International organisation internships do not get much better than this. Seven roles are open right now at some of the most respected names in global development, conservation and diplomacy: the United Nations (UNCTAD, UNODA and UNEP's Multilateral Fund), the World Wildlife Fund, the World Resources Institute, Médecins du Monde and Relief International. They span four countries, Canada, Switzerland, France and the United States, and four very different worlds of work: climate and conservation, trade and investment policy, disarmament and international security, and health and human rights. If you are a student or recent graduate 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 mapping invasive species against native wildlife for WWF, testing AI workflows for a humanitarian data platform in Paris, supporting 120+ countries working to protect 30% of the planet, or sitting inside the UN's disarmament office in New York. Each role puts you next to senior professionals doing work that reaches far beyond the office.
There is a strong fit here for almost every profile. Care about the planet? WWF's invasive-species research, WRI's nature diplomacy, and UNEP's refrigeration and climate-technology mapping are all built for environmentally driven applicants. Drawn to policy and diplomacy? UNCTAD's investment-treaty work and UNODA's disarmament office sit at the heart of the multilateral system. Motivated by social justice and health? Médecins du Monde's sexual and reproductive rights work in Montpellier is hands-on and human. Into data, tech and AI? Relief International wants a master's-level intern to help build an intelligent impact platform. Read each role carefully, because they differ in length, location and pay: one is explicitly paid at 20 to 24 dollars an hour, while the UN and NGO internships do not state a wage, so treat them as experience-first opportunities. The deadlines are the real pressure point, most of these close within days, so if one speaks to you, move today.

Want to see how the UN works on disarmament from the inside? The UN Office for Disarmament Affairs is offering a six-month internship supporting its Front Office on disarmament, arms control and non-proliferation, from research and drafting to running its communications.
7. 🇨🇦 Programme Research Intern (Refrigeration and Air-Conditioning Technology) ❄️ UNEP Multilateral Fund Internship in Montreal, Canada 🔧
📅 Deadline: 19 August 2026
An engineering or applied-science student who cares about the climate? UNEP's Multilateral Fund is offering a research internship in Montreal, mapping refrigeration, air-conditioning and heat-pump technologies, alternative refrigerants and training systems across developing countries under the Montreal Protocol.
Seven internships, five world-class institutions, and a genuine door into the international sector. If you scrolled this far, one of them already fits: the conservation and climate work at WWF, WRI and UNEP for the environmentally driven; the trade, investment and disarmament roles at UNCTAD and UNODA for future diplomats and policy minds; the rights-based health work at Médecins du Monde for those who want impact you can see; and the AI and data role at Relief International for the technically minded. Two things should shape your shortlist: location and pay. These sit in Montrouge, Washington DC, Montpellier, Geneva, New York and Montreal, so factor in where you can realistically be based, and remember that only the WRI role states a wage while the rest are experience-first. On timing, this list is ordered soonest-first for a reason: three roles are open on a rolling basis, three close on 18 August and one on 19 August, so waiting almost never helps when places at organisations like these fill fast. Do one concrete thing today: pick the role that fits you, open its link, check the requirements, and start your application. And if you want opportunities like these to reach you the moment they land, rather than scrolling dozens at once, join our broadcast channel through the link in our bio, where we share every new batch first.
