Carlos Alvarado Quesada served as the 48th President of the Republic of Costa Rica from May 2018 to May 2022, leading one of the most admired small democracies in the world through four of its most consequential years: an historic climate agenda, the COVID-19 pandemic, the legalization of same-sex marriage, and sustained defense of the multilateral order at a moment when that order faced pressure from multiple directions. He took office at 38 — one of the youngest heads of state in the world at the time — after a career that spanned journalism, political science, government service, and the private sector.
As a sustainability speaker and statesman, Alvarado’s presidency became a reference point in global climate policy. His administration produced Costa Rica’s National Decarbonization Plan, the first in the world to align fully with the goals of the Paris Agreement, and implemented it with practical results: electric vehicles became the most common new vehicles sold in Costa Rica, coffee farming was certified carbon negative, and ocean protection was expanded from 3% to 30% of the country’s exclusive economic zone. In September 2019 he accepted on behalf of Costa Rica the UN Champion of the Earth Award for Policy Leadership, presented by the United Nations Environment Programme, the highest environmental honor the UN bestows. In 2022, the National Geographic Society awarded him its Planetary Leadership Award for outstanding commitment and action toward protecting the ocean.
Alvarado’s government also oversaw one of Latin America’s most effective COVID-19 responses, deploying universal testing, contact tracing, and an early vaccination campaign that positioned Costa Rica among the best-performing countries in the region by key health metrics. His defense of democratic institutions, human rights, and press freedom during his term contributed to Costa Rica’s consistent ranking as the most stable democracy in Central America and one of the most respected in Latin America.
Since leaving office, Alvarado has built a significant post-presidential career as an educator, writer, and advocate. He is Professor of Practice in Diplomacy and Senior Fellow in the Edward R. Murrow Center for a Digital World at The Fletcher School at Tufts University, where he focuses on small states diplomacy and preparing the next generation of global leaders. He is a member and board director of the Club de Madrid, the world’s largest forum of former democratic heads of state and government, and a Richard von Weizsäcker Fellow at the Robert Bosch Academy. In November 2019 he was named one of TIME’s 100 Next — emerging leaders shaping the future and defining the next generation of leadership.
He writes regularly for Project Syndicate on democracy, migration, climate policy, and multilateralism, and has spoken at the Davos World Economic Forum, major universities, and international policy forums across five continents. At a 2025 address at UConn Law School on democracy, human rights, and multilateralism, he told students “there’s a big demand for hope, but a little supply” — and set out to supply it through evidence of what is possible when political will meets institutional strength.
As a speaker, Carlos Alvarado Quesada brings to every stage what is genuinely rare in the current global moment: a former head of state who governed from values rather than fear, led consequential change against the odds, and emerged from office with both his record and his credibility intact.

Costa Rica abolished its military in 1949 and has been at peace ever since. It runs on nearly 100% renewable electricity. It has one of the highest life expectancy figures in the Western Hemisphere. It is consistently ranked the most stable democracy in Central America. And under Alvarado's presidency, it became the first country in the world to produce a National Decarbonization Plan fully aligned with the Paris Agreement. In this keynote, Alvarado examines what the Costa Rica model actually is, how it was built across generations, what his administration specifically added to it, and what lessons it offers to larger, more complex countries and organizations trying to reconcile economic growth, social equity, and environmental sustainability. Not an advertisement for Costa Rica — a case study in what committed, long-horizon governance can produce.
Every political leader who has tried to advance serious climate policy has encountered the same obstacle: the costs are concentrated and immediate, the benefits are diffuse and long-term, and the opposition is always better organized than the support. Alvarado led Costa Rica through the politics of decarbonization from the inside, negotiating with industries, managing public opinion, building international coalitions, and producing measurable results. In this keynote he shares the political and strategic framework he used, the moments where the initiative nearly failed, and what he learned about how to build the public will for transformative change when the science is clear but the politics are not.
The institutions of democracy — independent courts, free press, civilian oversight of security forces, peaceful transitions of power — are easier to destroy than to build and harder to restore than to protect. Alvarado governed a country that has maintained those institutions for three-quarters of a century, and in his post-presidential work at Fletcher and through the Club de Madrid, he has studied what separates democracies that survive pressure from those that don't. In this keynote he examines the specific threats facing democratic institutions today, the patterns of institutional erosion he has observed across Latin America and beyond, and what civic leaders, business leaders, and ordinary citizens can do to strengthen the systems that protect everyone's rights and interests.
Costa Rica sits at the crossroads of Central American migration — a country that has historically been both a destination for migrants and a transit point for those heading north. Alvarado has spent his post-presidential years studying the root causes of migration in the context of climate change, institutional fragility, and economic exclusion, writing for Project Syndicate and advising at Fletcher on what evidence-based policy actually looks like. In this keynote he presents a framework for understanding migration that goes beyond the border crisis framing that dominates political discourse, examining the interplay of poverty, violence, climate displacement, and institutional failure that drives people to leave, and what the international community can and cannot realistically do about it.
