Rebound effects represent the difference between anticipated or projected energy savings and the real energy saving in relation to, for example, implemented policy measures aimed at improving energy efficiency. Rebound effects in the transport sector may counteract policy measures so that goals related to energy or emissions are not achieved, or achievement is greatly delayed. This comprehensive report examines the presence of rebound effects within the transport sector and while the aim was to provide a full review of the issue, for some transport areas it was not possible to find any studies on rebound effects. Those areas are identified as having knowledge gaps. We summarize the literature for rebound effects for passenger vehicles, technological developments, freight transports, public lighting, aviation, waterborne transports and for indirect, economy-wide effects, and also discuss rebound effects in aspects of environmental awareness and in the transport and community planning. The existing literature suggests that rebound effects exist to varying degrees and that there is a high risk of energy efficiency measures transferring transport energy savings into other transport modes, sectors or energy services. Consequently, rebound effects should be included when calculating whether Sweden will reach its climate and energy goals.
