“To be an effective climate optimist and person who cares about sustainability, you need equal parts of two different ingredients. The first is inspiration, because if you don't believe you can make a difference, and if you don't believe that what you do matters, then you're not going to try. You also need the other ingredient of empowerment. If you are really, really encouraged to try to make a difference, but you're not given the tools or the knowledge, then all that energy dissipates and becomes wasted.” —Charlie Sellars

What if sustainability wasn’t a burden, but an invitation? For too long, we’ve been told to shrink our impact and feel guilty for not doing enough. But what if the real power lies in small, positive choices that actually feel good and make a difference?

Charlie Sellars, the Director of Sustainability at Microsoft and author of What We Can Do: A Climate Optimist's Guide to Sustainable Living, has spent his career turning eco-anxiety into practical, empowering action. His journey proves that you don’t need to be perfect—or even an expert—to make sustainability work for your life, your business, and your happiness.

Tune in as Justine and Charlie break down how to reframe sustainability from a source of stress into a source of strength, sharing real-life stories, actionable tips, and a new way to think about your impact—one that’s positive, empowering, and actually doable.

Meet Charlie:

Charlie Sellars is a Director of Sustainability at Microsoft, which pledged to become Carbon Negative, Water Positive, Zero Waste, and Protect Ecosystems by 2030. As one of the youngest directors at the company, he has overseen sustainability for both the Windows & Devices and Cloud Operations portions of Microsoft, helping launch several sustainability-forward products ranging from new Windows PCs with repairable and recycled components to the Ocean Plastic Mouse.

Recognized by IM100 as one of 2024’s top 100 most impactful individuals in the digital infrastructure industry, Charlie also serves as a governing body member of the iMasons Climate Accord, an industry coalition united to decarbonize the digital infrastructure that underpins the next generation of cloud and AI services.

Charlie has previously served as a board member and CTO of an impact-focused non-profit, The $100 Solution, which believes that “solutions to big problems start with small steps.” He initially joined this non-profit while studying for his Bachelor of Arts degree in Physics from Williams College, a small liberal arts school nestled in the Berkshire mountains which helped to grow his love for nature.

Raised outside Milwaukee, Wisconsin, Charlie is currently based in Minneapolis, Minnesota.

What We Can Do: A Climate Optimist's Guide to Sustainable Living by Charlie Sellars

“An interdisciplinary approach to medicine is probably the way the future is going to go. There will be dieticians and a whole host of different people involved in helping someone to heal.” —Jonathan Carp

For too long, we’ve been told that health comes in a medicine bottle or a doctor’s office, but what if the real power lies in the food we choose every day? If you’ve ever felt frustrated by quick fixes that don’t last or wondered how to make healthy changes that actually stick, you’re not alone—and this episode is for you.

Dr. Jonathan Carp is a board-certified dermatologist and the founder of Miracle Noodle, a company born from his passion for using nutrition and lifestyle to transform health. With years of experience helping patients and building a wellness brand, he’s on a mission to make healthy eating accessible, enjoyable, and truly life-changing.

Tune in as Justine and Dr. Carp break down the myths about comfort food, reveal how small changes can lead to big results, and share real stories of healing, grit, and the surprising joy of eating well.

Meet Jonathan:

A Dermatologist since 2000, Dr. Jonathan Carp started Miracle Noodle in 2006. In 2004, he had a patient who healed herself from lupus through nutritional and lifestyle modification.

Since then, he has treated hundreds of patients through lifestyle modification, especially nutritional changes, with a special interest in auto-immune diseases. This has turned into a nutritional obsession that led to his learning about the health benefits of the konjac plant.

While he still practices medicine, a significant amount of time is now also devoted to Miracle Noodle and exploring and testing healthy, healing food options based on traditional cultural diets. Dr. Carp firmly believes that all that ails us in the world today could be solved by going back a few generations and making sure that the nutritional wisdom of our ancestors is remembered and combined with the latest science.

While Miracle Noodle keeps him busy, it has allowed him the resources to investigate and learn about the nutritional wisdom of the world and how to get products and knowledge out to the world through his patients and his companies.

“In the old days, families worked together, like on a farm, and that's the model we wanted to create for ourselves at EO Products.” —Brad Black

Most businesses die because they chase profits instead of purpose—a raw, honest truth that cuts to the core of entrepreneurial burnout and lost passion. A lot of entrepreneurs pour their hearts and soul into a business, only to become a slave to spreadsheets and profit margins. But what if there was another way?

Brad and Susan Black, co-founders of EO Products, are pioneering entrepreneurs who transformed a passionate curiosity about essential oils into a 30-year sustainable business empire.

With a background in recycled fabrics and ethical manufacturing, he has been crucial in developing the company's operational strategy.

In 1995, Susan and Brad co-founded EO Products, leveraging their complementary skills and shared values to create a pioneering natural personal care brand. Starting with four blends for the Bloomingdale's catalog, they built a company dedicated to using pure essential oils, sustainable packaging, and transparent manufacturing.

“You follow your passion, and when you have a purpose behind it, everything becomes a little bit clearer.” —Nancy Rimbergas

Clean beauty isn't just another Instagram hashtag—it's a real movement that starts with actually caring about what we're putting on our skin. Every lotion, cream, or serum is like a tiny decision that ripples out, affecting not just our body, but the whole planet. We're not just buying products anymore; we're voting with our dollars, pushing brands to be real about their ingredients, and showing the beauty industry that we want something better.

Nancy Rimbergas is the co-founder of Earth Based Body, a purpose-driven skincare line that harnesses the potent, scientifically backed ingredients native to the Sonoran Desert. By prioritizing local, non-toxic ingredients and maintaining a commitment to transparency, she aims to bridge the gap between natural wellness and high-performance beauty.

Meet Nancy:

Nancy Rimbergas is a Chicago native drawn to the mythical desert from an early age when visiting with family. Her connection grew with each visit, and she finally took the leap and moved to Arizona to experience the desert every day. True to her maximalist vibe, she now lives the Earth Based Body lifestyle with her husband, surrounded by an obnoxious amount of original artwork collected through their travels.

“I had to find that niche, that core community of people who were trying to solve the same problems that I was and who were passionate about the solution. But if I hadn’t found that, I think it would be tough to try to keep promoting your product and your brand without actually knowing where it fits.” —Belinda Lau
