A report from the University of Oxford entitled Future of mobility roadmap suggests that the best way to curb carbon dioxide (CO 2 ) emissions in the short term is to reduce the size and weight of cars .
David King, study leader, and his colleagues have taken a deep look at the future of trucking. And they have come to the conclusion that if they want to reduce the emissions that cause the greenhouse effect, electric and hydrogen vehicles are not going to achieve it immediately , since there are still technical and supply limitations for their massive use. For this reason, they recommend that governments increase taxes on large and energy-inefficient vehicles , and reinvest the money collected in improving public transport and promoting transport by bicycle and walking. "But first you have to convince consumers to acquire new habits," they say.
The report also highlights the use of biofuels obtained from algae , although it reminds that the availability of these ecological fuels will be limited. And he stresses that replacing the majority of domestic flights in countries like Great Britain with high-speed train travel would also mean a drastic reduction in pollutant emissions.
