We empower climate leaders to shape the future of the planet.

We are women, we are mayors, we are entrepreneurs, we are innovators, we are students, we are scientists, we are activists. We are dreamers and doers. We are the makers of tomorrow. 

We care deeply about our planet and its citizens, and we are committed to taking action today that will leave a better world for generations to come. 

When we join our voices together, we are unstoppable. We are powerful. We are Women4Climate. 

Women make up more than half the world’s population, and although they are often disproportionately impacted by climate change, their voices are not always heard due to lack of inclusion and representation at the decision-making level. 

Women leaders played a pivotal role in negotiating the Paris Agreement on climate change in 2015, and will be crucial to its success in the future. Now more than ever, enhancing women’s participation and leadership will be critical to securing a healthy, prosperous and sustainable future for us all. 

Through the Women4Climate initiative, C40 aims to: empower and inspire the next generation of climate leaders through a global mentorship program dedicated to women in C40 cities; influence the conversation through leadership events and create new momentum and interest among future leaders; and raise awareness through research on gender, cities and climate to highlight the key role women play in championing climate action in cities.
