Welcome back to the Going Zero Sustainability podcast! This week, host Seth Combs is joined by industry veteran Jim Green, whose four-decade career has helped shape the modern food service ecosystem. In this episode, Jim Green shares his journey from falling into food service in the 1980s to becoming a key coordinator for change, leading initiatives like the Agora Sustainability Leadership Team and the Optimize Ecosystem Team.

Together, they dive deep into the challenges and opportunities facing operators, manufacturers, and the crucial "middleman" network that defines today’s food service landscape. Whether it’s tackling sustainability, driving innovation in supply chains, or empowering community action, you’ll hear insights and stories from the front lines — plus practical advice for anyone looking to make a difference in their workplace or their local environment.

Tune in to learn how on-premise food service operators are changing the narrative around sustainability, collaborating across industries, and proving that individual action can create sweeping impact. If you’re passionate about sustainable solutions and curious to hear from those driving real change in food service, this episode is for you!

Welcome to another episode of Going Zero, the podcast where we dive into real-world solutions to today’s toughest sustainability challenges. Our hosts, Christy Cook, Eric Passwalk, and Seth are joined by Amielle Lake, CEO of Carbonet, a company pioneering innovative chemistry to help industries recover, reuse, and waste less water—while dramatically cutting down on fossil fuel-based chemicals.

In this episode, Amielle shares her unique journey from digital marketing to sustainability entrepreneurship, and sheds light on the looming threat of global water scarcity. You’ll hear how Carbonet’s breakthrough technology is helping thousands of manufacturers, municipalities, and oil and gas operations treat wastewater more sustainably and cost-effectively—no environmental premium required.

We’ll dig into why water remains an underappreciated resource, the barriers to widespread adoption of new water tech, and the challenges of shaking up a multi-billion dollar chemical “cartel.” Plus, Amielle highlights Carbonet’s real-world impact stories, talks about safety improvements for workers, and discusses her work advancing women's representation in clean tech and investing through the Women’s Equity Lab.

Whether you’re a sustainability manager, a CEO, or just curious about how chemistry can help secure the future of our most vital resource, this episode will inspire you to rethink what’s possible—and the role every stakeholder can play in driving change.

This week, we're sitting down with Stephen O'Brien, formerly of the NY Dept of Education, to discuss driving healthy choices and sustainable solutions to a massive audience - 1.1 million students.

If you’re looking to drive real change—especially in education—Stephen O’Brien’s approach offers a playbook for creating measurable impact in even the biggest organizations. Here’s what you can learn from his experience leading sustainable food service transformation:

3 steps for successful, sustainable change:

**Step 1: Start with pilots, not mandates.**

Stephen didn’t try to overhaul everything at once—he launched small experiments like “Trayless Tuesdays” and salad bar pilots. Success with these prototypes gave him proof of concept and protected him from big, costly failures.

**Step 2: Build coalitions—especially with your end users.**

Lasting change came because he listened to students, staff, nonprofits, and policymakers, using their feedback to design solutions that actually worked for them. When students asked for better serviceware, he collaborated *with* them, not *for* them.

**Step 3: Use scale as leverage, not just as a challenge.**

Stephen pooled buying power through the Urban School Food Alliance. By aggregating demand, he negotiated better contracts for compostable plates and locally sourced food, making sustainable options affordable even in a giant system.

You may not be running the nation's largest school cafeteria, but you can always start smaller, test, scale, and invite others into the journey. Sustainable change is never solo work—and your allies may be waiting where you least expect them (including your youngest “customers”).
