  1. Eric Stonebraker says:

    “We find that although food is transported long distances in general the GHG emissions associated with food are dominated by the production phase,83% of the average U.S.household’s 8.1 t CO2e/yr footprint for food consumption.Transportation as a whole represents only 11% of life-cycle GHG emissions, and final delivery from producer to retail contributes only 4%.”

    Shifting less than one day per week’s worth of calories
    from red meat and dairy products to chicken, fish, eggs, or a vegetable-based diet achieves more GHG reduction than buying all locally sourced food.

    I have also heard that a very large % of total energy consumed comes from the shopper’s drive to and from the grocery store. Given this, I think any food localization efforts should also focus on food transport issues, eating lower on the food chain, and NOT driving to the grocery store…
