Task 4: Global environmental issues Option 1: You are working in the UN Secretary General's team. You have to prepare a briefing paper for the SG on how the concept of global public goods or regional public goods can be used to promote international co-operation by a small group of countries such as in East Africa or West Africa or Southern Africa. Use arguments in Kaul et al, 1999, Anand, 2004 and Sandler, 2020 to support your arguments. Option 2: Write a critical commentary on the COP26 and compare it with the literature on COP15 (Copenhagen) and COP21 (Paris). In your assessment has COP26 been a success or a mere hype? If you were involved in advising the British Prime Minister what would you have done differently? Support your arguments with literature on COP15 and COP21 and also Scott Barrett's book Environment and Statecraft
