countries, the transport fuel consumption of cars was found to be highest in Switzerland, at 8.84 l/100 km.
In the case of newly registered cars, Switzerland also fares poorly with regard to fuel consumption (7.43 l/100 km in 2007) and CO2 emissions. Further reductions will be required not only for greenhouse gases but also for air pollutants – nitrogen oxides (NOx) and particulate matter (PM10) – in order to meet environmental targets.
