As regards reducing greenhouse gas emissions from first-generation biofuels

الملخص EN

The development of biofuels responds to a need for energy sovereignty and the reduction of greenhouse gas emissions in the transport sector.

Presented as an alternative to fuels of fossil origin, these biofuels raise many questions, particularly with regard to their real environmental interest.

Also, this study aims to determine the reduction in greenhouse gas emissions achieved by first-generation biofuels compared to fuels of fossil origin.

To achieve the proposed objective, the Life Cycle Analysis (LCA) method was applied to ethanol and biodiesel from the USA and Brazil.

The study presented according to the IMRaD structure revealed that the first generation biofuels produced in the USA and Brazil have greenhouse gas emissions lower than those of fossil fuels by 74 to 82% for ethanol and 49 to 51% for biodiesel.
