T-1A4-TE-2 - More efficient marine passenger transport

Background

IPCC WG3 definition: M-1C-3 - Improved Energy Efficiency for Shipping.

TBD

Sustainability Category: 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.
