Overview of the IISD Geneva Internship Program

The IISD Geneva Internship Program offers students studying in Switzerland the exciting opportunity to acquire direct practical experience with IISD’s office in Geneva.

IISD’s Geneva office has teams focused on the following principal areas:

• Economic Law and Policy (ELP):
  Our team of international lawyers, financial analysts, financial modellers, researchers, communications specialists, and policy analysts focuses on areas of international economic policy-making essential to sustainable development. These areas include investment, trade, taxation, infrastructure, public procurement, finance, agriculture, mining, and sustainability standards. Our work covers international processes ranging from negotiations at the World Trade Organization to those at the United Nations Commission on International Trade Law, as well as regional and multi-country frameworks like the African Continental Free Trade Area and the Energy Charter Treaty. Our team also provides capacity-building support, technical assistance, and other advisory services to governments. We are the host for the secretariat of the Intergovernmental Forum on Mining, Minerals, Metals and Sustainable Development and manage the Secretariat International Support Office for the China Council for International Cooperation on Environment and Development.

• Energy:
  Our team of economists, engineers, policy analysts, communications specialists, and advocates provide practical guidance in two key areas. Our Global Subsidies Initiative (GSI) works to help shift public and private financial flows away from fossil fuels and into clean energy. Our sustainable energy supply and just transition teams work to help countries reduce and phase out fossil fuels in socially responsible ways that are consistent with a 1.5° limit in average global temperature increase. We do this through international processes—including the United Nations Framework Convention on Climate Change, the Sustainable Development Goals and the G20—as well as long-standing programs of in-depth national work in Canada, India and Indonesia and South Africa.

• Resilience:
  Our team of climate experts works with governments, civil society and communities to help them manage climate-related risks, address vulnerabilities, build adaptive capacity, and craft, implement, monitor, evaluate, and learn from their National Adaptation Plans (NAPs). They also conduct research on the nexus between nature and security, along with related work on issues at the nexus of environment, conflict, and peacebuilding. IISD is home to the newly launched Nature for Climate Adaptation Initiative, focused on gender-responsive and socially inclusive nature-based climate solutions, and also serves as the secretariat for the National Adaptation Plan Global Network, which aims to enhance national adaptation planning and action in developing countries through the development of knowledge products, the facilitation of peer learning and exchange, the provision of technical assistance, and the coordination between donors and country representatives to help ensure that bilateral programs align with a given country’s NAP priorities.

  IISD’s State of Sustainability Initiatives program has been advancing sustainable and inclusive value chains since 2008. We provide credible research, strategic advice, and dialogue on voluntary sustainability standards and other related initiatives to help decision-makers promote sustainable production, consumption, and trade.

Experiences of the Previous Interns:

“My experience in IISD has provided me with several and diverse abilities which have been extremely useful, not only to my Masters studies but also to my professional development. Working with a highly dedicated and motivated team, my tasks led me to participate in a variety of projects - all equally interesting and dynamic. My work in the Energy team, more specifically in the Global Subsidies Initiative, provided me valuable expertise in understanding how fossil fuel subsidies negatively interfere in the economy, environment and society, and the importance of reform in order to achieve climate goals. Supervised by an attentive and resourceful mentor, I was able to greatly develop my research and writing skills, organizational and communications abilities as well as creative thinking. My role in IISD has added to my professionalism in a valuable way and has made me a diverse skilled professional". - Masters student from the Geneva-Tsinghua Initiative, University of Geneva, Switzerland
