T-1B4b-TE-2 - More efficient marine freight transport

TBD

Background

IPCC WG3 definition: .

Improving the energy efficiency of ships, for example through the use of lighter materials and more efficient engines, reduces the emissions per transport work performed.

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.

Transition Element

Shift type: Efficiency Shift
Operations: tonne_km
Activity measure: tonne_km
