It's why the "buy local" movement wouldn't really save much CO₂. Driving the trucks from the harbour to the consumers emits more, AIUI.
The majority of CO2 from moving food is created by you driving to the supermarket for groceries. It's not hard to see how when you compare a 15 ton truck moving 30 tons of food, compared to a 2 ton car moving 4 kg of food. That truck can move 1000 times further than a personal car for about the same amount of CO2 per kilo of food.
This same logic means it's more efficient to buy tomatoes from a continent away than to drive to the market to buy tomato seeds.
Farmers co op shares a central processing and distribution facility. Beef travels 30 minutes in and out to final destination. It all happened in a local region it’s local.
Yes, that's right.
Cow raised 10 miles from my house. Killed on farm butchered on farm. I pick up cow and drive it 10 miles to my freezer. Cow sits in freezer for 1 year with other frozen farm products.
What are you talking about? I’m so confused at what you think buy local means?
Right, that's buying local. As opposed to having a cow raised 2000 km from your house and the meat shipped to you, which would be not buying local.
I'm not sure what you're confused about.
But shipping doesn’t eliminate the truck driving from the harbour to the grocery store - that’s still needed. It just also adds a ship.
Yes, all things being equal that's true.
The first point is that even if it is true, for some products producing them takes much more energy than moving them. Cows are the extreme example, IIRC, where raising cows for meat takes like 80 times as much energy as delivering it.
The second point is that all things are rarely equal. You can raise bananas in a greenhouse, for example, but it will be a lot less energy efficient than shipping it from the tropics.
Yeah, that's a good point. But I've always looked at the buy local movement as a way to fuck over billionaires.
I'm totally in favor of buying local! It preserves local culture, helps your neighbors, and deprives capital of a way to exploit people out of sight. The food is fresher, and having to cook with seasonal ingredients adds variety and gives fun challenges.
But it won't prevent much carbon from entering the atmosphere.
