Luke Purdy, Wieden+Kennedy's Director of Sustainability, on Advertising's Power To Change
Can the industry that taught the world to consume help us learn to consume more responsibly? Luke Purdy, Director of Sustainability at one of the world's leading creative agencies Wieden+Kennedy, is betting his career on it. After 13 years working on major accounts like Nike and Corona at one of the world's most influential creative agencies, Purdy did something unusual: he wrote his own job description and asked to become the agency's first sustainability director. Wieden+Kennedy gave him the job, and in 2023, the agency became the first global advertising network to achieve B Corp certification across all nine offices in seven countries. With brands spending over $700 billion annually on advertising worldwide, the messages agencies craft shape not just what people buy, but how they think about consumption itself.

Luke discusses how he sold sustainability as a business value proposition rather than a compliance issue, why he reports to the CFO instead of the CMO, and how Wieden+Kennedy's carbon removal program for video productions is changing industry standards. He also tackles thorny questions about greenwashing that can guide which clients agencies should work with, arguing that guiding any company toward sustainability is better than refusing to engage.

He shares lessons from helping transform Danish Oil and Natural Gas into Ørsted, one of the world's leading renewable energy companies, and explains why authentic storytelling beats green leaves and clichés every time. Can advertising agencies avoid greenwashing while still growing their clients' businesses? And what does it mean when sustainability becomes culture rather than just compliance?You can learn more about Wieden+Kennedy's sustainability work at wk.com.

Terraformation CEO Yishan Wong On Reforesting 3 Billion Acres
Most Silicon Valley CEOs who cash out their stock options start another tech company. Yishan Wong planted trees instead. After helping build PayPal, Facebook, and serving as Reddit's CEO, Wong concluded that humanity's biggest challenge wouldn't be solved with algorithms or network effects—it would be solved by restoring the planet's forests at an unprecedented scale. Mitch Ratcliffe sits down with Wong to discuss Terraformation, the company he founded in 2020 with an audacious mission: restore 3 billion acres of native forest worldwide—an area larger than the entire United States.

Planting a trillion trees isn't just about seeds in the ground. It's about solving bottlenecks like funding gaps that leave 95% of qualified forestry teams without resources, seed shortages, lack of infrastructure and technology, gaps in tracking and verification. Terraformation built a support system that includes modular seed banks, solar-powered nurseries, open source forest management software, which is called Terraware and a seed to carbon forest accelerator that's modeled on tech startup accelerators. Since founding Terraformation, Wong has enabled the planting of over 4.7 million trees across 394 species, established 19 seed banks and 21 nurseries and created more than 798 jobs. 

"We made Terraware not because this is the most genius piece of technology that will change the world," Yishan explains. "We said, hey, let's just help forestry teams achieve certain basic necessary activities." Unlike commercial timber plantations that prioritize fast-growing monocultures, Terraformation focuses on biodiverse native forests. Native tree species can support an order of magnitude more life than non-native species because they've co-evolved over millions of years. "Trees are the anchor species for a forest ecosystem," he added. "What you're doing is you're growing trees as the anchor species so that all of the other life in that forest ecosystem comes back."

Terraformation recently won the Keeling Curve Prize and the G20's RestorLife Award. The company also received recognition at the Global Sustainability Awards, winning SME Company of the Year. Yishan explains why a former Reddit CEO believes in low tech solutions that are the right approach to climate change, how Silicon Valley's lessons about scaling systems could apply to reforestation and what it takes to build an organization designed to be replicated rather than defended. You can learn more about the company at Terraformation.com.

The Climate Action Network's Pre-COP30 Briefing with Rebecca Thissen
Ten years after the Paris Agreement, the world's climate negotiators will gather in Belém, Brazil this November for COP 30, a summit many are calling a critical juncture for global climate action. After COP 29 in Baku ended with what developing nations called a woefully inadequate $300 billion annual commitment—far short of the $1.3 trillion economists say is needed—can multilateral climate negotiations still deliver the justice and transformation the climate crisis demands? And with 71% of climate finance currently provided as loans rather than grants, how is the debt crisis crushing developing countries' ability to invest in climate action?

