The study analyzed the effects of banning sales of passenger cars with internal combustion engines on the carbon footprints of passenger car travel in Sweden. The ban resulted in significantly decreased carbon footprints primarily due to reduced tailpipe CO2 emissions, but the full effect was delayed. Increasing the pace of electrification is beneficial for reducing carbon footprints, and a ban in 2030 may not be sufficient to achieve national policy targets.
Banning sales of passenger cars with internal combustion engines is becoming a common climate change mitigation policy. This study analyzes the effects of such a ban on the carbon footprints of passenger car travel in Sweden using a novel vehicle turnover model and prospective lifecycle assessment, with scenarios for decarbonization of supply chains. A ban on internal combustion engines results in significantly decreased carbon footprints primarily due to reduced tailpipe CO2 emissions. The full effect of a ban is delayed due to fleet inertia. Increasing the pace of electrification is beneficial for the carbon footprint regardless of global manufacturing decarbonization pathways. A ban in 2030 is not sufficient to reach national policy targets for the transport sector, requiring either an earlier ban (i.e., 2025) or increased biofuel use. Risks of carbon leakage may motivate extending current regulations of vehicle-specific tailpipe emissions to also cover carbon footprints for new cars.
