In a study published by Science, it was found that advanced biofuels such as woods and grasses that are meant to provide alternative fuels without cutting into food supplies (such as ethanol does), will emit more carbon dioxide than burning gasoline over the next few decades .. and yes also cut into food supplies. The study concludes that the land required to grow poplar trees and tropical grasses will displace food crops and accelerate deforestation. Why is this so difficult for governments to understand? Another study published last week in the journal Science also indicates that the UN has exaggerated the carbon savings from biofuels because it ignores deforestation and other land use costs.
also published in the journal Science on Thursday, said the United Nations had exaggerated carbon savings from biofuels and biomass, in a mistake copied by the European Union in its cap and trade law, by ignoring deforestation and other land use changes.
