According to a technical, Danish news outlet (ing.dk), the above article is based on the Danish prime minister's speech at the opening of parlament (following their summer break), the actual speech is here:
Statsministeriet - Statsministerens tale ved Folketingets åbning, 2. oktober 2018
In this speech, he specified his government's goal of forbidding newly sold, pure ICEs from 2030 and to allow only ZEVs from 2035. Understandingly, this speech does not differentiate hybrids and plugin-hybrids.
The context of this information is important. Danish politicians are not fundamentally different from politicians in other countries, so there is a non-zero risk that (due to wholly unforeseen circumstances) the current government's stated goals will not actually materialize.
By accepting a ban from 2030 the government would actual help legacy automakers to transform. Legacy follows only legislation and I don't see additional effort. If they would let them they would produce ICE for 20-30-40 years. If BMW and other will success to stop such legislation than they are really doomed. Can you imagine where will be Tesla&co. after 12 years with no competitors?
Short term victory would mean death after.
