American biochemists want to power airplanes with soya oil to help reduce consumption of petroleum fuels that are driving global warming.

By adding a certain amount of soya oil to jet fuel, planes will slow the increase in emissions of carbon dioxide (CO2), the principal culprit for the greenhouse effect.



A meeting of the American Chemical Society in Anaheim, California, next week will be told how this can be done, the British weekly says.



The C02 in fossil fuels — oil and its derivatives, as well as gas and coal — has been stored underground for millions of years. So when the fuel is burnt, the CO2 adds to atmospheric pollution.
