This article reports the results of a package of environmentally-linked parking charging policies designed to reduce the environmental impact of the parking fleet in Winchester. These measures were implemented as part of the EU-sponsored CIVITAS MIRACLES project which ran from 2002 to 2006. The measures included a variable tariff for annual parking permit holders at several long stay car parks in the city centre, offering a discount of 75 percent or 50 percent for those vehicles in the two lowest CO2 tax bands, with free annual permits offered to owners of electric or hybrid vehicles. In addition, a differential parking charging policy was implemented to discourage long stay parking in the city centre and encourage the use of off-centre and peripheral car parks such as the Park and Ride. This article includes the results of the scheme, a review of other existing schemes and the conclusions and recommendations drawn from the evidence.
