I was thinking of total energy (and maybe something like CO2) per food on the customer's table, including the waste that's produced.

For me personally it doesn't tract that reducing the supply chain between producer and consumer to the maximum will result in more energy expenditure:

The supplier has one trip to make to sell their current stock.

The consumer has one trip to make to buy multiple items that they're interested in (since this is a market).

Great quote on that from Vaclav Smil's new book: " each greenhouse-grown, supermarket-bought tomato has the equivalent of five tablespoons of diesel embedded in production"
