Study: Biofuels Release 420x More CO2 Than is Saved

Earth (TGW) – A new study by The Nature Conservancy shows that biofuel can release 17 to 420 times more carbon dioxide than the annual greenhouse gas reductions these biofuels provide by displacing fossil fuels.


The study shows that it depends where the biofuels are grown and what they are made from.

For example, converting rainforests, peatlands, savannas, or grasslands to produce food-based biofuels in Brazil, Southeast Asia, and the United States creates more carbon dioxide than is saved.

In contrast, biofuels made from waste biomass or from biomass grown on abandoned agricultural lands planted with perennials incur little or no carbon debt and offer immediate and sustained advantages.
