The enduring European gender imbalance has led Norway to mandate that 40% of directorships go to women — a legal quota that other governments also are rolling out. It's not going to happen organically. A comparison of surveys indicates that women make up less than 9% of boards in France's leading firms, compared with about 12% in the U.K., 13% in Germany and 8% in Spain. E.U.-wide, women made up less than 10% of top boards in 2009. That trails the 15% figure in the U.S. — where a quota is a nonstarter — and drops to just over 9% once Norway's female board members are factored out.
