Editor's Note: Climate change, extreme weather events, ecosystem degradation, biodiversity loss… As our planet faces an existential threat, countries and multilateral organizations are working with increasing urgency to find solutions. Despite hurdles and setbacks, there is now a growing consensus about the need for global cooperation and action. In this edition of Leaders Talk, CMG's Zou Yun sat down with Inger Andersen, under-secretary-general of the United Nations and executive director of the United Nations Environment Programme, to discuss the challenges that China and the world face as countries strive together for net zero, for living in harmony with nature and for a pollution-free world. "We shouldn't panic, we should get focused," she says. China is a case in point, being the world's leader in renewable energy and the driving force behind the Kunming-Montreal Global Biodiversity Framework. She commends China's presidency of the COP15, noting that goals and targets are consistent with China's principle of ecological civilization. Andersen however warns against geopolitical wrangling and the disruptive repercussions toward achieving green targets.
