After all, if we buy local products rather than products made halfway around the world, we will save all the carbon emissions required to ship them to us. It also seems to make sense that rising fuel prices will lead to a decrease in international trade, as companies reduce fuel use by assembling things closer to markets.This facile intuition can lead us to some very inaccurate conclusions. The manufacture of materials typically accounts for far more of their embodied carbon than their transport, and the mode of transport will also have a big impact on embodied carbon.Here is a chart showing the associated CO2 emissions of various modes of transport :Air plane (air cargo), average Cargo B747 500 gModern lorry or truck 60 to 150 gModern train 30 to 100 gModern ship (sea freight) 10 to 40 gWith trucks emitting far more CO2 per mile than cargo ships, a ...
