Impressive reductions in diesel pollution for sure - same thing happening here in London.

but but aren't electric vehicles of all types just as polluting, if not more than their ICE counterparts? I am sure that's what I read in many of the UK papers at various times and they wouldn't tell fibs...................would they ? so how could the air quality be better using electric buses

I followed a diesel bus up a hill yesterday. I can very easily believe that one bus can cause as much polition as 1000x ICE cars!

I have read that the most polluted parts of London are train platforms.

The myth that "personal transport is bad and public transport is good" from an environmental point of view needs to be squashed!

Yeah, because apparently no one ever talks about brake dust and tyre wear and that all EVs are as heavy as Sagittarius A*

Urban busses are a GOOD match for EV. Frequent start/stops (regenerative braking) and duty cycle (significant fraction of time at stops.

Not that "Diesel pollution" is why se saw the brief experiment with "Stirling" busses come to a halt. Stirlings would seem to be clean burning BUT to get the high efficiency Stirlings are capable of, burning SO HOT that oxides of Nitrogen are formed << Diesel smell >>
