Up to a third of all food produced globally is lost or wasted, and up to 10% of greenhouse gas emissions are tied to it. The opportunity to fix that sits largely inside professional kitchens, and most of them have no system for even measuring the problem. That is exactly what Andrew Shakman in Leanpath was built to change.

Andrew's reframe for kitchens is simple and a little uncomfortable: they are factories. High volume, high complexity, constantly changing menus, and almost none of the process improvement thinking that transformed manufacturing over the last century. No Six Sigma. No statistical process control. Just skilled people running on experience and a deep, quiet anxiety about running out of food. That anxiety, Andrew explains, is where most waste actually comes from. Not negligence, not carelessness, but a system designed to use waste as a buffer against risk. Once you see it that way, the problem starts to look solvable.

Leanpath's approach is to make the invisible visible. A camera above a bin, a scale underneath it, and suddenly a kitchen knows not just that food is being wasted, but what, how much, and why. Andrew walks through twenty years of that evolution, from rudimentary touchscreens and USB sticks in 2004 to AI-powered tracking today. He also makes a case that doesn't get made often enough: that frontline kitchen workers are among the most underestimated climate actors in the world. They already understand the value of food. What Leanpath gives them is the data to act on it, and the evidence that their daily choices add up to something impactful.

Andrew Shakman is the CEO of Leanpath, a company on a mission to make food waste prevention everyday practice in professional kitchens worldwide. Before any of that, he was a child actor, a film school graduate, and a digital marketer selling Cap'n Crunch on the early internet.

Andrew Shakman did not set out to work in sustainability. He set out to tell stories that mattered. What drew him, from early childhood through film school and into his career, was a hunger for meaning and a fascination with how things work. His father was a preventive medicine pioneer writing about food and health in the 1970s, long before the medical world caught up. It took Andrew ten years of running Leanpath to realize he had followed the same instinct into a different field. That kind of slow, earned self-awareness runs all through his story.

What makes Andrew's background so interesting is how little of it looks deliberate from the outside. Theater in college. An MFA in film producing. One of the first digital marketing agencies on the early internet, where he happened to land food and beverage clients. Each chapter looks like a detour until Andrew connects the dots himself, and suddenly the whole thing makes sense. By the time he stumbled into food waste, he had already spent years learning how to build things, how to bring people along, and how to make a complex problem feel urgent to someone who has never thought about it before. He calls it baking a four-layer cake: get people to care about food waste, convince them prevention beats composting, show them measurement is the path to prevention, then make the case for automation. Most conversations never made it past the first layer. It turned out those were exactly the skills that problem needed.

Nancy Zavada returns for part two of her Green Champions conversation, this time pulling back the curtain on the actual work behind sustainable events. As president of MeetGreen, Nancy has saved clients $7.8 million in sustainability-driven decisions and cut $2.5 million in aisle carpet alone from a single event last year. This episode is a masterclass in making the business case for doing things better.

On a cross-country flight, she ordered tea in economy and got a styrofoam cup, a plastic stir stick, and a sugar packet. On the way back, upgraded to first class, the same tea arrived in a china cup with a silver spoon and a sugar cube. That airline wasn't trying to be sustainable. They were trying to be elegant. Nancy's point is that we've somehow convinced ourselves that sustainability means sacrifice, when the most refined, considered experiences have always been the most efficient.

The practical strategies Nancy shares in this episode are the kind that stick. The Clean Plate Club, which turns food waste reduction into a community game at multi-day conferences. The stone-in-a-jar voting system that replaced conference swag with charitable giving. The carbon uncalculator MeetGreen built during COVID to show clients exactly how much emissions they avoided by going virtual. And the emerging Hub and Spoke event model that she believes is the next major shift in how organizations gather. Each idea is grounded in the same philosophy: reduce first, always. Then measure, share the data, and let the numbers do the talking.

Nancy Zavada is the founder and president of MeetGreen, a sustainable event agency that has spent over 30 years helping organizations design and deliver events that are both environmentally responsible and genuinely exceptional.

Nancy grew up on the Oregon Coast, where recycling wasn't a trend but a way of life. She never set out to start a company. She was simply an event planner who noticed something she couldn't unsee: a single five-day conference for 2,500 people would generate 31,000 styrofoam cups destined straight for the landfill. That moment didn't just bother her. It moved her. She made one different ordering decision, told everyone about it, and never looked back. That's the kind of founder Nancy is. Not the type chasing product market fit, but the type whose values simply outgrew the room she was in.

What followed was 32 years of building MeetGreen into a firm that serves clients from 300-person workshops to 60,000-person global conferences across Singapore, Brazil, Denmark, and beyond. Nancy shares the practical wisdom behind her approach: find the champion in every room, lead with education, and always make the business case. She also offers a beautifully simple piece of advice for young sustainability professionals: don't try to take on the world. Pick one thing. Get really good at it. Then pick the next one.

