CO2e emissions per passenger- kilometre (gCO2e/pkm).
Zero direct emissions land transport activities (e.g. light rail transit, metro, tram, trolleybus, bus and rail) are eligible.
Other fleets are eligible if direct emissions are below 50 gCO2e/pkm until 2025 (non-eligible thereafter).
Zero direct emissions public transport (e.g. electric, hydrogen) is eligible because:
• With the present energy mix, the overall emissions associated with zero direct emissions public transport (i.e. electric or hydrogen) are among the lowest compared with other transport modes.
• The generation of the energy carriers used by zero direct emissions transport is assumed to become low or zero carbon in the near future.
The threshold of 50 gCO2e/pkm until 2025 ensures that the carbon intensity remains similar to criteria for eligible road vehicles with low occupation factor (50 gCO2/vkm) and significantly lower than emissions for an average car.
