Canada is having a moment: our reputation and soft power are growing. In the face of unexpected tariffs, a deepening housing crisis, and skyrocketing cost of living, Canadians are asking who we really are, what we want to stand for…and what lies ahead. There is great opportunity to be had, but also great risk in the road ahead. Canada needs energy independence and geopolitical protection - but Mark Carney’s federal government seems to be choosing a path of further baking in fossil fuels, rather than forging a progressive path that assures a safe future for all. Cities - and the people who call this country home - are asking for a different way forward.
The science is clear, and it’s telling us we need to make big changes. But we know that science alone is not enough to turn the tide of the climate crisis. We need to figure out how to tell better, more community centered stories around the impacts happening on the frontlines, in our own backyards…and we need elected leadership across the country to listen, learn, and act in the best interests of Canadians.
In the first episode of this special 6-part miniseries, we hear about the science, data, and politics that brought Canada to this crucial moment - and while we unravel the complicated history of how we got here, we also begin to look forward to the solutions we need to protect the people and places in this land we call Canada.

TRAILER: Oh, Canada: Solutions for the Climate Crisis
Season 8 · Episode 1
Tuesday, September 29, 2026 • Duration 01:57
Climate change can feel frightening and uncertain - so much so, in fact, that sometimes hope can feel like an act of denial. But hope isn’t denial: it’s a recognition that we still have choices.
In our new Cities 1.5 limited miniseries, Oh, Canada: Solutions for the Climate Crisis, we’re speaking to Canadians from coast, to coast, to coast, who are turning those choices into action. Featuring voices from politics, academia, activism, and municipal leadership - including Leader of Canada’s NDP Avi Lewis, Otipemisiwak Métis Government's Provincial Secretary of Women, Gender Equity & Inclusion Gabrielle Blatz, former Minister of the Environment Steven Guilbeault, Executive Director of Re.Climate Amber Bennett, Executive Director of the Pacific Institute for Climate Solutions (PICS) Ian Mauro, Assistant Professor of Fire Ecology at University of British Columbia Okanagan in the Center for Wildfire Coexistence Dr. Jen Baron, writer and public policy researcher Seth Klein, and mayors from Yellowknife, Waterloo, Clearwater, Jasper, and more - we’ll be exploring the science, politics, and communities on the frontlines of the climate crisis across Canada.
Oh, Canada: Solutions for the Climate Crisis is supported by Elbows Up for Climate, The C40 Centre, and the University of Toronto Press. This 6-part deep dive into the climate crisis through the lens of Canadians fighting to write a different story debuts on October 6, 2026, so make sure you tune in - you won’t want to miss it.

HOT TAKE: "A Captain never leaves his ship."
Thursday, August 20, 2026 • Duration 20:53
When the full-scale Russian invasion of Ukraine began in February 2022, local leaders found themselves thrust onto the frontlines of both military defense and environmental catastrophe. Coupled with untold amounts of human suffering, the war has inflicted deep environmental scars - from the destruction of the Kakhovka Dam to the corrosion of municipal water pipes - which many Ukrainian officials refer to as "ecocide." Yet, amidst daily bombardment, energy blackouts, and severed water supplies, city leaders and residents are demonstrating what true urban resilience looks like on the ground.
In this special bonus episode, we hear from a mayor who refused to abandon his city when it was encircled in the early days of the war; a man who led the Ukrainian city of Mykolaiv through eight months of near-daily missile attacks. Despite ongoing attacks,the city is using decentralisation, solar-powered infrastructure, microgrids, and real-time data analysis to keep critical municipal services running during wartime. These strategies keeping cities resilient against military aggression also offer vital lessons for surviving climate impacts globally, as well as forming the bedrock of plans to rebuild in a way that benefits people and planet, when the violence finally stops.
HOT TAKE: Urban Legends - Sorting City Climate Facts from Fiction
Thursday, August 6, 2026 • Duration 29:30
As the climate crisis accelerates, our information ecosystem has become a critical battleground. Coordinated climate disinformation - driven by fossil fuel interests - is increasingly targeting cities and urban leaders to stall transformative policy and manufacture public doubt.
In this special Hot Takes episode recorded on the ground at London Climate Action Week, host David Miller examines how cities are actively defending information integrity and reclaiming the narrative. We look at why proactive storytelling and pre-bunking are far more powerful than traditional fact-checking, how mayors serve as vital trusted messengers in noisy digital spaces, and the stark reality of how disinformation threatens life and resilience on the frontlines of Ukraine. We will also be exploring how the C40 Centre itself incubated the recently launched City Climate Facts that aims to support cities in fighting disinformation, and cleaning up our urban information ecosystem.
Featured guests:
Adam Brzezinski, British Academy Postdoctoral Fellow at the London School of Economics and Political Science
Chiara Morfeo, Senior Manager for Research and Communications at the C40 Centre
Oleksandr Senkevich, Mayor of Mykolaiv, Ukraine

