HomeEstimating the costs and benefits of introducing a new European evaporative emissions test procedure
Publication metadata
Evaporative emissions of non-methane volatile organic compounds (NMVOCs) arise from the vehicle’s fuel system under changes in ambient and vehicle temperature and as a consequence of fuel permeation through plastic material. NMVOCs contribute to ground-level ozone and urban smog and pose a threat to human health. A revised test procedure for evaporative emissions and its possible implementation is currently under discussion by the European Commission. This study undertakes a cost-benefit analysis of four possible scenarios for the implementation of a revised test procedure for the period 2015-2040. Indirect cost multipliers (ICM) were used to estimate short- and long-run costs to the manufacturer. The COPERT model used to estimate EU evaporative emissions from the Euro 6 petrol vehicle population over time. Low and high marginal damage costs for NMVOC emissions from the CAFE Programme were used to calculate the economic value of the damage avoided. The study concludes that the most beneficial strategy is the implementation of a more aggressive purging strategy over 48 hours and greater canister durability (scenario 2+). The average net benefit of implementing scenario 2+ is €146,709,441 at a 6% discount rate is considerably higher than the other scenarios considered. Under scenario2+, the per vehicle benefits range from €6-9 but when fuel savings benefits are added, total benefits range from €13-18. This is compared to average additional cost per vehicle of €9.
