Subject: The context in which alternative energy consumption will intensify to fight climate change led this report to consider the carbon footprint of biofuels in terms of greenhouse gas emissions. Are biodiesels and bioethanols - which are today compulsorily incorporated into petrol by the TGAP (general tax on polluting activities) that is fixed by the (French) government - sustainable solutions to reduce CO2 emissions? This work, produced through precise scientific methodology, shows the diversity of biofuels and the complexity required to evaluate them.