As the AI boom drives an unprecedented rush for computing power, cities face a critical question: how do we support digital expansion, without derailing net-zero climate goals? Left unregulated, data centers can consume staggering amounts of energy and water, threaten to destabilise power grids, strain local resources, and alienate communities. But it doesn’t have to be like this: city leaders are stepping up to demand both climate-friendly solutions and accountability for big tech. In this Hot Take, we explore how local leaders are moving to prevent a digital “wild west” through international collaboration. We examine the launch of the Global Urban Data Centers Pact - a landmark commitment from 41 mayors across six continents, representing 90 million people - which aims to enforce clean energy mandates, water stewardship, and tangible community benefits for future data center development.

The winds of change are blowing through the world’s maritime hubs…despite some national governments’ efforts to the contrary. While the shipping industry carries 90% of global trade, it also leaves a heavy carbon trail in its wake. In this episode of Cities 1.5, we explore the high-stakes transformation of our global ports: once seen as industrial hotspots of pollution, these urban harbours are emerging as the front lines of the green transition. We dive into the groundbreaking "Green Shipping Corridors" that are linking sustainable cities, and the bold shift toward zero-emission fuels. From local air quality to global supply chains, discover how cities are turning the tide on emissions and steering the industry toward a 1.5°C future. It’s time to rethink the horizon: clearer skies and smoother sailing ahead.

Eric Garcetti, C40 Ambassador for Global Climate Diplomacy and former Mayor of Los Angeles

Creating ecosystems of climate truth: How can cities defend information integrity?
Season 6 · Episode 9
Tuesday, May 5, 2026 • Duration 32:58
From fossil fuel lobbying to coordinated political disinformation campaigns, vested interests have built a profitable disinformation infrastructure designed to spread confusion, polarize debate, and exhaust the public. The good news is that the world is waking up. For the first time in the history of the COP, a Declaration on Information Integrity was agreed upon, with governments committing to address climate disinformation and promote accurate, evidence-based information globally.
But we need to go further upstream - instead of simply fighting falsehoods, we need to build ecosystems where truth can take root and flourish. In this episode, we look to Brazil and speak to an individual who was integral in bringing information integrity both to COP and the international agenda. She makes the case for cities as one of the most powerful forces in reclaiming the narrative, building the infrastructure of truth from the ground up - one community at a time.
The Cloud vs the Climate? Lessons from Ireland on the data centre debate
Season 6 · Episode 8
Tuesday, April 21, 2026 • Duration 32:01
As our lives become increasingly digital, the infrastructure powering them is sparking a global debate: we need data centres, but at what cost to the climate and our access to energy? These massive facilities are the backbone of everything from streaming to AI, yet they consume staggering amounts of electricity and water, often straining local grids and and in some cases, threatening to derail decarbonisation efforts.
In this episode of Cities 1.5, we explore how Ireland became the "canary in the coalmine" for this issue. With data centres projected to consume nearly 30% of the nation’s electricity by 2030, the Irish experience serves as a critical warning – and a roadmap – for cities worldwide. We examine the tension between economic ambition and climate mandates, questioning how urban leaders can manage the rapid expansion of digital infrastructure without derailing net-zero goals. Join us as we dive into the lessons learned from the frontlines of the data centre boom and what they mean for the future of sustainable cities.
HOT TAKE: One day, millions of journeys: Celebrating World Public Transport Day!
Thursday, April 16, 2026 • Duration 19:50
Ready for a ride? In this episode, we’re celebrating the inaugural World Public Transport Day, created by the International Association of Public Transport (UITP), along with its global partners, and we explore why public transport is the beating heart of our cities. From the "rolling focus groups" on Melbourne’s iconic trams to the colorful jeepneys of the Philippines, we share personal stories of connection from urban centres across the globe.
But it’s not just about the journey: we dive into the hard policy making it happen. Discover how Mexico City’s Metro uses unique icons to bridge literacy gaps, how Salvador is empowering women through "Women behind the Wheel," and how Amman’s new electric fleet is clearing the air. Hop on for a celebration of the journeys that move us all!
