Not bad for a country of 5 million people. Perhaps the greatest answer to sceptics is that the bike highway plan isn’t a stand-alone scheme. It’s just one of a host of measures in the new National Transit Plan to clean up Norway’s transit pollution. By 2030, 75 percent of the country’s buses and 50 percent of its trucks must be low-emission, the new plan rules, while 40 percent of its short-distance ships and ferries (an important means of transit in Norway) must be either low emission or use biofuels.
