For me it is more about simple polution. CO2 only being one (important) part of that equation.
Tyres of electric cars polute the same as ICE, but perhaps we could all breathe a bit easier outside the school gates or in towns etc. If everything was electric...
(Speaking as someone who has an asthmatic in the family).
So from a reducing polution point of view, i personally cant understand this government's 'choice' to de-incentivise electric cars.
The greedy Liberal govt did a similar thing over here. Added the fuel excise onto LPG that produces next to no carbon monoxide.
Yrs ago, they added the fuel excise tax onto heating oil ..... how can there be a claim for road upkeep for a fuel used to keep the place warm ..... this resulted in a surge of wood burners resulting in licences required to collect firewood, any excuse to collect more $$ to fund their incredibly over the top pensions, pay and perks .....
The argument over here now revolves around pay by the km should be for all vehicles with a multiplication factor to take in the weight per tyre on the road x the number of tyres contacting the road ..... and scrap the fuel excise completely .... that has put a shudder through the govt, if it is a road tax, then it must go to roads

what about my pension and perks .... they can't openly say that but .....
There should be a health tax on the level of pollutants produced by any fuel ..... but that sounds like a carbon tax and we had a govt change over that one, so no one is game to put that one forward ...... but once the govt sponsored but privately owned (they sold them to their mates) coal fired power stations close because they can't compete with renewables.
They actually have to pay to generate into the grid through the days there is enough renewables to cover the load because they can't just stop spinning them, so they get their money back after sun down and before sun up, now that peak load demand is being eaten away by big batteries, the market is fading ..... naturally, the coal lobby is pressuring the govt to slow down the big battery projects, but that has backfired because the big solar and wind investors just coughed up the $$ to add big batteries on site, so they no longer have periods of no generation, it just goes into the batteries ....
The govt is running out of ideas on how to generate more tax $$ ..... I wonder if they'll bring in a compensation payment if they introduce a sex tax
