I think you should start by doing research on the organization. The web site would help. See what kinds of programs they have in place, and if you agree or disagree with what they are doing. You might include suggestions for how they could do better also.
I really think that you need to narrow down your question. UNEP (I assume you are referring to the UN Environment Programme) does so many things that it is hard to talk about its role in a generic sense.
For example, do you want to talk about whether its actions actually help developing countries become stronger economically? Do you want to talk about whether its actions actually help the environment? Do you want to talk about whether it is a way for the developed world to try to impose its values on the developing world?
Any of these questions could be the basis for a project. Please clarify your question so that we would be better able to help you.
