for petrol engines. Similarly, the unit consumption of heavy goods vehicles and buses and coaches is falling. The new National Low Carbon Strategy provides for all sectors to achieve carbon neutrality by 2050 (national greenhouse gas emissions must be lower than the quantities of greenhouse gases absorbed by the natural environments managed by the man and to those captured by processes industrial). By this time, it is expected that the transport sector will no longer emit any GHGs (excluding air transport). Emissions from the transport sector must fall within the decarbonization trajectories set by SNBC-2 (2nd version).
