If your only use for a vehicle is a weekly or even daily trip around the block to buy a pack of eggs, the best environmental choice is to use a vehicle that is already manufactured. If the only vehicle available to you is a semi truck, that’s the best choice. Even over a lifetime of daily trips, the difference in emissions between the semi truck and a golf cart won’t make up for the emissions of manufacturing the golf cart and transporting it to you.

Of course this is a contrived example that ignores the used vehicle market or the possibility of walking around the block.
