Biodiesel worse for the environment than fossil fuels, warn green campaigners
Instead of reducing levels of pollution, the use of biodiesel in transport will increase emissions by 4% - the same as putting an extra 12 million cars on the road in 2020 - green campaigners have said.
Biodiesel is touted as one way to decarbonise the EU’s transport sector. But, according to NGO Transport and Environment (T&E), using it is actually worse for the environment than traditional fossil fuels.
Transport is responsible for around a quarter of the EU’s greenhouse gas emissions, making it the second-biggest emitting sector after energy.
It is the only major EU sector where emissions today are well above their 1990 levels, making its decarbonisation vital if the EU is to hit its climate change goals.
T&E’s analysis builds on the long-delayed and controversial Globiom study, that was finally published last month.
Critics have accused the European Commission of keeping the study, which was commissioned in 2013, under-wraps until the consultation period for the review of the Renewable Energy Directive (RED) was over.
Jos Dings, executive director of Transport & Environment, said: “The European Commission has finally revealed that Europe’s policy failure in stimulating bad biofuels is even more spectacular than previous scientific research indicated.”
A consortium of three respected research institutes, including Ecofys and IIASA and e4Tech, wrote the study.
But the findings were denied by Raffaello Garofalo, the secretary general of the European Biodiesel Board, an industry group, who branded the study “unreliable”.
“We are quite surprised by the biased campaign set-up by T&E,” said Garofalo who accused T&E of lobbying “against biodiesel and in favour of fossil fuels.” A graph released by T&E indeed shows fossil fuels emitting less than rapeseed, soy or palm oil.
Vegetable oils from crops such as palm, rapeseed and soy are blended with fossil diesel to create biodiesel.
But those three crops cause direct and indirect land-use change (ILUC) emissions when new or existing cropland is used for biofuels instead of food, according to the study.
Those emissions alone exceed the full lifecycle emissions of fossil diesel, according to T&E.
ILUC is a way of measuring the impact of the displaced agriculture being moved to grasslands and forests, which absorb high levels of global warming CO2. Turning such carbon sinks into crops increases the CO2 in the atmosphere.
T&E took the findings of the study, added the direct emissions of biofuels from, for example, tractors and fertilisers, and subtracted the emissions from the alternative fossil fuel.
It found: -
- On average, biodiesel from virgin vegetable oil leads to around 80% higher emissions than the fossil diesel it replaces;
- Soy and palm-based biodiesel are two and three times worse respectively. This biodiesel is the most popular biofuel in the European market and is forecasted to have an almost 70% share in 2020;
- In total more than three-quarters of biofuels, which includes bioethanol as well as biodiesel, are forecast to have lifecycle greenhouse gas emissions similar or higher than fossil petrol and diesel in 2020.
The EU reformed its biofuels policy last year, capping the contribution of food crops to biofuels at 7%.
T&E took the cap, which was revised up from the Commission’s proposed 5% in talks between the European Parliament and Council, into account in their analysis.
Renewable Energy Directive
But ILUC emissions are not included in the carbon accounting of biofuels under the RED, currently under review with fresh legislation expected before the end of the year, and Fuel Quality Directive.
This means that ILUC-causing biofuels count towards the EU’s 2020 RED target, and can be eligible for public money at national level.
By 2020, 10% of energy used in transport in each member state has to be produced from renewable energy sources, such as biofuels, biogas, electricity or other renewable sources.
Dings said, “The cure is plainly worse than the disease. The 7% cap on food-based biofuels has helped though, and should be lowered to zero after 2020.
“If we do not end incentives for bad biofuels, the better ones will not stand a chance.”
But the EBB’s Garofalo attacked the GLOBIUM study, saying it does not represent the views of the Commission, although it was funded by it. “By ignoring the lack of credibility of the GLOBIOM modelling, and calling for a 0% cap on first-generation biofuels after 2020, T&E is actually advocating for more fossil fuels in road transport,” Garofalo said.
Rather, Garofalo prefers referring to another model developed by the California Air Resources Board (CARB), which he said was a more reliable, “open and peer-reviewed process”. CARB is the same agency that investigated recent cars’ emissions rules violations in the US.
“The CARB ILUC model is an open and peer-reviewed process, which resulted in ILUC values for biodiesel that are four to five times lower than those found by the GLOBIOM study,” Garofalo said.
