Plans to reduce airline CO2 emissions using jet fuels made from waste wood have been called a "pipe dream" by environmentalists who have accused the industry, especially in the Montreal, of not adopting meaningful standards, despite a goal set by the International Civil Aviation Authority to cut aviation emissions to half of 2005 levels by 2050. Critics say that around 170 large scale bio-refineries would need to be built every year between 2020 and 2050, costing a prohibitive $60bn a year. At $3 per gallon, the green fuel would be more than double the current market price of petroleum-based jet fuel.
