Everybody is an environmentalist, be it bringing a plant back from the brink, recycling responsibly, or volunteering to clean up a beach. The authors of this book have discovered the environmentalist inside them that they have put to good use, and each one has made their own tremendous impact in their field.

The chapter authors of this book have been appointed advisors to Lord Stern, Boris Johnson, Ken Livingstone, Al Gore, Arnold Schwarzenegger, Leonardo Di Caprio, Ban Ki Moon, Michael Bloomberg, Richard Branson, and Bill Clinton. The authors are or have been mayors, deputy mayors, mayoral advisors, leaders of institutions critical to cities, academics or professionals who have led significant bodies of work related to city progress, or communication experts observing and reporting on leading practice. The chapters present some leading practices that can be emulated and financed in another city. The book will inform national governments who can promote, regulate, scale, and signal to the markets where the capital should flow. Furthermore, it will inform businesses looking to invest in our urban and climate future.

The book identifies components of the city in 30 chapters, each with an expert author and in some case co-author. The sum of those parts make up the complete ecosystem of The Climate City. It does not address music, art, theatre, or wider cultural elements, but it does not ignore their role or importance. It builds the story of how cities are using innovative techniques to advance progress, which makes them the ideal leader in tackling climate change.

Each chapter addresses key ideas and how they can be applied in both the developed and developing world and formal and informal settlements, how practices can be replicated and scaled, and what impact this would have on climate targets. The authors provide the reasons behind why cities are leading and describe “systems thinking” as a means of creating true impact and real progress as our cities continue to grow.

The book highlights the steps that cities are taking today and follows the trends we see today, and shows how this translates into the reality of tomorrow. It identifies the contribution cities will make to combating climate change and their role in shaping policy at every level of government. It offers a fact-based economic, technological, and policy-driven journey that every individual can relate to in modern society.

Society has a role to play in both our professional and personal activities, and this book aims to point out the near urban future that is nearly upon us and highlight the opportunities to engage and develop the ideas for keeping us in work, keeping us moving, keeping us warm, and keeping us safe, and ensuring we progress as a society. It will break down the challenge into “numbers” and “stories”, giving us the input we need to drive the right technologies into our urban centres and promoting a progressive society for a better future.

The need to decouple growth from the environmental dis-benefits it brings in cities is wrapped up in our need to solve other challenges such as poor air quality and the inefficient use of resources. Cities will endeavour to show the world how to reach the future needed to avoid the impacts of climate change we are currently hurtling towards. The book outlines the fundamental journey we need to embark on to maximize the contribution of cities to the climate crisis and provide insight into how these practices can be adopted by national governments to promote the economic, social, green, and just outcomes.

The scale of this problem is increasing. In Figure I.4, we can see the number of people and the number of cities on Earth that will be at risk by 2050 due to extreme heat, extreme heat and poverty, water availability, food security, sea level rise, and sea level rise plus power plant. Our growth needs to be governed by new rules that can mitigate against these risks.

The risks and complexities as we transition into this future city will be outlined. The radical shifts in mindset and urban policy to make this a reality will be discussed. How we solve the climate crisis will inevitably lie in solving these problems at a scale and at a pace that is more aggressive than the national governments the cities reside within. This book offers data to show our future path and our role in achieving the truly progressive and liveable city. In the end, we can all play a more valuable role today if we can get a glimpse of the urban world we want to inhabit tomorrow and what it will take to achieve it.

This is a book about meaningful action at a local level. A city or municipality can do more than a little; it can show a pathway for other cities and their national governments to follow and turn something more than a little into something significant.

The image of Fleet Street in London transformed into a place for people (Figure I.5) is actually a depiction of what is required to cut our carbon emissions and adapt the city to the inevitable consequences of climate change. That is the opportunity we have, to deliver a far more liveable city. However, we have to cut our energy use and we have to switch to renewable energy – fast – to solve the climate crisis; everything else in this book is to help protect us further into the future.

I always loved the expression “When you are hanging on by your fingernails, you don’t go waving your arms about”. This is the delicate balance of the city ecosystem. The time has come for cities to find a way of drawing attention to climate action – while still hanging on!

The clock is ticking. On the Mercator Research Institute on Global Commons and Climate Change⁷ carbon clock, at time of publication, the carbon budget will be depleted in 6 years, 9 months, 2 days, 21 hours, 17 minutes, and 19 seconds, after which limiting climate change to a 1.5°C increase will no longer be possible (Figure I.6).
