Eps 19: Who’s Paying When the Oil Companies Are Gone?

What if one of the biggest environmental challenges in North America was hidden beneath your feet? In this episode of the Markets & Leaders Podcast, host Lyndsay Malchuk sits down with Catherine Flax, Chief Executive Officer of Zefiro, to explore the growing challenge of orphaned and abandoned oil and gas wells across the United States and Canada. Millions of legacy wells remain scattered across communities, farmland, forests, and even near homes and schools. Many continue to emit methane, a potent greenhouse gas, while posing environmental, financial, and public safety challenges that are only now beginning to receive widespread attention. Together, Lyndsay and Catherine discuss how decades of energy development have created a modern-day infrastructure challenge, the role of government and private industry in addressing it, how methane emissions are being measured and reduced, and why innovative financing models, including carbon markets, are becoming an important part of the solution. This conversation goes beyond the environmental headlines to examine the intersection of energy, infrastructure, sustainability, investment, and long-term economic responsibility.
