T-1A1c-A-4 - Gas buses
Definition¶
This emission source is defined by the IPCC in E-1A3b - Road Transportation.
Sustainability Category: Amber¶
This activity currently has moderate climate impact but may be necessary for urban functioning, with a clear pathway to decarbonization. While not yet climate-positive, this activity is actively improving the emissions profile and represents intermediate performance on the path to sustainability.
Transition Elements¶
This activity has the following mitigation options modelled as transition elements:
- T-1A1a-TE-15 - Shift to travel by gas bus
- T-1A1c-TE-2 - Biofuel for gas buses
- T-1A1c-TE-4 - Improved bus engine technology
Activity Model¶
This emission source is modelled with Combustion as:
