Motor vehicles circulate to meet the mobility needs of the population and the economy.
They generate environmental burdens during their use, but also and above all during their manufacture and recycling, as well as during the production and distribution of the fuel or electricity they consume. These loads are exerted on the places of use of the vehicle, as well as on the places in which it was manufactured or will be recycled, or in which the energy which it consumes is produced or distributed. They come under different environmental areas: CO2 emissions, polluting emissions, damage to nature and landscape. Their intensity varies depending on the propulsion technology and the type of fuel or electricity used.
In addition to the environmental burdens they generate, motor vehicles also have a significant impact on the use of exhaustible resources.
The table below shows the expected reduction in impacts on the environment and resources that will allow by 2040, compared to the situation in 2010, different propulsion technologies for vehicles: battery electric (with shares of renewable electricity 20, 50 and 80%) and classic combustion (with conventional or hybrid transmission), as well as a sustainable alternative taking advantage of the synergies achievable between a heat engine with high efficiency and effectiveness, clean fuel and a lightweight and long life vehicle cell.
Of all the technologies examined is the sustainable alternative, based on a thermal eco-engine and a synergistic propulsion, the most favorable for the climate and the planet, the most economical in resources, the one which best meets the needs of the population and the economy of the different regions of the world, and the one that could be fully implemented most quickly. It is therefore the essential condition for sustainable mobility.
