George Monbiot wrote about the carbonisation of organic matter in the Guardian last month (‘Woodchips with everything. It’s the Atkins plan of the low-carbon world’, Tuesday 24 March 2009), saying it was yet another miracle cure for the climate problem. And, like previous miracle cures, he said ‘biochar’ would turn out to be a dangerous delusion. It would deflect attention from taking real action on climate change. Parts of the planet would be turned into vast forest plantations with limited biodiversity to provide feedstock for huge factories. Vital food-growing land would be lost to vast corporations farming wood for turning into biochar. It is a re-run of the biofuels disaster, he said.
