Food miles: the most useless way to measure the impact of food

Here are the facts:
📦 Transport only causes 4.8% of all greenhouse gases from food
🚚 Most of those emissions happen during local/regional road transport
🚢 Shipping covers the largest distances but only causes 0.17% of all food emissions

➡️ Paying attention to where your food comes from doesn’t reduce the carbon footprint.

Here’s a good rule of thumb: think of how much space was necessary to grow that food, not how far it had to travel.

🥥 Coconut milk: one palm tree → low impact
🥩 Beef: fields of grass (and maybe even corn) to feed a cow → high impact

So if your plant-based recipe includes coconut milk from across the world, that’s okay.

People don’t like hearing this…

There are still benefits for promoting a *local food system*:
– more transparency
– more connection to our food and landscape
– more local crops and higher biodiversity

But once you enter the supermarket, you’re already part of the global food system. In that context, paying attention to food miles is useless.

I think this is good news, because it makes sustainable food choices simpler: make animal foods a luxury and don’t worry so much about all the other stuff.

What do you think? And what does it make you feel? 😉
