M-1A-3 - Public Transit
Public transit, also known as public transportation or mass transit, refers to a system of transport services available for use by the general public. These services typically operate on set routes and schedules, and are designed to move large numbers of people efficiently.
Public transit is outlined in sections 10.2.2 (shift: mode choice for urban and intercity transport) and 10.4.2 of (IPCC AR6 WG3 2022)1.
Mitigation Objective¶
The primary goal is for a shift from light-duty vehicles to public transit alternatives for short and medium journeys (25km or less).
Mitigation Potential¶
Potential
The AR6 report and the literature referenced by it do not present any reliable estimates for the mitigation potential of a shift to public transit.
A shift to public transit modes can likely offer significant emissions reductions, but estimates are uncertain.

Modelling¶
This mitigation method has been modelled with the following Transition Elements:
- T-1A1a-6 - Transfer from car to railway
- T-1A1a-12 - Increased proportion of commuting by electric bus
- T-1A1a-16 - Increased proportion of public transport by petrol bus
- T-1A1a-17 - Increased proportion of public transport by diesel bus
- T-1A1a-18 - Increased proportion of public transport by Trams and Light Rail
Primary Reference¶
The primary reference for this mitigation measure is (IPCC AR6 WG3 2022)1.
Secondary References¶
No relevant secondary references have been identified.