Rebecca Thissen, Global Advocacy Leader for Climate Action Network International, joins Sustainability In Your Ear to unpack what's really at stake in Belém. With a background in International Public Law and years in the trenches of climate justice advocacy, Thissen works at the intersection of finance, economics, and climate action to ensure money flows where it's needed most. She discusses the just transition work program, Brazil's controversial Tropical Forests Forever Facility, the International Court of Justice's groundbreaking ruling on climate obligations, and why only 10% of countries showed up with their nationally determined contributions. Climate Action Network represents nearly 2,000 organizations across 130 countries, making it the world's largest coalition working on climate change. You can follow their daily updates during COP 30 through their newsletter ECO at climatenetwork.org.

Buckstop's Alexander Olesen Digs Into Urban Mining
Every solar array, battery system, and EV charger installed over the past decade will eventually need to be decommissioned. Yet there's no unifying system to handle that flow of materials—no operating system for the reverse supply chain that the circular economy depends on. While Americans recycle 97% of vehicles, we recycle less than 20% of electronics, leaving valuable critical minerals like lithium, cobalt, and gold to languish in warehouses or end up in landfills. The electronics embedded in our built environment represent the richest mining scene on Earth, yet we treat these refined materials as waste rather than the valuable resources they are. Meet Alexander Olesen, co-founder and CEO of Buckstop, an urban mining company launched in early 2025 to build what he calls "the intelligence layer for the circular economy." He previously founded Babylon Micro Farms, which develops distributed vertical farming systems, and he returns to Sustainability In Your Ear to share his new mission: creating a sustainable end-of-use solution for every electronic device on Earth.

Buckstop took just three months to deploy its "algorithmic assay," a method of deconstructing finished goods into their raw materials and critical minerals at scale, something that wasn't possible to do efficiently before the advent of AI. The result: asset owners can now see the granular value of their deployed electronics in unprecedented detail. The scrap value of electronics typically yields only 1-5% recovery, but resale value can reach 20-30%. For Fortune 500 companies with billions in fixed assets, that circularity delta represents enormous value currently being destroyed.

Olesen's approach draws directly from his decade-long experience as an OEM manufacturing vertical farming equipment with 1,200 unique components. "Why is there no comprehensive end-of-life solution for technology assets?" he asked. Every hardware entrepreneur he knew in renewables, robotics, and distributed systems faced the same problem. 

Buckstop's model draws inspiration from an unlikely source: Kelley Blue Book. "Kelley Blue Book was the data stream that formalized the aftermarket for vehicles," Olesen notes. Before that standardization, people would leave cars rusting by the roadside. Today, the automotive industry is the most circular industry on the planet. Olesen believes the same transformation is possible for the electronics industry. The platform currently focuses on renewable energy infrastructure—solar panels, batteries, inverters—but Buckstop's long-term vision extends to one day tracking all electronic assets. As Olesen puts it: "If you can't measure it, you can't improve it." That measurement is where circularity begins.

Sustainability In Your Ear: Culligan CEO Scott Clawson Maps The Future Of Water
Read a transcript of this episode. Subscribe to receive transcripts.

Turn on any faucet in America, and chances are the water meets federal safety standards. Yet Americans buy 50 billion single-use plastic water bottles annually—enough to circle the Earth 200 times if laid end to end. The bottles take 450 years to decompose, and recent research found that a single liter of bottled water can shed up to 240,000 pieces of microplastic that we ultimately consume. Meanwhile, 37% of global drinking water remains contaminated, with PFAS "forever chemicals" and lead appearing even in neighboring homes on the same street. Meet Scott Clawson, Chairman and CEO of Culligan International, the nearly 90-year-old company that's become the global leader in water services by making filtered water more accessible than single-use plastic. Under Clawson's leadership, Culligan serves 170 million people worldwide, and the company's filtration systems have helped avoid the use of 45 billion plastic bottles annually. 

The company has set ambitious targets: achieving net positive water impact by 2050 and cutting scope one and two emissions intensity by 40% before 2035. After completing WAVE water stewardship verification, Culligan discovered that even testing filtration equipment was wasteful, leading the company to develop dry-testing methods that eliminate water waste before machines reach consumers. The company has electrified 25% of its fleet and donated 9 million liters of water to communities in need in 2024 alone. Clawson's approach to sustainability isn't just operational—it's personal.

A decade ago, while vacationing in the Bahamas, he encountered a beach covered in plastic waste. "That's when my inner balance was sparked to make sure we do more than just use our planet to make money, but let's use our planet to help it be a better place to live," he recalls. As water scarcity intensifies globally, Clawson believes the consumer holds the power: "Every time you pick something up off the shelf, you are voting. You're sending a signal to a company." His message is clear—test your water, understand what's in it, and invest in point-of-use filtration rather than contributing to the plastic crisis.You can learn more about Culligan International at culliganinternational.com.

