What is the C40 network?

In the C40 Cities Climate Leadership Group 97 major cities around the globe with more than 700 million inhabitants have joined together to confront the climate crisis and implement the Paris Agreement on climate protection. Why? Nowadays, the majority of people around the world live in large cities where around 80% of global economic output is produced. They are also responsible for 70% of the world’s greenhouse gasses. The mayors of the C40 cities meet every three years. This year’s summit is being held in Buenos Aires, Argentina, from 19 to 22 October 2022.
