Understanding how anti-gender actors impact negotiations, the adoption and implementation of treaties, alliance building, and polarisation within multilateral structures is crucial – not only to counter anti-gender actors but also to preserve and improve our multilateral order, which is vital for human rights across the world, in particular of persons subject to (intersecting) forms of discrimination and marginalisation. The core output of this research project scheduled for publication in October 2022, financially supported by the Finnish Ministry for Foreign Affairs, will be a comprehensive study analysing the impact of anti-gender actors on multilateral structures in Europe and providing concrete recommendations for policymakers, both in governments and international organisations.
