T-1A1 - Road
The road sub-sector encompasses a wide range of transport modes, including light-duty vehicles, two- and three-wheel vehicles, and buses, all of which play a vital role in everyday transportation for people across the globe. This sector is a significant contributor to greenhouse gas emissions, making it a critical focus for climate mitigation efforts.
The strategies explored below aim to reduce emissions through - for example - the adoption of cleaner fuels, the development of more efficient vehicles, and the electrification of various transport modes. By advancing these technologies and promoting sustainable practices, the sector seeks to significantly lower its carbon footprint and contribute to global sustainability goals.
T-1A1a - Light Duty Vehicles¶
Personal and small-scale commercial vehicles, including cars, vans, and similar transport modes, which are a major part of daily mobility for many individuals. As a significant source of greenhouse gas emissions, this subsector is targeted by a wide range of mitigation strategies.
Key transition elements include the shift to electric and hydrogen vehicles, promoting eco-driving practices, and improving vehicle technology for greater efficiency. Additionally, strategies like remote working, non-travel meetings, and increasing the renewable proportion in petrol aim to further reduce the environmental impact of light-duty vehicles. Collectively, these initiatives work towards significantly lowering emissions and advancing sustainable mobility within the subsector.

T-1A1b - 2/3 Wheel Vehicles¶
Motorcycles, scooters, and similar modes of transport, are widely used for personal mobility, especially in urban areas. This subsector is targeted for emission reduction through two primary strategies: the adoption of biofuels as a cleaner alternative to conventional petrol for motorcycles and the shift to electric motorcycles.
These transition elements aim to lower the carbon footprint of two- and three-wheel vehicles, contributing to more sustainable and environmentally friendly urban mobility.

| | Index | Transition Element | IPCC Mitigation Option |
|---|---|---|---|
 |
T-1A1b-1 | Biofuel for petrol motorcycles | M-1A-11 - Alternative Fuels for Vehicles |
 |
T-1A1b-2 | Shift to electric motorcycles | M-1A-12 - Electric Technologies |
T-1A1c - Bus¶
Public and private bus transportation is a crucial component of urban and intercity mobility. To reduce the environmental impact of buses, this subsector explores the use of alternative fuels, specifically biofuels and biogas, as cleaner alternatives to traditional diesel and petrol.
Transitioning to these renewable energy sources aims to significantly lower greenhouse gas emissions from buses, contributing to a more sustainable public transport system and supporting broader climate mitigation efforts.
