Trash Talk: Fresh Takes on Food Waste

Trash Talk: Fresh Takes on Food Waste

Author: Climate One from The Commonwealth Club March 13, 2026 Duration: 1:03:24
Food loss and waste account for up to 10% of global greenhouse gas emissions and cost $1 trillion annually, according to the United Nations. About a third of all food grown on the planet gets wasted, rather than eaten. In developing countries, waste usually occurs between the field and the store, due to poor infrastructure, lack of refrigeration, and broken supply chains. In rich countries, most waste happens after food reaches the store, where consumers don’t buy imperfect food – or buy too much and toss what they don’t get around to consuming. How much pollution, deforestation and starvation could be reduced if we got this problem under control? And how can new tech, including AI, be brought to bear on the problem?

The conversation about our changing planet is often reduced to headlines and political noise, but Climate One moves beyond that. Hosted by Greg Dalton, Ariana Brocious and Kousha Navidar, this podcast from The Commonwealth Club creates a space for the full, complex dialogue we need. Each episode features candid discussions with scientists, policymakers, activists, and thinkers who are on the front lines. The focus is on drawing connections-between personal action and economic systems, between daunting scientific reports and tangible community solutions. You’ll hear analysis that doesn’t shy away from the severity of our situation while actively exploring pathways for genuine progress, from technology and finance to culture and justice. This isn't about alarmism or easy answers; it's about equipping listeners with a deeper understanding of the intertwined challenges and opportunities. Tuning into this podcast means joining a crucial exploration of how we adapt, mitigate, and fundamentally rethink our relationship with the natural world. The dialogue here is built on the idea that confronting the climate emergency honestly, in all its facets, is the first necessary step toward shaping a livable future.
