The move comes as the airport struggles to meet its current emissions targets. Since flight emissions are almost impossible for a single airport to limit, the airport is instead mulling the option of trimming its emissions through a reduction in car traffic.
Arlanda is set to submit its application for new environmental targets at the end of this year. The airport requires permission from the government before it can charge a toll to drivers.
If implemented, the proposal recommends that car drivers pay 50 kronor on their way in to the airport and a further 50 kronor on their way out from 2012. But airport authorities stressed that the levy would only come into force if there was a concurrent improvement in rail and bus services to and from the airport.
"Otherwise it's just a punishment tax and we don't want that," airport spokesman Jan Lindqvist told Dagens Nyheter.
Drivers of environmentally friendly "green cars" would not be required to pay the toll, while airport staff and truck drivers would pay a reduced charge of 20 kronor each way.
