As far as i know, no country has made any of this law as yet. They are only targets to aim for or goals if you like. Somewhere like Norway already sells almost as many electric and hybrids as it does pure ICE vehicles. By 2030, which is the earliest you can expect any country-wide bans (a lot of this proposed legislation concerns only major/capital cities for now), the proportion of new ICE vehicles manufacturers will have available will be minuscule. There will be no mass-scraping of ICE vehicles, they'll just naturally phase out over their regular useable lifespan as more and more buyers see the benefits of non-ICE. By that time battery power, and whatever non-fossil fueled ICE technology is favoured will be much more efficient than it currently is.
