Biofuels needed but some more polluting than fossil fuels, report warns

Royal Academy of Engineering report backs increased use of biofuels but says more should come from waste rather than food crops

Biofuel use needs to increase to help fight climate change as liquid fuels will be needed by aircraft and ships for many decades to come, finds a new report requested by the UK government.

The Royal Academy of Engineering report says, however, that some biofuels, such as diesel made from food crops, have led to more emissions than those produced by the fossil fuels they were meant to replace. Instead, the report says, rising biofuel production should make more use of waste, such as used cooking oil and timber.
