaweed is capable of reducing the methane emissions of cows in a significant way, there are other problems like water and land use. But the biggest issue is the ethical one, specifically of raising and killing millions of animals in horrible conditions just to eat them.
Why not tackle the problems directly by not breeding billions of land animals into existence in the first places if there are viable alternatives for protein, vitamins and minerals? The proposition of fixing emissions from the animal farming industry seems like running away from the problem and trying to fix a cracked wall with a band-aid. Eat less meat, more plant-based products and let do lab grown meat do it’s thing if people want to eat something that corresponds 1-to-1 to meat from animals.
Just asking…. Are there Less animals walking around, living etc.. Now.. Or has the Planet.. apparently Suffered More Large mammals, walking around and living etc… So my question.. with all respect for any and all replies… More animals alive now or in the past?… Cheers from Southern California
The big problem is that we are digging up carbon rich material and turning them into co2. In a world where you have problems getting people onboard to fix this problem, can we please stop muddling the water with minor side issues. Get the world to stop burning fossil fuel and THEN we can worry about cows.
Yes, the Delta sponsorship for this topic especially is preposterous. But for the people being snarky about plane versus cattle emissions: know that cattle produce much more GHG emissions than all the planes in the world combined. You can poke at Vox all you want (and deservedly so), but unless you’ve stopped eating beef and dairy (and ideally all other animals, since they are produce more GHG than non-animal foods), you’re throwing rocks in a glass house.
This doesn’t solve the problem of wildlife destruction caused by cattle farming. We waste so much of our land raising cattle and growing food for them. I suggest a meat tax to really stop people’s behaviour! Do people really care if their McDonalds burger is a vegan one? They mostly care about the cost.
Cow burps/farts are not a problem!! Those cows need to be pasture raised. Now, most are being fed a terrible diet. Cows should be grass-fed not grain fed. Aside from this, meat from ruminant animals is a superfood, vegan food is just plants that don’t have highly bioavailable nutrients and they also include tons of seed oils (trash) and plant toxins that some people react negatively to (IBS, inflammation, etc). Cows are not the problem, stop with this narrative. It’s hurting more people than you think.
These YouTube comments keep reminding me why the research in these articles are SO important. Everyone keeps blaming someone else but not themselves. In the article, the solution is actually simple. Eat less cow. But commenters keep focusing on a different problem Why Delta? Well the solution again is simple. Stop flying all the time. But these comments only prove one thing. Humans are selfish and we have to keep finding a solution to their problems. We are like children. We want to have all the fun but not face any consequences. And we want all the hard problems just solved for us. Thank you Vox. Most of my interesting knowledge seems to be coming from your articles lately!!!
Researchers are exploring the use of red seaweed as a feed additive for cows to reduce their methane emissions, which contribute to climate change. Cows release up to 220 pounds of methane every year, accounting for 4% of all greenhouse gas emissions. The seaweed, which contains a compound called bromoform, suppresses the enzyme that produces methane in cows’ digestive systems. Tests in California have shown that red seaweed can reduce methane emissions by up to 82%. Other feed additives that reduce methane include fatty acids and oregano. However, there are concerns about the potential long-term effects of adding seaweed to cows’ diets, and the logistics of scaling up production and distribution. Red seaweed can be grown in the ocean, which does not require fresh water or fertilisers, and could also help combat ocean acidification. While seaweed is not a silver bullet solution, it offers a promising alternative to changing human diets to reduce beef consumption.
“Protozoa” aren’t a specific parasite, but instead refers to a category of species, that consists of unicellular organisms, that have a nucleus in their cell, instead of freely floating DNA. They are “zoa” because of their nucleus, but they aren’t animals, therefore the “proto” part. Malaria are protozoa, but so are algae.
As a supporter of climate change solutions, I always found it weird how we focus on symptoms and not causes. Since cows release methane, why are we telling customers to change their ways and not what the cow is eating. Change what the cow is consuming, keep the natural beef in the stores and support the farmers. You can’t just tell millions of people to change their ways and not go after the source of the problem.
Given all the comments about Delta, I’m surprised if people actually think that “other” people will watch this article and walk away thinking “Airlines okay”. However, if an airline didn’t sponsor this article perhaps people would not know to support methods of reducing cow emissions. So which is it? Who are you afraid of?
Late stage capitalism is almost satirical: 1. A big industry polluter (Delta Airlines) is pointing a finger at another industry polluter (Meat and Dairy) for the effects on the environment 2. Problems caused by human intervention to nature are expected to change by somehow not changing human behavior or habits but by changing in this example changing the cow and not changing human diets. 3. If seaweed were ti “fix” the issue, that would just create a “Seaweed Industry” that is just as unsustainable as all the other agricultural practices like Meat and Dairy, plus marine ecological collapse. 4. The healthcare care industry will adopt all these problems decades from now when bromoform is found to have adverse effects on humans and cows. 5. Somehow the obvious solution is never considered
When the bisons where running free in North America, didn’t casued “climate change”, when all the ruminats where running free on the planet in the areas that now are ocupied by humans didn’t casued “climate change”, climate change is a way, Solar activity and water vapor are the most potent causes for the clime to change, and there is nothing we can do about it.
