Knowledge is Power
For hundreds of years, people have been pondering the power of information. In this past season of Cities 1.5, we’ve seen examples of cities from around the world who are using data and the lived experiences of their inhabitants to create policies that support healthier lives for people and planet: from Freetown, Sierra Leone, to Tokyo, Japan, to Princeton, Canada. But while history - and our own conversations on this podcast - prove that knowledge is powerful…it isn’t always easy to come by. For the final episode of Cities 1.5 season 5, David meets two knowledge and dissemination specialists who speak with him about the importance of data and information for climate action and what other ingredients are key to effective communications about global heating.

Brick by Brick: Cities and the future of clean construction
The building and construction sector is responsible for a mind-boggling 37% of global greenhouse gas emissions. The kinds of construction materials we use - and the building sector generally - are also responsible for almost a third of global resource consumption. Shifting to cleaner methods of construction is the only way to minimize the damage we are causing to the planet, while still providing homes, workplaces and vital infrastructure for all.Featured guests:Henrique Goes, Clean Construction Manager at C40Vivek Parekh, Fossil Fuels Program Manager at InfluenceMapLinks:The building and construction sector’s share in global greenhouse gas emissions - World Economic ForumUN prediction for rural to urban migration - Our World in DataPremature deaths from household air pollution - World Health OrganizationClean Construction Programme - C40 CitiesReport on clean construction and green job opportunities - C40 CitiesInfluence Map’s LobbyMapInternational Gas Union’s Climate Strategy - Influence MapElectrification as the clearest pathway for decarbonising buildings - IPCC reportState of Victoria’s Gas Substitution Roadmap - Victoria State GovernmentEU’s Energy Performance of Buildings Directive - European CommissionOverturned gas ban in the City of Berkley - The GuardianAdvanced Energy UnitedIf you want to learn more about the Journal of City Climate Policy and Economy, please visit our website: https://jccpe.utpjournals.press/ Cities 1.5 is produced by the University of Toronto Press and Cities 1.5 is supported by C40 Cities and the C40 Centre for City Climate Policy and Economy.

Why we need to adopt a Care Economy
Capitalism is an illness: it’s killing our planet, and by extension, us. Economic instability and environmental concerns are symptoms that can only be cured by redefining prosperity in terms of health and wellbeing, so that we can create sustainable, equitable societies. In his new book, The Care Economy, returning guest Tim Jackson dives into historical and systemic reasons behind our current economic challenges and shares personal experiences that highlight the importance of systemic change in healthcare and beyond. He shares insights from his book around the philosophical and practical implications of fostering a balanced, care-oriented economic model - and how it might just save the world.Image credit: Fernando Manoso-Borgas Featured guests:Tim Jackson, ecological economist, radio dramatist, Director of the Centre for the Understanding of Sustainable Prosperity (CUSP), and author.Links: Prosperity without Growth - Tim JacksonPhysiologist Walter Cannon - National Library of MedicineAneurin Bevin, architect of the NHS - BBCCurrent epidemic of chronic disease - CDCEcological Economics - The International Society for Ecological EconomicsThe Flexner Report - National Library of MedicineCities as Urban Laboratories - Cities 1.5If you want to learn more about the Journal of City Climate Policy and Economy, please visit our website: https://jccpe.utpjournals.press/ Cities 1.5 is produced by the University of Toronto Press and Cities 1.5 is supported by C40 Cities and the C40 Centre for City Climate Policy and Economy.

