The Emission Impacts of Car Clubs in London

The focus of this report is a description of a new analysis of the 2010/11 annual survey of car club - a form of neighborhood car rental - users. Car clubs offer an alternative to private car ownership, and the survey helps to understand the car clubs' potential emission impacts in London. Car club members report, on average, substantially lower levels of household car use than the average London household, as shown by the analysis, than the average London household with at least one full car license holder. Pre-joining travel behavior is also reported to involve much greater household car use than for established members. Also reported is the fact that car club vehicles tend to be newer and cleaner than the average private car. From car use by households with established London car club members, average estimations of emissions of CO2, NOx and particulate matter (PM)10 are less than half of the equivalent emissions estimations for London households with at least one full car license holder, or for the pre-joining household car use by those who have recently joined. Different subgroups of car club users were considered in order to establish the robustness of these results. Increases in car use by non-car-owning households, as well as by households whose personal car ownership also increases, are shown to occur after joining car clubs. However, compared to the large average reductions in household car use by those who reduce their household car ownership, these increases are relatively small - meaning that the average changes calculated overall seem robust. Overall, after joining a car club, about 30% of car club members report reducing their household car ownership, and another 30% report that they would have otherwise purchased a vehicle (including a proportion of those who dispose of a car).
