The notion of development must take a turn away from fossil fuels, but to achieve this, both developed and developing countries have to pull their respective weights and uphold a “common but differentiated responsibility”. But what does this really mean? In the second episode of COP21, we discuss the conflicting interests of the developed and the developing world, particularly with regard to this year’s talks. Joining us for this debate are Professor Gurdial Singh Nijar, Malaysian Negotiator for the Paris talks and lead spokesman for Like Minded Developing Countries (LMDC) and His Excellency Christophe Penot, Ambassador of France to Malaysia.
