Swedish cars found to be dirtier than thought

1:31 min

Those looking to buy a new car next year can expect it to cost more, because new, more stringent emissions tests show cars are emitting more carbon-dioxide than was previously estimated.

Sweden has a system whereby cars with higher CO2 emissions cost more, and the cleaner cars cost less, to get the market to move towards a transport system that damages the climate less.

The average price increase per car will be SEK 2,600, reaching as much as SEK 10,000 more.

And even some of the cars that used to be associated with a bonus, because they were so "green" are now found to have much higher emissions with this new system, meaning they also will be part of the penalty tax.
