A new package of laws drafted by the European Commission aims to reduce consumption of fossil fuels within the European Union.
Called "Clean Energy for All Europeans," the plan calls for emissions reductions in both the transportation and energy sectors, as well as increased use of renewable energy for electricity generation, and biodiesel for transportation fuel.
But the plan is being heavily criticized from multiple directions.

Both the auto industry and at least one environmental group are slamming the European Union plan, for different reasons, according to Wards Auto.
The plan includes provisions that EU members generate at least 27 percent of their electricity form renewable sources, and develop transportation fuels that produce at least 70 percent fewer emissions than fossil fuels.
The European Commission hopes to achieve the transportation-fuels target in large part from biofuels that aren't made from crops used for food.

It proposed capping the amount of food-based biofuels used to meet the target at 7 percent in 2021, and reducing it to 3.8 percent in 2030.
At the same time, it would raise the share of "advanced biofuels and renewable-transport fuels" from 1.5 percent in 2021 to 6.8 percent in 2030.

The minimum share for advanced biofuels would also increase from 0.5 percent to 3.6 percent over the same period.
Automakers are not opposed to increased deployment of biodiesel, but they are concerned that the definition of "advanced biofuels" in the European Commission plan leaves room for too wide a variety of feedstocks.
Fuels that contain fatty-acid methyl ester (FAME) can clog fuel filters, especially in cold weather, said the ACEA, a trade group that represents European automakers.

Meanwhile, environmental group Transport & Environment believes the European Commission should focus less on biodiesel, and more on electric cars.

The group criticized the European Commission for "favoring unproven biofuels over clean electricity for transport."
T&E called for a target based on a specific level of greenhouse-gas emissions to promote cleaner fuels, as well as a renewable-electricity generation target, and targets for individual types of biofuels.

One proposal already made would require commercial buildings with more than 10 parking spaces to have electric-car charging stations by 2025.
However, an earlier draft had the deadline at 2023, and T&E notes that the proposal says nothing about charging stations along highways and at public places in urban areas.