Karimah Hudda, founder of Illumine Earth, returns for part two of her conversation with Dominique and Christy. After exploring her roots, Karimah dives into her "champion story." From the mountains of Indonesia to the boardrooms of global giants, she shares the tactical moves and mindset shifts required to rebalance power in global supply chains and lead with purpose. Karimah recounts a powerful story from Aceh, Indonesia, where a simple shift in strategic planning allowed 100 farmers to fundamentally change their relationship with exporters. It’s a vivid reminder that real impact isn’t about doing the work for people, it’s about providing the tools for them to unleash their own potential. Karimah challenges the idea that systems change has to be slow and complicated, offering a refreshing mantra for anyone trying to make a difference: simplify, believe in people, and stay messy.

The conversation also tackles the corporate "survival guide" for sustainability leaders. Karimah breaks down her signature framework for driving change without burning out. She explains why you must learn the "language of the business" (because the business won't learn yours) and how to balance personal, enterprise, and industry leadership.

Karimah Hudda, founder of Illumine Earth, has spent two decades working where sustainability, leadership, and global systems meet. She discuss how her multicultural upbringing and work across 50 countries shaped her approach to equity. Karimah shares how she navigates the complexities of power to turn core values into real-world action.

Why do we introduce ourselves by our titles instead of our roots? For Karimah Hudda, the journey didn’t start in a boardroom. It started with her grandmother’s courage in a small Indian village. Karimah shares how a legacy of compassion and a belief in "shared humanity" led her from studying microbiology to transforming global supply chains. She takes us behind the scenes of the Fairtrade movement, explaining how simple shifts in equity can change the lives of hundreds of thousands of farmers.

But how do you bring that grassroots mission into a massive corporation? Karimah pulls back the curtain on her time at giants like Mondelēz and Nike, revealing the "messy" reality of corporate sustainability. From flying to Zurich weekly to land a global coffee strategy, to using satellites to track the world’s palm oil, she shares what it actually takes to move the needle within a corporate hierarchy.

Season 5 is here, and we have some exciting news. Christy Cook is officially joining Green Champions as co-host! You may already know Christy from her previous guest appearance, and now she's here to stay. If you're missing the voice of former co-host Adam Morris, don't worry. You can still catch him on his podcast, People Helping People, on all listening platforms.

So who is Christy? She's a sustainability consultant and entrepreneur with over twenty years of experience in corporate sustainability, ESG, and customer success, having worked with major players like Walmart, Sodexo, and the UN Environment Program. She's also been a mentor and trusted sounding board for Dominique behind the scenes for years, so this partnership has been a long time coming.

In this intro episode, Dominique and Christy share a little about what makes them tick. Christy's light bulb moment traces back to her time at Emory University, where she got to explore how food systems could create a real sense of place and community on campus and realized sustainability could actually be a career. Dominique's "why" is a little closer to her heart: her family. With relatives living on an island directly impacted by climate change, protecting the planet feels like a personal responsibility, not just a professional one.

Together, they bring different lenses to the work. Christy with her big-picture corporate perspective, Dominique with her engineer's instinct for building processes that are replicable and scalable. As they look forward to Season 5, they promise to explore uncharted territory. From the sustainability of our sports stadiums to the hidden figures in our food systems, all while maintaining the heartwarming, real-world storytelling that has defined the first 100 episodes of Green Champions.

Brody Olson, the Sales Development Manager at Two Men and a Junk Truck, is here to prove that "junk removal" is about much more than just a trip to the dump. It's about empathy, community, and finding a second, third, or even fourth life for the items we no longer need. Brody pulls back the curtain on the often-misunderstood world of junk removal. He challenges the very notion of "junk," reframing it as "unwanted items" and revealing the treasure trove of opportunities for reuse, donation, and recycling. Brody shares the origin story of Two Men and a Truck, a humble summer gig that grew into a nationwide franchise, and explains how the demand for junk removal became a natural and necessary extension of their moving services.

He offers a window into the deeply human side of the business, discussing how his teams navigate some of life's most stressful moments: death, divorce, and moving, with empathy and grace. Brody details their robust diversion process, a multi-stream system that sends furniture to the Furniture Bank of Central Ohio, clothing to Goodwill, and electronics to partners like Columbus Micro. He shares the impressive impact of these efforts, having diverted approximately 40 tons of donatable items in just the last eight months of 2025.

Brody also recounts the overwhelming success of their World Cleanup Day event, where a simple 15-second news segment brought a flood of cars, trucks, and trailers lined up to drop off items for free, proving the immense community desire for accessible and responsible disposal options. The conversation also touches on the emotional side of letting go of possessions, from the challenges of hoarder situations to the dwindling sentimentality of modern furniture.