Terracycle Founder Tom Szaky On Building A Service-Centered Circular Economy
Read a transcript of this episode. Subscribe to receive transcripts.

For decades, our relationship with waste has been defined by disposability and denial. The disposability of everything from coffee cups and cigarette butts to smartphones, and the denial about where it all goes when we're done with it, means that humans generate over 2 billion tons of waste globally each year, with Americans alone throwing away 290 million tons of waste annually. The convenient fiction is that recycling solves the problem. But the reality is starkly at odds with that comforting idea, and today we explore the challenge with a recycling innovator. Meet Tom Szaky, founder and CEO of TerraCycle, who has spent over 20 years proving that what is considered impossible to recycle is really just unprofitable to recycle—by making the hard-to-recycle profitable. Terracycle has tackled some of the world's most challenging waste streams, like dirty diapers, cigarette butts, chewing gum, and composite packaging that municipal recyclers cannot handle profitably. TerraCycle now operates in over 20 countries.

Even as TerraCycle proves that many materials can be recycled with the right economic model, Tom has concluded that recycling alone won't solve waste at its root cause, which led to the launch of the reusable packaging-based consumer good service Loop, which offers reusable packaging at stores in the U.S., Britain, and France. This realization led Tom to the conclusion that the waste crisis isn't just about recycling better, it's about redesigning our consumption. Historically, humans have made a mess. Every archaeological site has found waste piles, or what are called middens, alongside human settlements. However, other social species also pile up waste, as well as their dead, in middens. But we needn't bury ourselves in waste just because humans have always produced trash, as Tom explains, the economics of recycling have limited its success and at a time when we could not track and manage materials, such as during the explosion of trash during the consumer revolution of the 1950s we didn't have the logistical technology to address the many different materials in our garbage cans, but now we do from scannable codes to optical scanners that sort materials on high speed conveyor belts at materials recovery facilities (MRFs). Terracycle's pricing today reflects the cost of recycling a material when collection and sorting services, along with localized processing capacity, are not...

Sustainability In Your Ear: Heather Terry's Regenerative Journey At GOODSam Foods
The global food system stands at a crossroads. Climate change is reshaping where crops can grow, trade disputes threaten supply chains, and smallholder farmers who produce much of our food often have the least power in the system. Meet Heather Terry, founder and CEO of GoodSAM Foods, and discover how the company is transforming the traditional smallhold farm model by putting people and regenerative agriculture at the heart of a growing food company. GoodSAM Foods sources 90% of its ingredients directly from smallholder farms in Latin America and Africa, eliminating middlemen and reinvesting profits into farming communities. Terry's approach is both principled and pragmatic: as climate volatility reduces crop yields globally, the companies that have built genuine relationships with farmers will have access to limited harvests. "When I'm a farmer and I suddenly have leverage, who am I going to sell that product to?" Terry asks. "It's relationships."[

Terry's journey to raise $9 million in Series A funding over 18 months illustrates the disconnect between traditional investors and regenerative business models. After facing skepticism from conventional CPG investors, she found success with impact investors who understood that sustainable food systems represent the future of the industry. While GoodSAM maintains USDA Organic and Non-GMO Project verification, Terry takes a critical stance on regenerative certification labels, arguing that current systems impose Global North standards on farmers who have practiced regenerative techniques for generations. Instead, GoodSAM focuses on direct relationships and on-ground verification. Her proactive approach protected both the company and its farming partners from sudden economic shocks at a time when the U.S. food system faces mounting pressures from climate impacts and trade policy changes. "Every time you pick something up off the shelf, you are voting," Terry said. "You're sending a signal to a company."

SePRO's Mark Heilman On Phosphorus, Waterways, And Invasive Species
Every summer, the same devastating story repeats across America: lakes that families have cherished for generations suddenly turn toxic green. Half a million people in Toledo lose their drinking water when Lake Erie blooms with poison algae. Or, Florida's red tide costs the state billions in lost tourism. But some of the most damaged bodies of water in America are getting a cleanup. Meet Dr. Mark Heilman, Vice President of Environmental Restoration and Advocacy at SePRO, whose two decades of water restoration work have brought 1.4 million acres of polluted lakes and wetlands across North America back to life. Mark's team achieved a 42% reduction in harmful phosphorus levels and protected $300 million in annual tourism revenue at Moses Lake, Washington.

