T-1A1a-A-2 - Diesel cars

Definition

This emission source is defined by the IPCC in E-1A3b - Road Transportation.

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-1A1a-TE-1 - Shift to electric cars
• T-1A1a-TE-2 - Shift to hydrogen cars
• T-1A1a-TE-3 - Ecodriving of cars
• T-1A1a-TE-4 - Improved car engine technology
• T-1A1a-TE-5 - Increase journey sharing
• T-1A1a-TE-6 - Shift from car to railway
• T-1A1a-TE-7 - Shift to online meetings and services
• T-1A1a-TE-8 - Shift from car to remote working
