GreenhouseGasEmissions_Sector_Transportation_ENPassenger and freight travel emissions are influenced by a variety of factors, including population and economic growth, vehicle type, fuel efficiency, and fuel type. Changes in the mix of vehicle type used, such as the increasing preference of passenger vehicle owners to choose light trucks rather than more fuel-efficient passenger cars, played an important role in shaping the evolution of GHG emissions. Since 1990, the increase in the number of light trucks has been more than three times greater than the increase in the numbers of the overall fleet of passenger on-road vehicles.

At the same time, there have been continual improvements in the fuel efficiency of both passenger cars and light trucks over the last few decades. However, these improvements were not sufficient to offset the increases in emissions due to the change in composition of the vehicle fleet.
