T-1B3-TE-3 - More efficient air freight transport

Background¶

IPCC WG3 definition: .

TBD

Sustainability Category: Amber¶

Amber

This transition element has only moderate climate impact but may be necessary for maintaining urban needs, with a clear pathway to decarbonization. While not aligned with net-zero targets, this transition element is actively improving the emissions profile and represents intermediate performance on the path to sustainability.
