Rémy Rioux is chief executive officer of the French Development Agency, or AFD. But before that, in 2015, he worked as chief negotiator on the finance track of the landmark Paris Agreement on climate. Since then the United Nations Conference of the Parties has grown into a behemoth, with COP 27 in Egypt attracting 40,000 people.

Devex sat down with Rioux on the sidelines of COP 27 to hear his thoughts on how the summit has changed since 2015 — and if it’s become an opportunity for greenwashing.

In this wide-ranging interview, Rioux also discussed the prospects of the AFD providing loss and damage financing and supporting nuclear energy programs through its aid program, and whether human rights in Egypt were helped or hindered by the summit.
