Converting land for biofuel worsens global warming

February 7, 2008

we know that biofuel is a pure smoke strategy to go green…and just a PR for Big agro business industries

Biofuel

i love this new study about biofuel. check this extract:

"Global agriculture is already producing food for six billion people. Producing food-based biofuel, too, will require that still more land be converted to agriculture."

Converting land to grow corn, sugar cane or soy beans — crops used in the production of biofuels — creates a "biofuel carbon debt" by releasing 17 to 420 times as much CO2 into the atmosphere as the greenhouse gas reductions which the biofuels provide by displacing fossil fuels.

Carbon is stored in dead trees and plants as well as in the soil, and naturally seeps into the atmosphere in the form of CO2. Converting native habitats to cropland increases the release of CO2 into the air, the report said.

It would take years, and in some cases centuries, before biofuels derived from crops on converted land would lead to a net reduction of greenhouse gases, according to the report.

The researchers calculated that in Indonesia, where wetlands are being converted to grow palm oil to produce biofuels, it will take 423 years before biofuel CO2 emmission savings would repay the carbon debt caused by the land conversion.more

The Opportunity

Our reliance on fossil fuels has reached a tipping point. As energy costs and volatile oil prices impact operational business costs, governments look for safer energy supply and consumers push industry for clean energies and less air pollution for their children.
