nonsense. cars, buses, and SUVs (odd distinction, but ok. also why buses?!) account for ~10-15% of global emissions (depending on how you cut it). see https://ourworldindata.org/emissions-by-sector.
it doesn’t refute it, and it wasn’t my intention to do so. i was trying to point out that such an “extreme” position might not be sensible for such a fractionally small amount of CO2 emissions.
What is sensible, about banning a particular journey type for a transport sector that produces even smaller CO2 emissions, and has better fuel economy per passenger seat than (for example) buses and SUVs?
