Work alongside global thinkers and changemakers committed to a better way forward
At the heart of CCSI is a team working to build a more just and sustainable future

Are you passionate about driving change through research, law, and policy? Curious about how global investment systems can evolve to better serve people and the planet? We work at the intersection of ideas and impact—welcoming individuals from a wide range of backgrounds to help us rethink outdated systems and push for lasting solutions.
Our team is currently full and we aren’t actively hiring right now. We truly appreciate your interest in our work, and we invite you to check this page for updates down the road.
Interns at CCSI contribute meaningfully to research and administrative work while gaining valuable opportunities for learning and professional growth.
We offer a limited number of unpaid and paid research and administrative internships for undergraduate and graduate students (including graduate students in law, business, international affairs, and environmental studies) during the fall, spring and summer. Interested applicants should submit a cover letter, CV, and writing sample ALL TOGETHER IN A SINGLE PDF FILE, in that order. The cover letter should include a distinct list of which internships you are applying for (you may include as many as you’d like). Please submit materials to Nancy Siporin via this application link, unless otherwise specified.
Application deadlines are as follows unless otherwise noted in the descriptions below (although applications will be considered on a rolling basis):
Candidates must currently be enrolled in a degree program, have astute research, analytical and writing skills, and enjoy working on a team. Students enrolled at other academic institutions may apply for all positions, but only students currently enrolled at Columbia University are eligible to receive payment if selected for a paid position. Candidates must commit to at least 10-15 hours per week for Spring or Fall internships unless otherwise indicated, but more hours are possible. Summer internships are full-time (35-40 hours per week) unless otherwise noted. Continuation into subsequent semesters is possible, and course or academic internship credit can be granted in limited cases.
If you are applying for a paid internship, please indicate if you are work-study eligible (preferred but not required).
Paid Internship: Social Value Strategy in the Mining Sector
CCSI seeks a highly motivated graduate student to support a project focusing on long-term social value strategy in the mining sector. The intern will support important research on shared-use infrastructure, local skills development, circularity, nature-based solutions, and approaches to measuring social value beyond compliance norms.
This role will support comparative analysis of general practices in the mining sector and prepare memos and presentation materials for the final strategy deliverables. A minimum of 15-20 hours of work is expected per week, and preference will be given to candidates with strong writing and research skills, attention to detail, and the ability to work on tighter deadlines. Application deadline for this internship is October 6, 2026.
Visiting Scholars can include faculty and researchers from other academic institutions or professionals from industry, museums, or other entities who want to pursue their own independent research using University resources or facilities. Visiting Scholars must apply through Columbia Climate School’s Visiting Scholars Program. Applications for Visiting Scholars are reviewed twice during the year, corresponding with two program intakes, as follows:
