There's something to be said for letting the market decide. Something like a carbon tax would probably be a more economically effective way of dealing with CO2 than arbitrarily choosing this of that industry as a winner which hasn't exactly worked in terms of controlling carbon emissions. I think they are up about 80% since people started going on about them.

I'm an example of someone who doesn't fit the obvious ban combustion engine model. I own a German combustion engine car but don't use it much as I mostly get around by ebike + train.

Tax carbon rather than dictating which technology! My biggest emissions are probably gas heating and flights both of which have approx 0% tax so forcing me to get an electric car isn't really going to fix that. I'm not really a climate doomer but if you are, current policies are a good way to get doom.

Germany has a carbon tax* on fuel for cars. It will merge with the EU scheme when that expands to this sector and home heating in 2027.

And that EU scheme already covers aviation, though it's phased in with exemptions etc. so doesn't cover everything.

*Technically an emission trading scheme but these are basically equivalent to carbon taxes in effect.
