The purpose of this report is to provide summary information of the policy instruments that have either been implemented or are under discussion in order to reduce vehicle kilometers travelled (VKT) by cars and trucks in the state of California and in Sweden. The summary is based on a review of policy documents, reports and scientific papers that are relevant for both cases, as well as interviews with a senior policy advisor from California, and a professor with more than 30 years of experience in a wide range of issues within the fields of transport analysis, transport modelling and transport policy within the Swedish context, from Lund University, Sweden. In both cases, reducing VKT is mainly linked to reaching policy goals of reducing greenhouse gas (GHG) emissions. In both cases, this is considered an effective strategy for reducing GHG emissions. However, both cases appear to be engaged in an exploratory process with respect to the development of both policy and policy instruments for reducing VKT, even if the cases appear to be in slightly different stages of this exploratory process.
