The United Nations Population Fund (UNFPA)– United Nations Children’s Fund (UNICEF) Global Programme to End Child Marriage works with many partners to advocate and support practical actions to end child marriage and to promote gender equality and the empowerment of adolescent girls. This note illustrates how policies, services and programmes can be designed and delivered to ensure that no one is left behind by integrating human rights-based and intersectional approaches. It builds on other technical notes from the Global Programme, including the notes on gender transformative approaches and on value for money. This note is evidence-based and informed by the promising practices of UNFPA, UNICEF, partners and other agencies.