Imo. In addition to feed additives to reduce methane production there are some other methods to help curb its production. While feed additives will help with dairy and fattening cattle in a feed lot there is the whole cow/calf and stocker herd out there. For the cow calf and stocker cattle their main feedstuff is pasture, therefore feed additives are not a useful solution. But what can be done is regenerative farming methods utilizing management intensive grazing. This method of management can make the he pastures into carbon sinks and off set the methane production. A story on how this can help would be nice, and show a multi tiered solution.
Ah yes, dismissing the one actual solution (worldwide veganism) right off the bat. Beautiful. The climate problem with bovine agriculture isn’t just the burps. It’s not even primarily the burps. It’s the transportation, the land waste, and the enormous single-crop agriculture that goes into farming alfalfa and other cow feed. Poor form, Vox. Poor form.
In the Indonesian archipelago seaweed farming is carried out throughout much of the long coastlines of the country mainly by smallholder farmers and currently as of 2023 Indonesia is the largest global producer of the Red seaweeds Kappaphycus and Eucheuma and production cycles are short (30-45 days ) per year,a part-time supplementary income for small farmers – about 1% is used as food but 99% of all harvested seaweed is used for the production of thickening and gelling agents for the pharmaceutical and food industries and lately Indonesia surpassed the Phillipines as the largest producer of Red Seaweed for export to Europe and the US, so the idea of feeding seaweed to the Bovine Industry might be a great Idea, the current world production to meet the demands of the Pharma and Food industries makes it too expensive for the Cattle and Dairy Farms to reduce methane worldwide
Just curious, when millions of wild buffalo/bison and whatever other herds roamed the North America before we colonized it(not to mention the rest of the world before great herds were hunted down), why didn’t all the methane effect the earth then???? And nothing mentioned on the negative effects of mass seaweed growing? Sounds like all the other answers that environmentalists have, fix one problem only to create 3 more!
I don’t understand why people are so pressed about the sponsor being Delta. Yes, they are not exactly a green company, but Air travel is a lot more efficient than people think accounting for ~3% or less of global C02 emissions. And as for people not taking trains over short haul flights, well that is on the government for prioritizing road infrastructure over public transportation for nearly a century. Not DELTA or VOX’s fault!!!!! Thank you Vox for bringing this awareness and thank you to DELTA for sponsoring news.
CO2 is part of everything life on earth does. Humans and animals exhale it and plants inhale it. So we all need it. On that base politicians invented the greatest (scam) business idea in the world: »From all the substances that may cause Global Warming let’s concentrate only on CO2. Then we have an unbeatable argument to put a price tag on practically everything our civilization uses or needs.« This is even more devilish as science does know about a connection between Warming and CO2, but even today science cannot say which caused which. Does CO2 cause warming, or does warming cause the sea to give more CO2 into the air? Bur though these question is still not answered politicians already have decided to propagate which version will bring them more political power – and also far more profit… Based on that facts hearing them now telling us »believe the science!« if they want us to believe THEIR version of truth seems absolutely cynical.
Methane (CH4) is only 0.00019% (1.9 parts per million) of the atmosphere. Both of its narrow absorption bands occur at wavelengths where H2O is already absorbing substantially. Hence, any radiation that CH4 might absorb has already been absorbed by H2O. With the concentration of water vapour in the atmosphere being between 1,000 and 20,000 times greater than CH4, the effects of CH4 are completely masked by H2O.
This is so hypocritical, food and what we eat is merely a cultural phenomenon. It is not intrinsic to human nature. They are blaming humans for their “eating habits”, when in fact it is all the big corporations whom convince us and make us addicted to these fast food chains that accelerate the demand for producing more cows to slaughter. The solution is not how to make cows burp less, but how do we stop convincing everyone that they must eat meat, how do we slowly modify their eating habits, how do we restrict and stop incentivising the consumption of meat.? Such hypocrisy, and then the sponsor of the article si Delta airlines, travel, and specially air travel is another one of the main producers of greenhouse effect gases.
Fresh pasture often contains highly digestible carbohydrates such as sugars and fructans. These are rapidly fermented in the rumen, which reduces the amount of time microbes have to produce methane. In contrast, fibrous feeds like mature hay have more complex carbohydrates that take longer to ferment, providing more time for methane-producing microbes to generate methane.
Well what about all the pollution from the cars, trucks, motorcycles, farm equipment, aircraft emissions, logging equipment and so on and now your blaming the cows Come on really. And look at all of the trees being cutt down to make farm land but if we just ate meat we wouldn’t need all this farm land and if people would learn to grow there own food this wouldn’t be a problem. We need trees to clean the air .
There seems to be something wrong with the graph at 3:31. You say that seaweed reduces emissions by 82%, yet the graph shows a reduction of more than 100%. And what is up with an airplane company sponsoring a article? And that article being about climate change? This article is a huge miss-step and a bad spot on your image, guys.
Cow burps are not a climate problem. This is a common, media induced misconception which leads to misinformation. Cows have evolved, just as humans have, to live and breath within the Earth’s atmosphere without causing a climate problem. The real problem is human overpopulation and consequently the overproduction of livestock for beef and dairy consumption. This is still not the root climate problem, it is only a supplemental problem. Industry is the real culprit.
