Around the world, C40 cities are taking bold climate action, leading the way towards a healthier and more sustainable future. 


We have reached a defining moment for our planet. To achieve the goals of the Paris Agreement and avoid catastrophic climate change we need to act faster and with more urgency than ever before. Fortunately, mayors of the world’s leading cities have emerged as strong and inspiring champions of the kind of ambitious climate action the world needs. Cities know what needs to be done to limit global heating to 1.5° Celsius, and they know that achieving this climate-safe future is only possible if we act now and in collaboration with other levels of government, businesses, civil society and citizens.


96 affiliated cities — 25 % of global GDP — 1 in 12 people worldwide — 10,000 actions to combat climate change

We are working together on an international student project by students from C40 cities from around the world trying to answer the questions:

  • Are the emissions reductions goals of the C40 Compact sufficient to stay within the 1.5°C target of the Paris Agreement?

  • Are the cities in the C40 Compact on track to reach those emission reduction targets?

  • What can the students of the Fridays For Future Movement do to spur their local officials to take the actions necessary in line with the 1.5°C target. 


This project also serves as a starting point for school assignments and research papers.


Classroom Assignment:


The C40 Project features 100 cities throughout the world with the best practices as they achieve their goals of being 100% fossil fuel free.  Within the United States, New York leads the way with nine different categories for the innovative work they are doing.  


In the last six months, five cities in South Florida have declared a climate emergency to address climate change and avert an environmental catastrophe.


Read through some of the ideas from different cities across the world.


Research on the internet to find out what ideas has the City of Miami implemented.

Recommend what best practices the City of Miami should adopt.


Present your ideas to the city officials in a speech with a PowerPoint presentation, or in an argumentative essay.
