Christiana Figueres is a Costa Rican citizen and an internationally recognized leader on climate change. She was Executive Secretary of the United Nations Framework Convention on Climate Change (UNFCCC) from 2010 to 2016. During her tenure at the UNFCCC, Ms. Figueres brought together national and sub-national governments, corporations and activists, financial institutions and NGOs to jointly deliver the historic Paris Agreement on climate change, in which 195 sovereign nations agreed on a collaborative path forward to limit future global warming to well below 2°C, and strive for 1.5°C, in order to protect the most vulnerable. In this exclusive interview, I spoke with Christiana Figueres about her lifelong commitment to building a sustainable future for our planet.
