UN internships in policy, climate and diplomacy do not open in clusters like this often. Nine roles are live right now at the WMO, UNECE, UNFCCC, UNODA, the UN Department of Global Communications, the EU Delegation to Japan, the OSCE and RTI International, spanning Geneva, New York, Bonn, Tokyo, Belgrade and Florida. If you are a politics, international relations or environmental student trying to break into the international sector, this is exactly the kind of experience that changes a CV, the sort of first step an internship abroad is meant to be. You could be working on climate finance at the WMO, carbon-market mechanisms at the UNFCCC, disarmament and global security with UNODA, EU-Japan diplomacy at the EU Delegation in Tokyo, or communicating the SDGs for the UN in New York. Each one puts you next to senior professionals shaping the issues that define our time.
Whatever draws you in, there is a fit here. Focused on climate and the environment? The WMO, UNECE, UNFCCC and UN DGC roles cover climate finance, energy policy, carbon markets and climate communications, and there is even a hands-on field-science internship with RTI in Florida. Drawn to diplomacy, security and political affairs? UNODA's two disarmament roles (one fully remote), the EU Delegation traineeship in Tokyo, and the OSCE mission in Belgrade are built for you. A clear note on pay: the EU Delegation traineeship is paid and the RTI internship pays 15 dollars an hour, while the UN internships do not state a stipend, so treat those as experience-first. A couple have specific eligibility, the EU traineeship is for EU nationals and the RTI role for US residents, so read each listing. The deadlines are the pressure point, all falling between 26 and 31 August, so if one speaks to you, apply today.
