You are free to choose your examples. These could be a company’s CSR commitments and practices, a comparison between CSR policies, a controversial case (BP Spill, Coca Cola’s water stewardship, Starbucks tax avoidance…) I recommend to choose a maximum of one or two examples (two might be appropriate if you want to propose a comparison between, for instance two CSR policies). You might also want to choose your example or case from a business sector you know better.
