It's Not the Cow. It's the How.

You've probably seen the headlines. Cows are bad for the planet. Cattle are cooking the earth. Maybe you've even had someone at a dinner party tell you, with total confidence, that the burger on your plate is single-handedly melting a glacier somewhere.

I get it. It's a catchy villain. Cows are big, they're everywhere, and yes — they burp methane. That part's true. But like most things that make a good headline, the full story has a lot more nuance to it than "cows bad."

Because here's what almost nobody explains: not all beef is raised the same way, and how a cow lives changes a lot about her carbon footprint.

So let's slow down and actually look at it. Feedlot and pasture systems work very differently, and understanding those differences helps make sense of why you'll see such a wide range of numbers when people talk about "beef's carbon footprint."

How Feedlot Systems Work

Most of the beef in this country — somewhere around three out of every four steaks or burgers — spends the last few months of its life in a feedlot, or Concentrated Animal Feeding Operation (CAFO). Cattle are gathered in one place and fed a grain-heavy ration designed to add weight efficiently in a shorter window of time.

There are real tradeoffs built into that system, in both directions:
Concentrating animals concentrates their manure, too. When a lot of cattle are gathered in one place, their manure collects in lagoons or holding areas rather than being spread across land. Without oxygen, that manure breaks down anaerobically, a process that produces methane and nitrous oxide. 

• The grain has to be grown somewhere. Feedlot rations rely on large volumes of corn and soy, which in a lot of the country is grown on tilled, monocropped ground with synthetic nitrogen fertilizer. Producing that fertilizer and tilling that ground both come with their own emissions.
  
• 
• Feedlot ground doesn't build soil carbon. Bare, compacted feedlot pens and tilled row-crop ground aren't actively pulling carbon out of the air and storing it the way growing, living pasture can. Not to mention, having bare ground drastically increases soil temperature (10-30 degrees F); picture acres and acres of ground sitting barren, baking in the sun. Does the Dust Bowl ring a bell? 
  
• Put together, feedlot systems are efficient in some ways — they produce more beef on less land — while carrying emissions that are just harder to see, tucked into the grain fields, the fertilizer plants, and the manure ponds instead of the pen itself. Understanding that full picture is the first step toward understanding why the pasture side of this story looks so different.
  

How Regenerative Grazing Works

Now let's look at the pasture side — the approach our family has built our whole operation around.

Rotational grazing changes what manure does. We move our herd through paddocks the way a herd of bison once moved across the plains — grazing an area for a short burst, then moving on and letting it rest and regrow. We're working toward 50 to 60 head per acre, rotated every few hours, a practice we've talked about before as mob grazing. Manure spread across pasture in smaller amounts breaks down aerobically, with oxygen, instead of anaerobically in a lagoon. That shifts it from a methane source into fertilizer (with zero emissions) for the next round of grass. Same manure, different process, very different outcome, depending on where it lands.

That grazing pressure also builds root depth. Short, intense grazing followed by rest stimulates grass to grow deeper root systems, and deeper roots are part of how pasture pulls carbon out of the atmosphere and stores it underground.

Cover crops and no-till keep carbon where it's already stored. Sorghum, triticale, cow peas, winter rye — the mixes we plant do double duty, feeding cattle and feeding the soil. Because we're not tilling that ground, the carbon that has built up underground stays there; instead of being released back into the air like it does when a field gets plowed.

Healthy soil hosts bacteria that consume methane. This is the part that still gets me. Well-managed pasture soil supports methanotrophic bacteria — microbes that use methane as an energy source, essentially eating some of it before it reaches the atmosphere. That kind of soil biology depends on the ground being alive and undisturbed.

So, Does It All Cancel Out?

Here's where I want to be straight with you, because there's a lot of noise on both sides of this topic, and our family would rather give you the full picture than a tidy slogan.

The science on soil carbon is still developing, and researchers don't fully agree yet on exactly how much carbon well-managed grazing land can lock away, or for how long. Some studies looking specifically at adaptive, high-intensity rotational grazing have found that once you account for the carbon being pulled into the soil, the whole finishing phase can flip from a source of emissions to a net carbon sink. Other broader reviews, averaging results across many farms and many grazing styles, find the sequestration numbers are smaller and more variable. 

The honest answer is: it depends enormously on how the land is managed, and management looks different from farm to farm.

What we do know, with a lot of confidence, is this: it's not just the cow, it's the how. A cow raised on a system that's actively building soil is part of a very different carbon story than a cow raised on a system that isn't. Same animal, same species, different surrounding system.

That's a big part of why our family farms the way we do. Cover crops. No-till. Rotational and mob grazing. Papa always says you work for the land, and if you do it right, the land provides. We're not just hoping raising cattle can be part of building healthier ground — we're out there every day, moving fence line, watching the grass come back thicker, and paying attention to what the soil tells us.

So the next time somebody at a dinner party tells you cows are ruining the planet, you'll have a more complete answer ready: it depends a whole lot on how those cows were raised.

Further reading, for the curious:

• Michigan State University's long-running research on adaptive multi-paddock (AMP) grazing, published in Agricultural Systems, found that once soil carbon sequestration was factored in, AMP-grazed beef finishing shifted from a net emissions source to a net carbon sink — while feedlot emissions stayed essentially flat.
• A 2024 life-cycle analysis in PNAS found that grass-finished beef systems that account for soil carbon sequestration show the greatest reduction in overall emissions compared to feedlot systems, though the researchers noted a full shift to grass-finishing nationwide would require significantly more land.
• Not every study agrees on the size of the effect. A 2025 systematic review of regenerative grazing research found that when you look across many farms and grazing styles, the median measured soil carbon sequestration rate is much smaller than the standout studies suggest — a reminder that how the land is managed matters enormously, and results vary a lot from farm to farm.