When phosphorus from fertilizers and runoff enters our waters, it acts like Miracle-Gro for algae, creating massive blooms that choke aquatic life and produce toxins that cause liver damage, neurological problems, and even death. U.S. Environmental Protection Agency assessments show the number of overly productive lakes with poor water quality is increasing. Harmful algal blooms are becoming more frequent and intense. Perhaps most striking is Heilman's noting that even benign-seeming weekend lawn care directly contributes to this crisis: a bushel of grass clippings that reach a waterway contains about a tenth of a pound of phosphorus, the same amount found in a box of Miracle-Grow fertilizer. When dumped into a waterway, those clippings can grow up to 50 pounds of algae. Heilman explains that treating a lake is like "performing surgery on an entire ecosystem," a process that involves a comprehensive assessment of water quality, community engagement, and multi-year management programs. The climate crisis is intensifying these challenges as warming water temperatures favor cyanobacteria growth, while invasive species like hydrilla—what Heilman calls "disturbance specialists"—exploit changing environmental conditions to establish footholds and outcompete native species. Yet he remains optimistic about prevention: "It's easier to prevent, takes less resources and investment to prevent them than to actually try to resolve them once these problems are in the environment."

Author and Activist Bill McKibben Brings The Sun
Solar and wind have become the cheapest sources of power in human history, but political headwinds threaten to derail the fastest energy transformation ever recorded. At this crucial juncture, how do we ensure America doesn't surrender its technological leadership in clean energy to nations more willing to embrace the future? Meet Bill McKibben, legendary environmentalist and author whose four decades of climate writing have shaped our understanding of the environmental crisis. His latest book, Here Comes the Sun, argues that we're standing at the hinge of history. In 2024, 92% of new global electricity generation came from renewables, and the U.S. saw greater gains, at 96% of new generation capacity. McKibben, founder of 350.org and Third Act, believes we can fundamentally reshape how civilization powers itself if we look forward to energy abundance rather than backward to fossil fuel scarcity.

The numbers are stunning, but the transition isn't guaranteed. McKibben warns that while the adoption of renewable energy is inevitable due to economic forces, it may not occur quickly enough to prevent catastrophic climate change. That's why he's organizing Sun Day, a national day of action on September 21st, designed to drive renewables out of the "alternative" category once and for all. Once solar panels are installed, McKibben explains, "the sun pleasantly delivers the energy for free over and over and over and over again." That's a paradigm shift from buying energy as a commodity that could reshape not just our power grid, but geopolitics itself. While partisan politics may divide Americans on climate change, polling shows both conservatives and liberals support solar power—albeit for different reasons. His conservative neighbors embrace energy independence and self-reliance, while liberals appreciate the environmental benefits. "Even humans are going to be hard pressed to figure out how to start a war over sunshine," McKibben notes.

You can learn more about Bill McKibben's work at BillMcKibben.com and Sun Day events at Sunday.Earth. "Here Comes the Sun" is available on Amazon, at Powell's Books, and in local bookstores.

Sustainability In Your Ear: Carbonfuture is Building the Trust Infrastructure for Carbon Removal
The carbon removal industry stands at a crucial crossroads. While cutting emissions remains essential, avoiding catastrophic warming now requires pulling billions of tons of CO2 from the atmosphere permanently. But as this nascent field grapples with questions of legitimacy, scalability, and accountability, a critical challenge remains: How do we build the infrastructure needed to track, verify, and certify that carbon has actually been removed and stays removed? Meet Hannes Junginger-Gestrich, CEO of Carbonfuture, a company helping define the monitoring, reporting, and verification (MRV) infrastructure that could transform carbon removal from scattered efforts into a functioning ecosystem. Launched five years ago, Carbonfuture has emerged as what CDR.fyi describes as "the largest facilitator of durable carbon removal" by volume. The company's digital platform integrates data across the carbon removal life cycle, connecting diverse approaches like biochar, enhanced rock weathering, and direct air capture with buyers seeking to meet climate commitments. "We are probably more the crowd, the ground keepers in a stadium that makes sure that everything is provided properly," Hannes explains, using a sports analogy to describe their role: "We are the ground keepers in a stadium [who ensure] the players have a playing field that's in shape and no one gets hurt, and the audience can come and they pay their tickets and have a good experience."

