Drivers in the U.S. have longer commutes than those in Europe and Asia, on average. In the U.K., short commutes in vehicles with combustion engines—whether gasoline or diesel—pose particularly tough emission problems. That's because the exhaust aftertreatment systems have to warm up fully before they cut emissions to the levels... Combustion engines: high emissions from short commutes a huge challenge
