One of the main issues with food miles as far as I can see is the varying degrees of environmental damage that different modes of transport do to the environment. The four main methods of freight; sea, air, road and rail, produce different amounts of CO2 equivalent emissions per tonne transported.
while food miles can help us decide between products if we are trying to shop sustainably, it turns out that only 12% of the greenhouse gas emissions attributed to food are down to transportation.
