This actually makes a lot of sense:

It sounds counterintuitive, but burning oil and planting forests to compensate is more environmentally friendly than burning biofuel.

So say scientists who have calculated the difference in net emissions between using land to produce biofuel and the alternative: fuelling cars with gasoline and replanting forests on the land instead. They recommend governments steer away from biofuel and focus on reforestation and maximising the efficiency of fossil fuels instead.

The reason is that producing biofuel is not a "green process". It requires tractors and fertilisers and land, all of which means burning fossil fuels to make "green" fuel. In the case of bioethanol produced from corn – an alternative to oil – "it's essentially a zero-sums game," says Ghislaine Kieffer, programme manager for Latin America at the International Energy Agency in Paris, France.
