European Parliament, BrusselsThe European Parliament called for a cap on the use of traditional biofuels and a speedy switchover to new biofuels from alternative sources such as seaweed and waste, in a vote on draft legislation yesterday. So called “first-generation” biofuels – from food crops – should not exceed 6% of fuel used in transport by 2020, amending the target from 10%.The measures aim to reduce greenhouse gas emissions that result from the increasing turnover of agricultural land to biofuel production.
