Once you have identified a company you wish to analyze for how well they comply with the principles of the UN Global Compact, use a database called BUSINESS SOURCE COMPLETE (screenshot shown below) to search for articles on the company. For example, I have selected the pharmaceutical company Merck.
On the first line, use the drop-down arrows to target you search, plus some alternate terms that get at the issue of corporate responsibility.
On the 2nd line, use synonyms for CSR. This will generate a list of articles discussing how well Merck complies with socially responsible behavior. Other synonyms you might use include UN Global Compact, social justice, etc.
