T-1A1a-TE-4 - Improved car engine technology
Background¶
IPCC WG3 definition: M-1A-15 - Improved Energy Efficiency for Vehicles.
Improved vehicle and engine technology - as well as reduced vehicle weight - can reduce emissions from fossil-fueled cars. This shift can help reduce emissions in the short term, until e-mobility and other zero-emission transport modes reach their full potential.

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.
