The Transatlantic Seminar on Environmental and Energy Economics is jointly organized by four leading institutions—two in Europe and two in the United States—underscoring our commitment to genuine international collaboration. The seminar brings together scholars from both sides of the Atlantic to exchange cutting-edge research and address the most pressing environmental, climate, and energy challenges of our time. Our mission is to highlight state-of-the-art scholarship that employs diverse methods and perspectives, foster intellectual synergies and long-term research partnerships across borders. Ultimately, we hope to cultivate a vibrant academic community that advances scientific understanding, informs policy, and inspires the next generation of researchers to shape a more sustainable future.
