United Nations spaces are increasingly addressing gender inequality in human rights and international development to promote equity. Accordingly, the anti-gender movement is advancing in UN spaces where their issues are an unexpected feature of debate. They are blocking progress on issues like hunger, infectious disease, and crimes against humanity, and more prosaic areas like UN operations and administration, seeking to water down language on gender and insert provisions exempting them from accountability based on national sovereignty or cultural context. The result of this campaigning harms historically marginalized populations whose rights and personal wellbeing stand to benefit from the norms and protections set in the halls of the UN. To better understand this trend, Ipas mapped 13 cases of anti-gender campaigning in unexpected UN spaces from 2019 to 2023. This executive summary provides an overview of findings from a forthcoming 2024 report, Mission Creep: Expanding Attacks on Gender Threaten the United Nations. It provides key findings and recommendations as to how feminist activists, government representatives, and UN officials can prepare an intersectional human rights response that is cross-cutting, bold, and prepared to defend the universality of human rights.
