Where to buy it


If our planet is going to survive the climate crisis, we need to act rapidly.




Taking cues from progressive cities around the world, including Los Angeles, New York, Toronto, Oslo, Shenzhen, and Sydney, this book is a summons to every city to make small but significant changes that can drastically reduce our carbon footprint. We cannot wait for national governments to agree on how to reduce greenhouse gas emissions and manage the average temperature rise to within 1.5 degrees. In Solved, David Miller argues that cities are taking action on climate change because they can – and because they must. Miller makes a clear-eyed and compelling case that, if replicated at pace and scale, the actions of leading global cities point the way to creating a more sustainable planet.


Solved: How the World’s Great Cities Are Fixing the Climate Crisis demonstrates that the initiatives cities have taken to control the climate crisis can make a real difference in reducing global emissions if implemented worldwide. By chronicling the stories of how cities have taken action to meet and exceed emissions targets laid out in the Paris Agreement, Miller empowers readers to fix the climate crisis. As much a "how to" guide for policymakers as a work for concerned citizens, Solved aims to inspire hope through its clear and factual analysis of what can be done – now, today – to mitigate our harmful emissions and pave the way to a 1.5-degree world.

Editorial Reviews

"Solved is a laudable attempt to show the power of local government and the pivotal role cities can play in protecting the environment. The power of place is rightly emphasized as a key tool in the fight for environmental preservation."

<em>Eurasian Geography and Economics </em>

"An easy read, this book will encourage more cities to create implementable emission reduction plans, and all who are city residents to participate. Highly recommended."


"Across seven brisk chapters, Miller takes the reader on a Contiki tour of cities around the world and the incredible things that they are doing on the ground while their national governments dither and their national leaders pose earnestly with Greta Thunberg (or troll her)."

<em>Literary Review of Canada</em>

"If you are feeling discouraged about how little is being done to combat climate change, David Miller’s new book is a real cheer-me-upper."

"David Miller offers insights on everything from city planning to greening public transportation and dealing with waste products. Though Solved focuses on cities, it can certainly inspire citizens to start their own climate initiatives in smaller communities."
