What if planting trees could be not just good for the planet, but also a profitable business?
In this episode, I'm talking with Ben Dell, the founder and CEO of Chestnut Carbon — a company that's raised nearly $400 million, including $250 million of that in 2025, to turn farmland back into thriving native forests across the United States. And he's already forging major carbon removal deals with the likes of Microsoft a...

What if one solution to fashion's waste problem is literally growing on our own heads?

Every day, salons around the world toss out millions of pounds of freshly cut human hair — a clean, protein-rich, renewable resource that mostly ends up in landfills or incinerators. But what if that so-called waste could become the next sustainable textile?

My guest on this episode, Zsofia Kollar, is the fo...

When you hear the word nuclear, does your mind flash to mushroom clouds, Chernobyl, or maybe the glowing three-eyed fish from The Simpsons? Well, what if nuclear electricity — far from being an environmental villain — is actually one of the safest, cleanest, and most land-efficient energy sources we have?

It turns out that former fashion model Isabelle Boemeke is on a mission to change how we think about n...

If you've ever changed a diaper, you might've wondered what happens to it after it goes in the trash. The answer, unfortunately, is that it'll sit in a landfill for hundreds of years—certainly longer than the baby who briefly wore it will live. In fact, every diaper you wore when you were a baby is still sitting around, at best in a landfill, or perhaps even in the ocean. And did you know the average American baby goes...

Recently Alex Shandrovsky had me as a guest on his show, the Investment Climate Podcast to talk about The Better Meat Co.'s recent funding round. When it came out, more than one Business for Good listener heard it and told me they thought it would make a good episode to release to our audience too, so this episode is simply the conversation Alex and I had for his podcast.

If you've been following the alte...

When you think about climate change solutions, your mind might go to renewable energy, electric vehicles, or eating less meat. These are all of course important. But even if we stopped all emissions today, we'd still have too much CO2 in the atmosphere and would need to pull a lot of our emissions out of it.

That's the bold mission of Aircapture, a California-based company pioneering modular direct air cap...

What if the biggest environmental culprits were hiding in plain sight—right on our dinner plates? While most environmental organizations train their sights on the energy sector, Mighty Earth has taken a bold, and often lonely, stand in confronting the meat industry's massive role in climate change, deforestation, and biodiversity loss. In this episode, I sit down with Glenn Hurowitz, founder and CEO of Mighty Earth, to...

It's rare that we contemplate where all the plastic we throw out goes, but rest assured that nearly none of it is being recycled. Simply put, it's usually cheaper to make new plastic than to recycle old plastic, even the plastic you put in the recycling bin. Because it takes plastic centuries to break down, this means for each one of us you could build a mountain of plastic from all the packaging we use over the course...

Plastic pollution is one of the defining environmental challenges of our time—microplastics are now found in our oceans, our soil, our drinking water, and even in our bloodstreams. But what if we could make high-performance materials that look, feel, and function like plastic—without being plastic at all?

Enter Xampla.

Born out of the University of Cambridge, Xampla is a materials science inno...

What if we could grow nutritious, sustainable protein—not in months or weeks—but in just one day?

This episode's guest is doing just that. Rather than going big with animal agriculture, MicroHarvest is going small with microbial agriculture. 

A huge number of animals are used to feed both our pets and the animals we raise for food. Kate Bekers, the CEO and co-founder of MicroHarvest, is seekin...

In this episode, I'm joined by one of America's most thoughtful national journalists: Mike Grunwald. You may know him from his work at Time, Politico, or The Washington Post, or from his critically acclaimed books about the Obama administration and the history of the Everglades. He's also now a contributing columnist at the New York Times. But for the purpose of this episode, Mike is here to discuss his third book, We ...

What if we could turn the mountains of food waste we generate every day into high-value chemicals that replace fossil fuels and palm oil—two of the most environmentally destructive inputs in our economy? That's exactly what this episode's guest is doing.

Marc den Hartog is the CEO of ChainCraft, a Dutch biotechnology company using fermentation to convert agricultural waste into medium-chain fatty acids—ess...

This episode's guest is someone who's spent her career studying—and championing—entrepreneurs who don't always fit the Silicon Valley mold.

Dr. Lori Rosenkopf is the Vice Dean of Entrepreneurship at the Wharton School and the author of the new book Unstoppable Entrepreneurs: 7 Paths for Unleashing Successful Startups and Creating Value through Innovation. In this short guide, Lori explores how success doe...
