Cities that have implemented congestion charging have experienced a range of benefits including up to 30% less traffic, reduced congestion, lower emissions, and revenue from the scheme improving transport options.

This report discusses how congestion charging can become an equitable part of a decarbonised transport system in Aotearoa New Zealand.
