The draft also speaks about the (in)convenience of using biofuels to counteract global warming, something the EU is already aware of. On the topic of biofuels and their CO2 balance, the draft states that nitrogen fertilizers, as well as deforestation, could offset any carbon reduction.
There's also a section dedicated to "energy independence" and "jobs creation," two of the most common arguments to support biofuels. For the first, the draft states that it's better to "invest in a strategic oil reserve for the short term, instead of investing a higher amount of money in agrofuels which would yield less energy". Regarding jobs, the impact is considered "insignificant". However, not all of the JRC's arguments are against biofuels. The draft also says that biomass is a good source to produce energy.
As a final conclusion, this draft proposes a complete approach to address global warming from all fronts, instead of focusing only on transport emissions and costs.
