Direct emissions in the transport sectors

In transport, direct emissions refer generally to emissions occurring during travel. They depend mainly on :

• the transport modes (road, rail, inland waterways, aviation, maritime transport, etc.),
• the energy sources (gasoline, diesel, electricity, natural gas, etc.)
• and the technologies used to travel,
• the behaviour of the drivers (if any) and other influencing parameters such as meteorological conditions, the age and the maintenance of the vehicle, etc.
