This study investigates the impact on CO2 emissions and traffic safety of introducing mandatory speed limiters on European vans. The results show that if the entire European fleet were thus equipped, with limiters set at 110 or 100 km/h, this would lead to respective fuel savings of 4 and 7% for these vehicles. Between 110 and 190 fewer fatal casualties are also anticipated annually, with most of this reduction on motorways. The study also shows that introducing speed limiters on new vans involves no significant costs.
The study was carried out by CE Delft for Transport & Environment (T&E) in response to the European Commission’s planned legislation on van CO2 emissions.
