Indeed, when independent researchers at Johns Hopkins University decided to get the best estimates they could by combing through the published literature, they found that in the 11 life cycle analyses they turned up, the average greenhouse gas footprint from plant-based meats was just 7 percent of beef for an equivalent amount of protein. The plant-based products were also more climate-friendly than pork or chicken — although less strikingly so, with greenhouse gas emissions just 57 percent and 37 percent, respectively, of those for the actual meats.

Similarly, the Hopkins team found that producing plant-based meats used less water: 23 percent that of beef, 11 percent that of pork, and 24 percent that of chicken for the same amount of protein. There were big savings, too, for land, with the plant-based products using 2 percent that of beef, 18 percent that of pork, and 23 percent that of chicken for a given amount of protein. The saving of land is important because, if plant-based meats end up claiming a significant market share, the surplus land could be allowed to revert to forest or other natural vegetation; these store carbon dioxide from the atmosphere and contribute to biodiversity conservation. Other studies show that plant-based milks offer similar environmental benefits over cow’s milk.

Soy milk, for example, requires just 7 percent as much land and 4 percent as much water as real milk, while emitting only 31 percent as much greenhouse gas. Oat milk needs 8 percent of the land and 8 percent of the water, while releasing just 29 percent as much greenhouse gas. Even almond milk often regarded as a poor choice because almond orchards guzzle so much fresh water—uses just 59 percent as much water as real milk.

But not all plant-based milks deliver the same nutrient punch. While soy milk provides almost the same amount of protein as cow’s milk, almond milk provides only about 20 percent as much—an important consideration for some. On a per-unit-protein basis, therefore, almond milk actually generates more greenhouse gas and uses more water than cow’s milk.

    • Huh, from what I was reading half of the habitable land on the planet is used for Ag. Of which livestock accounts for 77%. So sure, I can see feeding corn stocks to cattle instead of composting but there’s no way the ~100 Billion livestock processed each year globally are not taking a majority of grown Ag. There’s no protein or fat in stocks too, so the feed has to be comprised of many other crops as well. As far as the land goes, Cattle aren’t native in the States at least so not too sure why the land would suffer without them in these parts.

          Makes sense, except for the fact on a cellular level the stocks will predominantly contain just cellulose which is a variation of startch. So that handleds carbs yet there are many other needs from a dietary standpoint to raise a cow.

          I am not against others eating meat, I have dietary restrictions, but daily consumption or even at every meal is unreasonable in my eyes. Plenty of data demonstrating its harmful effects on the planet at the current scale. 99% of meat is from factory farms but if it were a natural population of cattle being raised on small farms nationwide, that would make things make much more sense.

              Are you seriously saying the list of reports identifying factory farms as the perfect breeding ground for zoonotic viruses and massive air and water pollution shouldn’t be considered? Its like you work for the beef industry. Even more so, back in the early 2000’s a book called The China Study demonstrated the much higher consumption rate of red meat in the west is directly associated with the higher cancer rates compared to the east. But I enjoy science while it seems you enjoy meat and don’t care at what cost.

              You know where herbivores get all of their nutrients from…plants, so plants are just as beneficial and dont require steps consuming more resources while also being the ideal breeding ground for bird and swine flu’s plus mad cow disease.

          They’re important to soil health for sure but cows that are in CAFOs (which is most of them) are not improving the soil. We should still have cows but only pastured in ways that help the soil.

              In the US, cows do generally come from smaller farms’ cow-calf operations. They are either sold directly to feedlots after weaning or moved to backgrounding operations or ranches until they’re a year old, after which they’re sold to feedlots. 77% of beeves raised to market weight are done in feedlots with more than 1000 head which is the common definition of a CAFO for cattle. So even though they come from smaller farms, they mostly go through feedlots before consumption, and feedlots are dominated by CAFOs which have the most adverse effects. I wasn’t able to find data on what portion of cows aren’t raised to market weight in a feedlot (i.e. totally grass fed from birth to slaughter), and I additionally admit that I was oversimplifying the beef lifecycle. I also don’t see how this means that we need to increase cattle production. Surely the biggest gain to be made here is to move cattle and bison production to a fully regenerative framework where they stomp a reasonable amount of manure into the ground for their whole lives, but my intuition tells me that that will result in somewhat less beef being raised because such operations require more land than the status quo. I don’t have hard data to back that up though.

      Cattle are extremely important to the health of soil. Getting rid of cattle would kill us all. We need them to keep the soil healthy.

      I think for that, the animals should actually be grazing in the fields. Industrial handling of animals probably doesnt do much for the soil at all.

            I buy all my milk and meat from a farm. The cows are in the grass all day every day.

              Then they are lucky. In the farms I’ve been to, cows and other animals were inside stables most of the time.

                I’ve seen hundreds of farms where cows live outside in the grass. You must live in a prison country.
