  • Abstract:
    Emissions of short-lived species contribute significantly to

    the climate impact of transportation. The magnitude of the effects

    varies over time for each transport mode. This paper compares

    first the absolute climate impacts of current passenger and

    freight transportation. Second, the impacts are normalized with

    the transport work performed and modes are compared.

    Calculations are performed for the integrated radiative forcing

    and mean temperature change, for different time horizons

    and various measures of transport work. An unambiguous

    ranking of the specific climate impact can be established for

    freight transportation, with shipping and rail having lowest and

    light trucks and air transport having highest specific impact

    for all cases calculated. Passenger travel with rail, coach or twoand

    three-wheelers has on average the lowest specific

    climate impact also on short time horizons. Air travel has the

    highest specific impact on short-term warming, while on longterm

    warming car travel has an equal or higher impact per

    passenger-kilometer.
