These remaining gaps not only undermine the well-being of societies, but represent missed opportunities for achieving economic growth that benefits all. To be successful, governments need effective governance mechanisms, and sound public sector capacities to ensure effective implementation of gender equality initiatives. The 2015 Recommendation promotes a government-wide strategy for gender equality reform, sound mechanisms to ensure accountability and sustainability of gender initiatives, and tools and evidence to inform inclusive policy decisions. It also promotes a “whole-of-society” approach to reducing gender stereotypes, encouraging women to participate in politics and removing implicit and explicit barriers to gender equality. This work builds on the extensive expertise developed by the Public Governance Committee and its policy communities, including the 2014 report Women, Government and Policy-Making in OECD Countries: Fostering Diversity for Inclusive Growth.
