Carlos Alvarado Quesada, the former president of Costa Rica, is widely admired as a world leader in the global effort to tackle climate change.
Quesada, who is Professor of the Practice of Diplomacy at Tufts’ Fletcher School, concluded his term as president of the Central American country this past May after four years in office. During that time, Costa Rica won the Earthshot Prize—the only country to be awarded the global prize meant to recognize companies and individuals who’ve devised innovative climate solutions.