Out of the frying planet and into the fire: Stories from the frontlines of climate-driven migration
As global temperatures and sea-levels rise, so to does the frequency of climate-driven migration. The search for a safe, healthy, and prosperous place to live has been a feature of humanity since time immemorial...but an increasingly polarized and toxic global discourse sees migrants being increasingly demonized, which makes it hard to have much-needed conversations around the issue. For many migrants of the climate crisis, cities are the end destination, which means that our urban centres need to be prepared for these new realities by adapting infrastructure, services, and policies to create healthy and resilient environments for all residents - old, and new. It’s way past time to open up the conversation.Image credit: Jody FosterFeatured guests:Spencer Coyne, Mayor of Princeton, BC, Canada.Jazmin Burgess, Director, Inclusive Climate Action; Giovanni Pagani, Senior Manager, Climate and Migration; and Claudia Huerta, Senior Manager for City Diplomacy and Campaigns, Climate and Migration.Links: Simon Kofe’s speech to COP26 - New Scientist (Video)Why cities must prepare for climate migration - C40 Knowledge HubThe far right is weaponizing climate change to argue against immigration - VoxFlooded Princeton, B.C., faces days without heat, says mayor - CBC News (Video)$1.7 billion flood projects still stalled in Abbotsford, Princeton and Merritt - Vancouver SunFuture urban landscapes: Climate migration projections in cities - C40 Knowledge HubC40-MMC Global Mayors Task Force on Climate and Migration - C40The ‘Climate Migration’ Narrative Is Inaccurate, Harmful, and Pervasive.

The Fate of the Inflation Reduction Act in the Second Era of Trump
The United States of America’s second withdrawal from the Paris Climate Accord under the Trump administration has enormous implications for both international and local climate efforts - and the Inflation Reduction Act is also potentially under threat. If the IRA is even partially repealed, it would be a huge step backwards in the fight against the climate crisis. But all is not lost - engaged individuals and organizations are striving to ensure the it stays and place, and more broadly, cities, mayors, and subnational entities are playing a critical role in continuing climate action amidst federal challenges. This coalition of actors are leading the growing resistance movement stateside and globally, proving the importance of local level engagement in the bid to halt climate breakdown.Image credit: Chelsea Matson PhotographyFeatured guests: Kate Johnson, C40 Regional Director for North AmericaAmy Turner, Director of the City's Climate Law Initiative at the Sabin Center, Columbia UniversityLinks:Trump signs order to withdraw US from Paris climate agreement for second time - The GuardianElon Musk Says DOGE Aims to Finish $1 Trillion in Cuts by End of May - BloombergThe Data Hoarders Resisting Trump’s Purge - The New YorkerInflation Reduction Act Archives C40 websiteClimate action and the Inflation Reduction Act: A guide for local government leaders - C40 Knowledge HubOne Year After Trump Decision to Withdraw from Paris Agreement, U.S. Cities Carry Climate Action Forward - C40 websiteAppeals Court Keeps Order Barring Federal Funding Freezes in Place - New York TimesIf you want to learn more about the Journal of City Climate Policy and Economy, please visit our website: https://jccpe.utpjournals.press/ Cities 1.5 is produced by the University of Toronto Press and Cities 1.5 is supported by C40 Cities and the C40 Centre for City Climate Policy and Economy.

Risky business: How disinformation fanned the flames of the LA wildfires...and why insurance could help mitigate future climate impacts
Risk is an integral part of the human experience…but risk also needs to be managed if we are to live safe, healthy and happy lives. The recent wildfires in Los Angeles were a tragic reminder of the risks that the climate crisis poses to health, homes, habitats, and the lives of human beings. But the risks posed by extreme weather events are also multi-faceted: disinformation in the wake of hurricanes and wildfires can lead to chaos, with online hate transforming into real-life violence. The insurance industry is based on mitigating risk - but for cities with high probabilities of climate impacts such as wildfires, the risk is becoming too great and financially unviable. There is hope, though: insurance can be used as a climate adaptation tool, reducing risk, to better protect people, cities and the planet.

Dark Machines: AI, Climate Action, and the Future of Our Cities
We live in the age of technology…in the blink of an eye, the Internet and social media have created new opportunities, jobs, and possibilities for connection. But they have also fuelled polarization, persecution, and real-world violence. Artificial intelligence, or AI, promises to turbocharge this revolution. But many questions remain unanswered by the advocates of these new technologies. Can we afford to let AI use infinite amounts of energy? Is it possible to create planetary responsible AI, or is that just a pipe dream? And if the need arises, how can we resist these dark machines?Image credit: This image was AI-generated and does not depict real events.Featured guest:Victor Galaz is an academic and author whose expertise lies at the intersection of governance, climate and technology.
