The electrification of private cars is not enough to decarbonize mobility.

Despite their environmental advantages, electric vehicles come with several constraints and challenges, including the extraction of lithium, which raises ethical questions. Electric cars alone are not able to solve urban problems such as traffic jams or bus delays.

To ensure the success of electrification, we should use our limited resources to optimize shared fleets, rather than individual cars. For example, we have conducted research that suggests that the electrification of taxi fleets can help reduce carbon emissions, and therefore offer an alternative solution to private cars.

Electrification is proving more effective for public transport than private cars: electric buses, hydrogen buses, electric railways, etc. Public transport is therefore the key to decarbonizing mobility.
