I am mostly interested how this will be implemented.

How do you isolate differences that may arise due to different individuals being of different value to the company for one reason or the other.

Indeed. If you equalise pay between men and women, then either (a) you have to equalise pay among all employees for the same work, or (b) you throw merit-based salaries out the window and mandating paying more to one gender than the other for the same work.
