The increase in CO 2 production by the automotive sector has led to an increase in work towards new technologies that reduce their contribution to pollution, such as electric cars, hybrids and the use of fuels obtained from renewable sources or biofuels.This study has focused on the production of biofuels because it is the first renewable option for cleaner combustion because it significantly reduces carbon emissions.Because of this, the PES analysis looked at the reasons why this large difference occurs.The first review was of state regulations governing biofuel production in the three countries studied.The USA and People's R China have clear policies and very consistent goals accompanied by investments and tax extensions and these policies were compared with those implemented by Colombia to have a measure of how far this country is from the world powers in terms of biofuel production.
