Greta is a hypocrite. It is well documented that manufacturing an EV has a considerably larger carbon footprint than an ICE vehicle. It can take 10 years of driving before that excess carbon footprint breaks even. That does not take into consideration the possibility that EV is still on the road after 10 years (accident, battery fire, obsolete, no replacement battery).
She owns over $100,000 of electric vehicles. A 3rd Gen Tesla, a BMW i5 and a Camry hybrid. It will take her 30 years of driving just to break even by her standards.
