Budgeting of climate consequences of biofuels

Ecological budgeting of bioethanol and biodiesel covers a wide range of GHG emissions according to the specific conditions on site. Figure 13.7 represents the results of a literature survey (Bauen, 2005). The difference between biofuels and fossil based petrol or diesel is displayed. Maximum and minimum values are given; GHG emissions of actual cases would lie between the two extremes.

In general the results elucidate that the GHG emissions range is between negative values and more than 100 percent improvement. Negative values indicate that more GHG emissions would occur compared to fossil fuel production. A value of more than 100 percent means that not only the GHG emissions from fossil fuels are compensated but a bonus results from benefits of by-products such as renewable energy generated during fuel production. In some cases there is more energy transformed into power than into resulting biofuel.
