Food miles

The distance food travels between where it’s grown, and where it’s bought. This simple measure is becoming increasingly discredited as a way of ascertaining the impact of food, as a product having a high number of food miles doesn’t necessarily mean it has a high carbon footprint. Transport by road has a much lower climate impact than airfreight, and shipping significantly lower than both. The use of heated glass to grow crops in the UK (where we don’t get the heat and sun needed to grow some crops, like strawberries and tomatoes, year round) can mean that it’s much less impactful to truck produce from the continent than to grow out of season locally.
