Girls Not Brides joins with feminist, women's rights and gender justice movements to advocate for a world where all girls are free to choose if, when and whom to marry, enjoy equal status with boys and men, and are able to achieve their full potential. This advocacy brief explores and documents how each of the six issues identified as critical to achieving gender equality in the Beijing +25 process – gender-based violence, economic justice and rights, bodily autonomy and sexual and reproductive health and rights, feminist action on climate justice, technology and innovation, and feminist movements and leadership – link with child, early and forced marriage (CEFM). It also urges development actors to invest in comprehensive, multi-sectoral, rights-based approaches that address the structural drivers of CEFM and build positive norms to achieve gender equality.
