The project's primary purpose was also to produce a study with a comparative analysis of the tools, methodologies, and legislative framework already in use in other European countries and Greece for the process of participation of women in the economic decision-making centers of listed companies. The tools and methodologies were gathered for analysis and processing with the ultimate goal of comparing their effectiveness towards gender equality in financial decision-making centers. Also, best practices in European countries that promote gender equality in companies will be recorded and highlighted. The current state legislation on this issue was analyzed, and a comparative analysis of the different legislative frameworks was made based on their results in terms of gender equality. There has also been a self-assessment tool for listed companies for the policies they apply, in line with corporate governance principles, to promote women in high positions at the economic decision-making level. This tool was an online software application for data processing and dynamic reporting, and statistical metrics.
