C2G: How can the idea of a planetary emergency help the world emerge from crisis?

"Understanding that we face a planetary emergency can help countries and citizens around the world overcome our many interlocking crises, says Sandrine Dixson-Decleve, co-president of the Club of Rome during aC2GTalk interview. Bringing international, national and local leaders into inclusive, people-focused governance processes can help our emergence into a new type of civilization. "
