I think two good databases are Asset4 ESG database and Bloomberg ESG database, which provide scores for the effectiveness of CG. Hence, you could benefit from Thomson Reuters EIKON as well, since it provides data for Board composition (Independent, Executive members, number of meetings etc.) and, to the best of my knowledge, covers emerging markets. Otherwise, the only way out is annual reports.
the only alternative for firm-level CG data is annual reports. Otherwise, a common practice is to approximate governance using world bank governance indicators, available at country level. I hope this helps and good luck with your data collection and analysis.
You can get most of the information you need from the annual report. If you can get in touch with regulatory bodies like Securities and Exchange Commission they will be able to provide you with copies of previous year’s annual report. The only problem is that you will have to transport the data from Word to Microsoft Excel. Regarding corporate governance some countries do have code of corporate governance for banks or banking laws that guides banks, which are available and easy to access online.
