"Local, organic meat is sustainable."
"organic" and "local" say little about meat's emissions and land use. The lowest-impact beef, from the 10% most efficient producers, emits about 9 kilos of CO₂ equivalent per 100 grams of protein; the highest-impact peas, about 0.8. Even the best beef emits more than ten times as much as the highest-impact peas. And pasture-raised meat usually requires even more land.
Short answer
Organic and local help in some ways, but they don't change the essentials: meat emits a lot and uses a lot of land. According to Poore and Nemecek's data, the most efficient beef emits about 9 kilos of CO₂ equivalent per 100 grams of protein; the least efficient peas, about 0.8. Even the best beef emits more than ten times as much as the highest-impact peas. And pasture-raised meat usually requires even more land.
For children
Organic meat doesn't use certain medicines and poisons, and that's good. But the cow still releases gases and needs a lot of space to live. Even the most carefully produced meat pollutes much more than growing beans or peas.
"If the lowest-impact meat emits ten times more than the highest-impact plant, sustainable compared with what?"

"I buy organic."
"Grass-fed beef is sustainable."
"Eat local."
"Meat from small farmers has no impact."
"Extensive pasture systems are more sustainable."
"Free-range animals are happy." (which is B2)
The strongest version
"I buy organic. Grass-fed beef is sustainable. Eat local."
Strongest version (steelman):
- P1Intensive livestock farming causes serious environmental harm.
- P2Organic, local, pasture-raised meat avoids some of that harm, such as pesticides, antibiotics and transport.
- P3So that meat is sustainable.
- CSo those who eat it don't contribute to the environmental problems of livestock farming.
P1 is true. So is P2, in part. The problem lies in P3: avoiding some harms doesn't make production low-impact, and emissions and land use remain high.
The argument is valid. Its soundness fails at P3.

Reconstruction and diagnosis
The argument compares "good" meat with "bad" meat, not with the alternatives:
Comparison Result Organic versus conventional meat Fewer pesticides and antibiotics; similar or higher emissions Pasture-raised versus feedlot More land per kilo; emissions per kilo often similar or higher Best beef versus worst plant protein About 9 against 0.8 kg of CO₂ equivalent per 100 g of protein - b
Where the argument breaks
1. The best meat still emits a lot.
According to Our World in Data, the 10% of beef producers with the lowest impact emit about 9 kg of CO₂ equivalent per 100 g of protein. The 10% of pea producers with the highest impact emit about 0.8.
2. Organic doesn't mean low emissions.
Organic certification concerns pesticides, fertilizers and antibiotics, not methane emissions or land use.
3. Pasture-raised meat uses more land.
4. Local weighs little.
Transport is a small fraction of meat's emissions (H7).
5. "Good" meat is a small fraction of consumption.
Most meat comes from conventional production (B2).

The strongest counter-reply: it's better than conventional meat
The most serious version grants that organic, local meat isn't low-impact, but says it's better than conventional meat in some respects, such as welfare and chemical use.

Why the counter-reply doesn't reach the conclusion
Better than the worst isn't good.
The relevant comparison is with plant alternatives.
It isn't always better.
On emissions and land use, pasture-raised meat can be worse than conventional.

Back to the moral question
Even the most sustainable meat still comes from an animal raised and killed. The environmental question is important, but it isn't the only one: if meat were neutral for the planet, the question about the animal would remain. And it still has no answer.

Halo effect
The "organic" label makes the product seem better in every way
General literature on the halo effect
Extrapolations
The principle being tested is: "if a product is better than its conventional version, it's sustainable".
If it applied to…An efficient gasoline carTap to see
It would be sustainable, because it's better than an old car
It still emits a lot
If it applied to…An "organic" cigaretteTap to see
It would be healthy
No one concludes this
If it applied to…Organic meatTap to see
It would be sustainable
It still emits far more than plants
Contradictions
Outside the home, meat almost never is.
Which is greater for pasture-raised meat.
But doesn't change the choice.
What the argument gets right
What is true
There are real differences between production systems: fewer pesticides, fewer antibiotics and sometimes better welfare. People who look for organic, local meat care about the impact of what they eat, and that concern is valuable.
But
But for the climate and for land, the best meat is still far worse than plants. And for the animal, the ending is the same.
