Is Local Produce Always Lower Impact
Launch library · evergreen read

Buying local produce is often assumed to automatically mean a lower environmental footprint, largely because it seems intuitive that shorter transport distances should mean fewer associated emissions, but transport is frequently a relatively small part of a food product's total environmental footprint compared with how that food was actually grown or raised.
Food grown out of season in an artificially heated greenhouse close to home can, in some cases, carry a higher overall footprint than the same food grown in its natural season somewhere further away and then transported efficiently in bulk, since growing conditions and production methods often matter more than the distance travelled.
None of this makes buying local pointless, since it can support local farming communities and genuinely reduce impact in many specific cases, but the fairest general approach considers seasonality and how food was actually produced alongside distance travelled, rather than treating proximity alone as an automatic, reliable guarantee of lower environmental impact.
