European lawmakers limited the use of biofuels to 6 percent of total transport fuel demand in the European Union by 2020.
The European Parliament voted on Wednesday to limit the use of fuels made from food crops, or so-called "biofuels."
The use of biofuels was originally posited as an alternative to traditional energy sources, but lately has come under fire for contributing to climate change and pushing up food prices.
Lawmakers in the European Parliament in Strasbourg, France, limited the use of the fuels to 6 percent of total transport fuel demand in the European Union by 2020, Businessweek reported.
That's a higher cap than the European Commission proposed last year, of 5 percent. But it's lower than the 10 percent once allowed under the EU's commitment to increasing renewable energy sources.
"First-generation" biofuels may eventually find themselves replaced by non-crop fuels made from algae or agricultural waste, Reuters said.
Biofuels like ethanol are made from foods like sugar and rapeseed, and are mixed with traditional fuels in order to reduce carbon emissions and reliance on oil.
Palm oil, which is also used, has been linked to deforestation in Asia.
The decision must still be approved by EU governments before it comes into law, the Wall Street Journal said.
