Overconsumption of lithium
Lithium mining pollutes: it produces a huge amount of waste that kills all forms of life in soils and rivers if not reprocessed. Lithium mining is costly for the planet. To use lithium in lithium batteries, cobalt and other earths are also needed, which are only found in a few countries where they are easy…

Hydrogen-powered aircraft
Which is better, the plane or the train? The plane pollutes more, but it’s faster, more convenient and cheaper than the train. Trains are expensive in terms of infrastructure and space: stations, rails, track maintenance, etc. Oil lobbies compete with nuclear lobbies. Yet aviation and ecology can be reconciled. Hydrogen-powered aircraft pollute less than trains.…

Free public transport
Free public transport can be a way of getting more people to use it, and of developing it further. This enables us to fight pollution, limit road infrastructure, limit the use of cars and thus ease traffic congestion, give greater independence to young people, the elderly and others who can’t get around by car, and…

Zero emission transport
Producing hydrogen by electrolysis of water using various primary sources of carbon-free energy (wind, sun, water) could prove useful for trucks (which contribute 25% of CO2 emissions in the transport sector), public transport and boats. Unlike electric cars, which consume lithium, the use of which is harmful to the environment, hydrogen produced by electrolysis of…
