Biofuel aim is 'greenwash'
Friends of the Earth Scotland said proposals to use bio- kerosene were an attempt by the aviation industry to continue "business as usual".
Stan Blackley, chief executive of FOE Scotland, said: "In a world where millions go hungry, it would be incredibly irresponsible to grow enormous amounts of new crops to fuel cheap flights and long-haul holidays for the richest in the world, rather to feed the hungry.
"Biofuels exacerbate poverty and hunger, drive people from their traditional lands, cause massive deforestation, and help to push up food prices."
