EPA decision delayed further
The Obama administration has further delayed its decision on whether to lower the amount of ethanol contained in the US's fuel supply.
After months of delay, a final decision was due to be delivered by the end of the year, but the Environmental Protection Agency (EPA) has confirmed that this will not be made until 2015.
In 2014 the EPA suggested reducing the amount of ethanol in fuel for the first time, admitting that regulations made in 2007 were not operating effectively.
