I bet they had some "contribution" to help push this through, or vested interests. Give diesels some help and bury everything else? It sounds like the US State of West Virginia, scrapping all alternative fuel incentives except for propane and natural gas vehicles, because an "all of the above" incentive program was designed to promote natural gas vehicles, but everyone bought electric cars instead because there is only one NGV sold in the US, and there was no NG infrastructure at the time (still few and very far in between, EVSE have higher density). Here's that original article:
Plug-in Cars will be More Expensive in West Virginia.
Buying an environmentally friendly car in West Virginia will soon be up to $7,500 more expensive.
The West Virginia House voted unanimously Saturday (4-13-2013) to eliminate the state tax credit that encouraged the sale of solar, electric, plug-in hybrid, and other alternative fuel vehicles.
The tax credit will remain for vehicles that run on natural gas, butane, propane.
Governor Earl Ray Tomblin said the credits had become too expensive. The change is expected to save $6 million in the next fiscal year.
Tomblin's administration said the credits' original purpose was to promote natural gas, which is produced in the state. Most of the electricity that powers plug-in cars is also produced in the state.
The bill also eliminates tax credits for building infrastructure for alternative fuel vehicles.
Note that West Virginia is one of the highest coal producing states in the US, which nearly all goes to power generation.
This move by the Danish government is nothing about environmental performance, it's about money. And scrapping EV incentives is the easiest thing to do.
