Questions remain as to whether other countries' success with biofuels can be replicated in Africa, says Barry Muckle.

Biofuels and carbon capture, two of the most favoured methods for sustainability, are a 'catastrophe for humankind', argues David Hill.

There are good and bad biofuel programmes, and we would do well to distinguish between them, says Steven Savage.

Biofuels have tremendous potential, but there is a danger of policy leaping ahead of the science, says Jeff McNeely.

Higher food prices due to biofuels will benefit the rural poor — it's the urban poor who will lose out, argues J. H. Tim Williams.

The biofuel industry needs to highlight the effects of biofuel production on water availability, says Mike Baker.
