What happens if the combustion ban falls?

What would happen if the de facto ban on combustion engines were to fall next year, assuming the outcome of the European elections? The Vienna Engine Symposium, which brought together more than 1,000 drive experts at the end of April, provided a perspective, and it was by no means limited to the unrestricted renaissance of the reciprocating engine, as Messrs. Otto and Diesel once thought. First of all, not only car manufacturers, but also truck and tractor manufacturers would have to think about how the goal of climate neutrality could still be achieved. And what bets they are willing to make, i.e. where they accumulate capital. There is agreement that an internal combustion engine that is not harmful to the climate can only be achieved if the burning of the fuel only releases as much carbon dioxide into the atmosphere as was previously bound.
