“…To be realistic, models needs to study the impact of at least vehicle taxes, road taxes, fuel taxes, regulations, standards and biofuel mandates, since these are very common across the world, often all used simultaneously. Some recent studies recognise this limitation of current IAMs and integrate additional policies, including fuel taxes, registration or road use (Deetman et al, 2013, Yin et al, 2015, Zachariadis, 2005; Technology subsidies and mandates (Bertram et al, 2015, Deetman et al, 2013, Yin et al, 2015, Zachariadis, 2005; efficiency policies (Deetman et al, 2015, Siskos et al, 2015, Yin et al, 2015, Zachariadis, 2005, biofuel blends and mandates (Calvin et al, 2014). The FTT model includes eight policy instruments (vehicle taxes, registration taxes, fuel taxes, vehicle subsidies, regulations, fuel economy standards, biofuel mandates and possible kick-start programs) and can be used to model policies for each individual countries.…”
