Strong public institutions and mechanisms to ensure accountability for fulfilling gender equality and mainstreaming commitments. Tools for evidence-based and inclusive policy making that account for potentially different effects on women and men. Effective monitoring mechanisms and reliable gender-disaggregated evidence for making informed policy decisions. For example, Mexico’s National Women’s Institute developed an institutional mechanism called “National System for Equality between Women and Men”, which co-ordinates the gender-related work of 42 federal agencies.
