Norway has firmly established itself as the most friendly country in the world for electric cars.
Cars with plugs account for a higher percentage of sales there than anywhere else.
But the Scandinavian country may soon take even more aggressive steps to reduce its transportation-related carbon emissions.
"We want to have a car-free center," Lan Marie Nguyen Berg, the lead negotiator for the Norwegian Green Party in Oslo, told reporters last week.
The plan is reportedly endorsed by all three of the political parties that make up Oslo's city council: the Green Party, the Labor Party, and the Socialist Left.

Some European cities have introduced temporary bans to combat pollution or limit traffic, and many have "pedestrianized" streets or neighborhoods, banning regular vehicle traffic.
But Oslo's proposed action would be the first comprehensive, permanent ban in a European city.
With fewer cars around, city officials plan to emphasize alternative forms of transportation--more practical in Europe than in large swathes of the U.S. dedicated to low-density suburban developments.

The proposal also calls for the construction of more than 35 miles of bike lanes by 2019, and bolstering of Oslo's public-transportation infrastructure.
Trams, buses, and delivery vehicles would still be allowed in the city center, and arrangements would also reportedly be made for cars transporting disabled people.
Most car owners in Oslo live outside the city center, but within the city's boundaries.

In fact, the majority of Norway's car-driving population lives in the greater Oslo area.
The fact that so many people live within a relatively short distance of the city center has boosted the popularity of electric cars in the country, because it allows for short average commutes.
On the national level, there has also been a proposal to make close to 100 percent of new cars sold in Norway emission-free by 2025.
It's part of a larger plan to cut carbon emission by 40 percent from 1990 levels over the next 15 years.
