All this Zero Emisions does make me laugh! What about the power stations used to make the electricity? AH! Nasty Nuclear and gas/coal burning shut them down! Think aboiut it. I take a vehicle a disiel Discovery, now 16 years old. Beyond economic life, note Economic, nothing actually wrong with it a bit of tlc and perfectly road worthy, so I use bits from another scrap Discovery , recycling, very green. So I have saved all the material and CO2 required to manufacture a new vehicle, a lot of the CO2 that would be generated by scrapping the second vehicle. Most of what is left from the scrap vehicle was used to rebuild other vehicles, what was left went to be recycled as scrap.
