The congestion charges in Stockholm are one of the first in the world to have been implemented and, with that, came substantial political and technical risk. The objective of the Stockholm congestion charges was, and partly is, to reduce congestion and reduce environmental effects of car traffic.
These objectives have been extensively evaluated and reported on in both political, professional, and academic literature.
Currently, the challenge is to constantly re-evaluate how congestion charging can contribute to overall (transport) political objectives, with the primary objective being to use the revenues to facilitate the city of Stockholm’s sustainable growth rather than to raise revenue.
As the city changes and develops, the congestion charges need to change. This policy, which was introduced and is in place10 years’ later, represents a policy and technological innovation.
