Transport

• Fuel consumption by road, rail, shipping and aviation sourced from IEA energy balance

• Transportation modes in the model include the following

  Mode	Demand	Units
  RAIL	Freight	Petajoules
  RAIL	Passengers	Petajoules
  ROAD	Auto	Billion vkm
  ROAD	Light Trucks	Billion vkm
  ROAD	Three Wheels	Billion vkm
  ROAD	Two Wheels	Billion vkm
  ROAD	Bus	Billion vkm
  ROAD	Heavy Trucks	Billion vkm
  ROAD	Medium Trucks	Billion vkm
  ROAD	Commercial Trucks	Billion vkm
  Aviation	International Aviation	Petajoules
  Aviation	Domestic Aviation	Petajoules
  Shipping	Domestic Navigation	Petajoules
  Shipping	International Navigation	Petajoules
  Non Energy Uses	Non Energy Uses	Petajoules

• Road is modelled on a technology basis with stock representation, non-road transport on a fuel substitution basis

• Starting values for vehicle fuel efficiency, mileage per year, vehicle stock are sourced from reputable sources (eg NEMS, JRC-EU-TIMES, others) and are adjusted to match the total fuel consumption reported in IEA energy balance
