You must first understand what CSR is. Please surf the Internet or visit HR sites to gather this information initially. In simple terms, corporations have a responsibility to fulfill towards society and stakeholders. They acquire many inputs from society to operate their business and generate profits. As a result, they should contribute back to society.
Once you grasp the concept and draft a document, the senior team will review it and provide valuable input.
Good luck.
