Big cities don't have to mean a dystopian future. They can be turned around to be powerhouses of well-being and environmental sustainability - if we empower women. This book is a unique collaboration between C40 and Friends of the Earth showcasing pioneering city mayors, key voices in the environmental and feminist movements, and academics. The essays collectively demonstrate both the need for women's empowerment for climate action and the powerful change it can bring. A rallying call - for the planet, for women, for everyone. You can't save the planet without equality ? We need a new economics informed by the larger picture, an economy that puts women and the Earth at the centre.
