Are Biofuels a solution ?

Biofuels are essentially renewable energy sources that could substitute fossil energy.

Produced from grain or sugar beet crops in the case of ethanol and ethyl tertiobutyl ether (ETBE), or from oil-bearing plants such as rapeseed and soybeans in the case of oil methyl esters, biofuels are essentially renewable energy sources that could substitute fossil energy. In addition to their substantial contribution to mitigating the greenhouse effect, these fuels offer environmentally friendly performance, notably by reducing particulate emissions.

PSA Peugeot Citroën strongly encourages substituting 30% rapeseed methyl ester for diesel fuel. The Group's diesel fleet already runs on RME. To increase gasoline octane ratings without lead derivatives or aromatic hydrocarbons, the Group recommends using 8 to 12% ETBE derived from bioethanol.
PSA Peugeot Citroën has made biofuels one of its main avenues of research.
