What could be more environmentally harmful than fossil fuels? Try biofuels. That’s right, a new study claims that we’ll make global warming even worse if we rely too much on the new generation of biofuels, because rules governing their production encourage deforestation. And, as another recent report illuminated, our forests are our most important line of defense against climate change.
From Reuters:
In a study to be published Friday in the US journal Science, a group of 13 scientists called for the rules, which contain a loophole exempting carbon dioxide emitted by bioenergy regardless of its source, to be overturned.
“The error is serious, but readily fixable,” said lead researcher Timothy Searchinger of Princeton University.
The study called for the issue to be addressed in the climate treaty that nations around the world are hoping to sign at the Copenhagen summit in December to supercede the Kyoto Treaty.
Researchers said numerous analyses — including one released by the US Department of Energy — have found that this loophole “could lead to the loss of most of the world’s natural forests as carbon caps tighten.”
The loophole needs to be closed before oil companies, power plants and other energy industry firms – who stand to benefit the most from it – can exploit it.
But that’s not the only problem with biofuels. Another study published in Science Express on Thursday noted that there’s not enough oversight on land use when it comes to producing biofuels, meaning some unscrupulous companies could cut down forest lands and use them to grow fuel.
Burning biomass releases almost as much carbon dioxide as burning fossil fuels, but that CO2 is partially offset by the plants themselves, grown for biofuel, absorbing CO2 from the air. That’s a big benefit – but we can’t cut down forests to grow these plants. Talk about counterproductive.
