Food miles --> carbon tax
The best way to choose food purchases, or any product, in order to minize carbon impact is to analyze the total carbon footprint throughout the lifecycle.
Unfortunately that's very complicated requiring lots of data collection and analysis and lots of guesswork. Food miles is a poor proxy for this, easier to calculate.
A much better and simpler alternative is a carbon tax. If major sources of carbon (starting with fuel) were taxed to reflect their true environmental impact, consumers would have a simpler choice to make based on price.
