Transportation generates two types of impacts that contribute to climate change; one local, which affects air quality, especially in cities where pollutants are trapped, and the other, global, a consequence of greenhouse gas emissions from engine combustion.
The transition to decarbonized mobility requires specific cost-efficient measures for each type of transport (light land, heavy land, rail, maritime, and air), which should not be based on one, single technology.
There is a range of more or less mature technological solutions that can and should coexist to ensure a rapid reduction in emissions from the very start.
