I'm thinking to do research related to UN's SDGs. Could you suggest some ways to measure SDGs disclosure in the annual reports of the listed companies?
The effective monitoring of SDG indicators requires comprehensive national health information strategies based on the use of data from sources such as civil registration and vital statistics systems, household and other population-based surveys, routine health-facility reporting systems and health-facility surveys.
I would also suggest to do a content analysis of the annual reports (you can refer to Mayring's works as introductory literature on that).
As for some further tips, please keep in mind that analyzing qualitative data, such as long textual documents in this case, is generally really time-consuming and the establishment of truly objective measurement criteria is rather hard from my personal experience. There is also no "one right way" to do a content analysis since it all depends on the research context, so you will most likely have to tailor your approach to your specific project. In short, a good preparation and a logical research design are the most essential attention points for you.
I wish you good luck and all the best on starting your interesting project,
