"Imported vegan food pollutes in transport."

The answer in one sentence

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.

Ask a question back

"If transport is a small fraction of emissions, what weighs more: the distance or what you eat?"

Disguised version

The strongest version

How it is said

"Your tofu comes from far away. The neighbor's beef pollutes less than imported nuts."

Strongest version (steelman):

  1. P1Transporting food emits greenhouse gases.
  2. P2Many vegan products are imported or travel long distances.
  3. P3Local foods avoid those emissions.
  4. 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.

Full answer

  1. a

    Reconstruction and diagnosis

    The argument overestimates the weight of transport:

    Source of emissionsRelative weight
    Land-use change and on-farm productionMost of the emissions, especially for meat
    TransportLess than 10% for most foods; about 0.5% for beef
    Air freightVery polluting, but about 0.16% of food transport
  2. 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

  4. 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.

  5. 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.

  6. f

    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?

Reasoning errors

Epistemological

Does the evidence support it?

Overestimating one factor
Treats transport as the main source of emissions

Logical

Is the form valid?

Unequal comparison
Compares distance, not production
Tu quoque
Accuses vegans instead of comparing impacts

Biases

Salience bias

Transport is visible; farm emissions aren't

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

Eats imported products.

Coffee, chocolate, bananas and many others.

Ignores the emissions from producing meat.

Which are much greater than those from transport.

Also eats local vegan foods.

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.
