Cars may get expensive in Sweden next year as authorities move in to curb emitting more carbon dioxide.
The move is thought to be strategic in reducing the pollution of air and its effects on the climate as the fees are designed to penalise high-emissions cars.
Effectively, cleaner cars that do not emit carbon dioxide to the air will be cheaper than dirty cars.
Under the Swedish system, cars with higher CO2 emissions cost more, and the cleaner cars cost less.
This, authorities say was to make car users move to a transport system that is less damaging to the climate.
The Swedish government has said that climate change is one of the most pressing challenges globally and a broad range of policy instruments can be used to curb carbon emissions.
The government says there was need for economic instruments such as taxes and emissions for any comprehensive mitigation strategy.
