Greater aviation biofuel use would thus further push up the global demand for vegetable oil. Whether directly or, via price mechanisms, indirectly, this would push up the price of palm, soybean and canola oil and thereby make land conversion, particularly in the tropics even more lucrative. At least as harmful, however, is the fact that the hype around aviation biofuels is being used to legitimise continued growth of aviation. Only a tiny proportion of the world’s population will ever step on a plane, yet global aviation emissions far exceed the total greenhouse gas emissions of most countries. If we want to avoid the worst impacts of climate change, there is no alternative to drastic curbs on aviation.
