The subsidies were categorized with an intuitive traffic-light system, which helped directing corrective measures toward those which are the most harmful (Finnish Ministry of Finance, 2016). In Norway, electric vehicles are exempted from VAT, which (among other incentives) has made Norway a global leader in electric car use - electric vehicles now have a 23 per cent market share of all new cars sold in Norway (IEA, 2016b). The country has operated a feed-in tariff system for wind power ever since the 1990 (International Renewable Energy Agency [IRENA], 2013), lifting the share of wind power from 3 per cent to 42 percent in electricity production (IEA, 2016a).
