Cities 1.5

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 Mar...

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 vo...

What if there are reasons to hope for a more resilient climate future in your own backyard - right here in Canada? Well, that’s exactly the question we’re asking in our new miniseries, Oh, Canada: Solutions for the Climate Crisis.  At Cities 1.5, we’re proud to join forces with voices around the world for the 2026 #BeHope Podcast Takeover. We’re coming together to prove that even in challenging ti...

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...

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 c...

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...

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 em...

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 ad...

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 dec...

 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 person...

Cities aren’t just structures. They’re people. In the rapidly urbanising cities of the global majority, many of those people are migrant workers.  They often work informally, with limited protection when shocks hit. At the same time, they are vital to propping up and rebuilding cities after climate disasters. In this week’s Cities 1.5 podcast episode, host David Miller speaks to Ritwika Basu, an e...

In this episode of Cities 1.5, we bring you another "Tale of Two Cities" - but this time, David sits down with two pioneering mayors from opposite ends of the globe.

In a world where climate emergencies are being declared daily, why do so many of our city streets and public transport networks have misleading ads for the very industries driving the crisis? Our conversation with two C40 experts reveals how the fossil fuel industry mirrors old tobacco industry tactics using sophisticated techniques to "greenwash" their image and frame essential health p...

Early scientific warnings about global heating have long stood in tension with corporate narratives shaping public understanding. This episode examines the enduring disinformation created and disseminated by the fossil fuel industry: how it evolves, why it persists, and what it...

Across the United States, cities are acting as climate first responders - carrying climate action forward even as national politics grow more hostile. From clean energy and buildings to transport, land use and resilience to extreme weather events, mayors are proving that climate leadership does not depend on federal permission. It grows from proximity: to people, to impacts, and to the places lead...

In times of profound geopolitical turbulence - wars, trade shocks, energy insecurity, and climate breakdown - something unexpected is happening: while autocratic leaders double down on fossil fuels and climate denial, cities are stepping into the breach to create a different story. One of hope, resilience, and innovation. Like wildflowers pushing through concrete, cities around the world are exper...
