When you get into a new taxi in Copenhagen in 2025, it should emit neither CO2 nor any kind of air pollution. This is the Danish government's objective for the taxi industry, which must take the lead in the green transition like public bus traffic, according to local politicians. The app-based taxi service, DRIVR, is one of the taxi companies that is at the forefront of the green transition. As a customer it has long been possible to choose between hybrid, electric and hydrogen cars. Now DRIVR significantly increases the number of hydrogen taxis in the fleet and has put over 100 hydrogen taxis on the roads in Copenhagen at the beginning of November in collaboration with Toyota. All 100 cars are Toyota Mirai fuel cell vehicles, the world's first mass-produced hydrogen car, only emitting water while driving.
