Alex Häuser discusses his role as a Sustainable Development Goals Intern with the United Nations, where he combines environmental science with policymaking. He highlights the need to bring more scientific research directly into global governance and shares advice on UN jobs.
Alex is a trained environmental scientist from Germany, currently working in the Division for Sustainable Development Goals at the United Nations Secretariat. He is a member of the editorial team for the UN’s sole academic journal, Natural Resources Forum, and assists in organising the upcoming UN Ocean Conference 2025. With a strong interest in food systems, Alex is dedicated to shaping policies that promote the responsible consumption of global resources and advocate for healthy diets for all. Before joining the UN, Alex was a political trainee at the European Commission in Brussels. He holds an MPhil in Anthropocene Studies (Geography) from the University of Cambridge, an MSc in Science Communication from Imperial College, and a BSc in Natural Sciences from UCL.
Why are you interested in policy and working for international organisations?
Through my studies, I have explored the complexities of global environmental issues, which have sparked my interest in the policy and public engagement aspects of science. I firmly believe in the power of robust institutions and the public sector to drive meaningful change. Finding my role has been about navigating the intersections of research, media, and policy over the past few years. For now, I regard international organisations as arguably the most potent platform for change, but there is an ongoing debate in my mind as to where I can apply my skills most effectively and achieve the greatest impact.
Why sustainability?
The real question should be: why not sustainability? Today, every aspect of our lives is being reconsidered and restructured to become more sustainable. The term “sustainability” has become so entrenched in global discourse that it often feels overused and, in some cases, utterly misrepresented. To address this, it is crucial to define sustainability clearly within specific contexts and to adopt diverse approaches. That is why I value the Sustainable Development Goals – they provide a clear and comprehensive framework for discussing sustainability, ensuring our approach remains focused and effective.
Top tips for applying to the UN
Although UN positions are competitive and highly sought after, the sheer number of opportunities available means that your odds of getting something may be better than you think.
Honestly, just go for it! Although UN positions are competitive and highly sought after, the sheer number of opportunities available means that your odds of getting something may be better than you think. Approach the application process by emphasising your transferable skills and your motivation to contribute to global causes. Looking back, I would have sought funding opportunities earlier, given that most UN internships are unpaid. It is crucial to manage your finances while pursuing these roles. Many internships now offer remote options, which can be a valuable experience, but be prepared for the challenges associated with remote work, such as time zone differences and maintaining effective communication.
What have you learned from your internship?
Three lessons stand out from my experience. Firstly, while the UN is steeped in history and grandeur, at the end of the day, it is composed of individuals like you and me who are simply passionate about solving global challenges. My involvement with the UN Ocean Conference highlighted this further as I learned that high-profile events focus on public relations, media, and diplomatic etiquette, whereas the substantial political groundwork often occurs behind the scenes and well in advance.
We need more scientists who venture into global politics, just as we need policymakers who understand science.
Secondly, the UN is far from a singular entity. It operates through a network of dozens of specialised agencies and programmes, each focusing on distinct areas – from health and food security to human rights and development. This structure allows the UN to address a range of issues with targeted expertise.
The third lesson, perhaps the most surprising to me, is the relative scarcity of individuals with a natural sciences background within the UN and similar institutions, such as the European Commission. To me that points toward a broader concern: a systematic lack of science-literate policymakers. We need more scientists who venture into global politics, just as we need policymakers who understand science. This is where I see my role – as the person in the middle.
Where do you see your career taking you next?
I am considering pursuing a PhD to deepen my expertise and then returning to the international political scene with a stronger foundation. I want to offer a unique perspective, and I believe that pursuing a PhD would provide me with enhanced insight and credibility, especially in my area of interest: food systems. My long-term ambition is to find that sweet spot where scientific research and policymaking converge. I don’t want to diminish the importance of either role; rather, I see great value in walking in both worlds. With my interdisciplinary background, I am excited about the prospect of making meaningful contributions to sustainable development and global governance in precisely that way.
