Are biofuels doing more harm than good? It is a question that stays on the agenda, and I ask my readers to provide their views and facts. This week’s discussions at Doha remind us that tackling climate change can be as complex as it is important.

One such complexity relates to the unintended, negative consequences of well-intended solutions such as biofuels - one of the most divisive and controversial environmental policies.

This is a subject that I have written about several times before on this blog and one that I will be debating next week at the European Parliament during a high level discussion organised by the International Institute for Sustainable Development.
