Emission factor from UBA (AT)

Domestic flight - Air

Austria · Energy, full life cycle · Any year

Each kilometre one vehicle drives counts as 30 kg CO₂e, including 27 from the fuel it burns.

Value per kilometre driven

30kgCO₂e/km

With radiative forcing · Biogenic CO₂ and land use excluded · GWP100 · AR5

One value, for any year

UBA (AT) sets no date window, so there is no year to pick.

Where 30 comes from

Σ 27: the parts published here make up part of the total open-climate.ai works out, 30.

Reporting this kilometre under the GHG Protocol

Scope 3, category 6

A trip for work is business travel, Scope 3, category 6, whoever books it.

What this number covers

The path of one vehicle-kilometre, from the oil well to the end of the trip.

  1. Fuel production

    Extracting, refining and delivering the fuel

    IncludedScope 3, cat. 6
  2. Vehicle operation

    Burning the fuel in flight, spread over the average load

    IncludedScope 3, cat. 627
  3. Effect at altitude

    Contrails and other warming from burning fuel high up. Flights only.

    Included
  4. Your trip

    1 km driven. The factor is per vehicle-kilometre.

    = 30

Outside this boundary

  • Airports

Vehicles and infrastructure sit outside every well-to-use factor. Some libraries price building the vehicle as a factor of its own.

Gases in vehicle operation

27

Basis: Excl. biogenic CO₂

  • Carbon dioxide (CO₂)13.449.5%
  • Rest, not split by gas Derived by open-climate.ai13.650.5%

The rest is not split by gas: open-climate.ai works it out as the 27 total less the gases UBA (AT) prints.

Each gas is converted to CO₂e with AR5 100-year warming potentials; biogenic CO₂ and land-use carbon are left out, while methane from biogenic sources is counted.

UBA (AT) splits the fuel burnt by gas; fuel production comes as CO₂e only.

From UBA (AT)'s record to a comparable factor

UBA (AT) publishes the three parts; open-climate.ai added them up to this total. Here is each field as printed and what open-climate.ai made of it.

The total and its parts

Use a part on its own when you report the fuel you burn separately from its production; never add a part to the total.

About this factor

From UBA (AT)

Where it applies

Translated from German
Note: Due to the change in the calculation system, a comparison with previous transport-mode lists is not permissible. For air transport, non-CO₂-Effekte are accounted for by applying a factor of 2.

Anmerkung: Wegen der Systemumstellung bei der Berechnung ist ein Vergleich mit vorangegangenen Verkehrsträgerlisten nicht zulässig. Beim Flugverkehr werden Nicht-CO2-Effekte durch die Anwendung eines Faktor von 2 berücksichtigt.
