Two experts at Friedrich Schiller University in Jena say eight out of their 10 tests on locally produced rapeseed biodiesel failed to show the 35% greenhouse gas savings promised. In most cases it was under 30%. The use of biofuels would be further undermined when the EU emissions target increases, as planned, to 50% in five years' time.
Gernot Pehnelt and Christoph Vietze also claim their work has been undermined by a lack of co-operation from the European Union which they believe is on the defensive over championing local energy crops.
Le débat déjà houleux sur les biocarburants devrait s’intensifier : des chercheurs allemands affirment détenir des preuves que le biodiesel produit en Europe n’atteint pas ses objectifs de développement durable, contrairement à ce que Bruxelles affirme.
