Boeing Co. is working with US regulators to approve fuel jets
that include green diesel, which is made from
vegetable oils and fats. This move will reduce consumption of
fossil fuels and curb greenhouse-gas emissions.
The new jet fuel produces less than half the carbon dioxide
emissions over its life cycle than fossil fuels and will cost
about US $3/gallon, Chicago-based Boeing said in a statement.
Approval to use a fuel made from vegetable fats would
increase options for airlines that are already using other
types of biofuels made from inedible plant material.
Existing refineries that mostly supply the trucking industry
in the US, Europe and Singapore may provide as much as 600
million gallons (2.27 billion liters) of the fuel for jets
annually, or about 1% of global aviation demand, according to
The European Union is encouraging airlines to buy cleaner
fuels with a cap on greenhouse gas emissions. Aviation
accounts for about 2% of the global carbon-dioxide emissions.
