Andreas A. Papandreou is Professor of Environmental Economics at the National and Kapodistrian University of Athens. His research centers on the economics of climate change, sustainable development, and the political economy of the environment, with emphasis on how institutions, finance, and public opinion shape climate and energy transitions. Building on earlier work on externalities, institutions, and social choice, his current research examines the economics of adaptation, the financial risks of stranded assets, and the role of uncertainty and ambiguity in climate policy design. He is engaged in interdisciplinary projects on water, energy, and ecosystem governance, as well as initiatives advancing sustainability metrics and ESG integration in policy and business. Looking ahead, his work seeks to clarify how political and economic systems can be restructured to enhance resilience, equity, and the effectiveness of the low-carbon transition.
