"Imported vegan food pollutes in transport."
transport is a small part of food emissions: for most products, less than 10%, and for beef, about 0.5%. What you eat weighs far more than how far it traveled. A kilo of beef emits about 60 kilos of CO₂ equivalent; a kilo of peas, about 1. Swapping meat for plants cuts emissions far more than eating local.
Short answer
Transport is a small part of food emissions: for most products, less than 10%, and for beef, about 0.5%. What you eat matters far more than where it comes from. A kilo of beef emits about 60 kilos of CO₂ equivalent; a kilo of peas, about 1. Even shipped from far away, plants emit much less than local meat, except for the few foods that travel by air.
For children
Bringing food from far away uses a bit of fuel. But what pollutes most is making the food, not carrying it from one place to another. Raising a cow pollutes much more than growing peas, even if the peas come from far away.
"If transport is a small fraction of emissions, what weighs more: the distance or what you eat?"

"Your tofu comes from far away."
"The neighbor's beef pollutes less than imported nuts."
"Eat local."
"A vegan eating avocados from Mexico doesn't care about the planet."
"The carbon footprint of food transport is significant."
"Local, organic meat is sustainable." (which is H8)
The strongest version
"Your tofu comes from far away. The neighbor's beef pollutes less than imported nuts."
Strongest version (steelman):
- P1Transporting food emits greenhouse gases.
- P2Many vegan products are imported or travel long distances.
- P3Local foods avoid those emissions.
- CSo eating local meat can be more sustainable than eating imported vegan products.
P1 and P2 are true. So is P3, in part. The problem lies in the conclusion: it assumes transport is a large part of emissions, and it isn't.
The argument is valid. Its soundness fails because transport is a small fraction of food emissions.

Reconstruction and diagnosis
The argument overestimates the weight of transport:
Source of emissions Relative weight Land-use change and on-farm production Most of the emissions, especially for meat Transport Less than 10% for most foods; about 0.5% for beef Air freight Very polluting, but about 0.16% of food transport - b
Where the argument breaks
1. Transport weighs little.
According to Our World in Data, transport accounts for less than 10% of the emissions of most foods. Across whole diets, about 5% to 6%.
2. The type of food weighs much more.
A kilo of beef emits about 60 kilos of CO₂ equivalent; a kilo of peas, about 1. No transport distance makes up that difference.
3. Most international food trade travels by ship.
Ships emit little per tonne carried. Air freight, the more polluting option, is a tiny fraction, and mainly affects fresh, perishable foods.
4. Eating local doesn't solve the problem of meat.
Local meat still carries the emissions of production, which are most of the total.
5. Many vegan foods are local.
Grains, beans, potatoes, corn and vegetables are grown in most regions of the world.

Data and sources
Source What it says Note Our World in Data, food choice versus eating local Transport is less than 10% of the emissions of most foods and about 0.5% for beef; 1 kg of beef emits about 60 kg of CO₂ equivalent, and 1 kg of peas, about 1 Based on Poore and Nemecek, 2018 - d
The strongest counter-reply: some foods come by air
The most serious version grants that shipping weighs little, but points out that fresh, perishable foods sometimes come by air, which greatly increases emissions.
- e
Why the counter-reply doesn't reach the conclusion
Air freight is rare.
About 0.16% of food transport.
Avoiding air-freighted foods is easy.
Just prefer seasonal or long-lasting products.
Even by air, beef emits more.
The difference in production is still greater.

Back to the moral question
Transport is a detail in emissions, and even if it weighed more, it wouldn't answer the question about the animals. Local meat also comes from animals raised and killed. If it's possible to eat well on plants, local or not, what justifies that cost?

General literature on heuristics
Extrapolations
The principle being tested is: "what's local is more sustainable".
If it applied to…Tomatoes from local heated greenhousesTap to see
They'd be better than tomatoes imported from warm climates
They often emit more
If it applied to…Local beefTap to see
It would be better than imported peas
It emits dozens of times more
If it applied to…Any productTap to see
Local would always be better
Production weighs more than distance
Contradictions
Coffee, chocolate, bananas and many others.
Which are much greater than those from transport.
Grains, potatoes, vegetables.
What the argument gets right
What is true
Buying local food can have benefits, such as supporting regional producers and reducing waste. Air-freighting perishables is indeed polluting, and worth avoiding.
But
But for the climate, what you eat weighs far more than where it comes from. The most effective change isn't shortening the distance; it's swapping meat for plants.
