I can't work out if this is a real thread or not... but here goes....
The biggest impact of manufacturing, is transporting goods to different countries, most are shipped by sea or land, to not do this, would mean having manufacturing on each continent at least, and then every mould would have to be made at least 5 times, then you got local tolerances... then, for moulded items, you got to get the raw material to the locations to. So instead of one plant turning out, you want five smaller, less efficient ones?
The only way to reduce footprint efficiently, is manufacturers to have a 'recycling' facility, so your broken parts can go back, be ground down and possibly re-used, especially tyres.... but then you have to ship the worn/broken stuff back?
