Greenhouse gas emissions from biofuels such as palm oil, soybean and rapeseed are higher than those for fossil fuels when the effects of Indirect Land Use Change (ILUC) are counted, according to leaked EU data seen by EurActiv.

The default values assigned to the biofuels compare to those from Canada's oil sands - also known as tar sands - according to the figures, which should be released along with long-awaited legislative proposals on biofuels in the spring.

A spokesperson for the European Commission said she could "not comment on leaked documents, such as impact assessments which have not been published."
