This summer, five students will pursue prestigious climate-related internships with support from the Institute for Climate and Sustainable Growth’s internship program. The program, supported by the Polsky Energy Transition Leadership Academy, provides stipends to students who have secured external, unpaid positions in the climate and energy fields. 

This year’s interns have departed Hyde Park classrooms for offices in New York, Beijing, Geneva and California, where they’ll dive into the fields of sustainable development, finance, policy and law. Working with leading public and private organizations, the interns will develop real-world experience and build valuable connections for their future careers in climate and sustainable growth.
