T-1B3-A-2 - Freight air transport

Definition

This emission source is defined by the IPCC in TBD.

Sustainability Category: Red

This activity significantly contributes to greenhouse gas emissions and undermines climate mitigation efforts. The activity should be phased out or fundamentally transformed, with financing directed toward decommissioning, replacement with sustainable alternatives, or radical decarbonization where elimination is not immediately feasible.

Transition Elements

This activity has the following mitigation options modelled as transition elements:

• T-1B3-TE-1 - Biofuel for kerosene air freight transport
• T-1B3-TE-2 - Shift to electric freight air transportation
• T-1B3-TE-3 - More efficient air freight transport
• T-1B3-TE-4 - Shift from freight air transport to electric rail freight
