FRANKFURT -- DaimlerChrysler pledged on Thursday to help promote the use of biofuels by developing engines that can run on higher mixtures of the alternative energy sources.
"DaimlerChrysler is committed to creating the technologies that will ensure vehicles can run on fuels with up to 10 percent admixtures of biodiesel or bioethanol," it said after meetings with the United Nations Environment Program.
"Until now, it has been possible to fill up with fuels with a 5 percent admixture content," it added in a statement.
It also promised it would work with other automakers and oil companies to lobby for adjusting fuel standards and creating incentives to promote biofuels.
Biofuels based on such common commodities as rapeseed oil and sugar cane are growing in popularity in Europe as countries try to cut greenhouse gas emissions -- blamed for global warming -- and crude oil import bills.
The European Union has set a non-binding target of 5.75 percent biofuel content by 2010.