The MRV infrastructure becomes crucial as corporate demand for verified carbon removal grows and trust becomes currency. One of the most interesting aspects of the conversation centers on balancing data confidentiality with transparency needs, particularly when collecting data along industrial value chains from agricultural residue producers to biochar processors to end users. Perhaps most telling is Junginger-Gestrich's unwavering commitment to scientific rigor over short-term economic gains: "We never had to trade off between rigor and allowing a not so good project on our platform for economic reasons. We always lean to the scientific and rigorous side." This philosophy has guided Carbonfuture's work with leading buyers like Microsoft, helping develop increasingly sophisticated approaches to carbon removal verification. While Junginger-Gestrich expresses concern about delayed emission reductions globally, he remains optimistic about carbon removal scaling: "I think we will be on the path to the gigatons by 2040 for sure." His vision emphasizes ecosystem thinking over vertical integration, aiming to drive down costs while creating network effects that could accelerate the entire field. As governments worldwide grapple with climate policy, the monitoring, reporting, and verification systems companies like Carbonfuture are developing now may well determine the success of our collective effort to reverse climate change.

Sustainability In Your Ear: Author Topher McDougal Asks If Earth Is Evolving A Planetary Consciousness
What if Earth is developing a planetary collective intelligence emerging from the convergence of ecological crisis, new global information systems, and the data-crunching capabilities of artificial intelligence? This provocative question drives economist Topher McDougal's book, Gaia Wakes: Earth's Emergent Consciousness in an Age of Environmental Devastation. On this episode of Sustainability In Your Ear, explore McDougal's sweeping theory that our planet may be in the early stages of developing what he calls a "Gaiacephalos"—a planetary consciousness that could fundamentally reshape humanity's role in the global ecosystem. McDougal opens his book with a striking metaphor from Star Trek: The Next Generation, where the Enterprise's computer systems flicker into sentience, its emerging "personality" acting out disagreements in the holodeck that nearly destroy the ship. That episode, McDougal argues, mirrors our current moment. As environmental devastation accelerates and technologies become increasingly networked, we may be witnessing the birth pangs of a planetary intelligence that could guide us toward survival or react chaotically to the damage humans have caused.

Building on James Lovelock's Gaia hypothesis, which views Earth as a self-regulating living system, McDougal explores the profound and unsettling implications of Gaiacephalos. What is humanity's role? Noting a paradox in human development, that societies have become increasingly peaceful at the expense of massive environmental degradation, McDougal discusses how concepts like "progress" and "free will" might change in a world governed by an emergent planetary intelligence. Drawing on ancient myths—from Hopi legends to the Tower of Babel—McDougal uses traditional stories as lenses for understanding global transformation. Throughout our conversation, he repeatedly references the work of René Descartes and how his mind-body split has defined Western thinking since the Enlightenment. He argues that this mechanistic view prevents us from understanding emerging systems holistically—whether we're talking about AI, collective intelligence, or planetary consciousness. We keep separating the physical system that performs calculations from the experience of thought itself, missing the integrated whole. Consequently, becoming "indigenous to our times" offers a path forward. Rather than appropriating Indigenous ways of life, he suggests we need to learn how to live fully in relationship with our current systems and places. True indigeneity means understanding our role within larger systems and, as the apex predator currently destroying the ecosystem we depend on, being thoughtful about our interactions within that system.What if Earth is developing a planetary collective intelligence emerging from the convergence of ecological crisis, new global information systems, and the data-crunching capabilities of artificial intelligence?

Sustainability In Your Ear: Author Kelsey Timmerman's Journey to Find Farms Regenerating Earth
The scale of agriculture's environmental impact is staggering. According to the EPA, agricultural runoff is the leading cause of degraded water quality in rivers and streams. Today's farming practices lead to 1.70 billion tons of U.S. topsoil annually, and agriculture produces 31% of human greenhouse gas emissions. Tune in to meet Kelsey Timmerman, author of the new book, Regenerating Earth, from Patagonia Books, who faces a heartbreaking reality shared by many rural families: he can't let his children swim in the pond near their Indiana home because of agricultural contamination. Rather than accept environmental degradation as inevitable, Kelsey embarked on a global journey to find farmers and communities who prove there's another way. From standing barefoot in traditional Hawaiian kalo patches to protecting cattle from lions alongside Maasai warriors in Kenya to discovering how chocolate could save Brazilian rainforests, he found regenerative agriculture practices that build soil, sequester carbon, and challenge everything we think we know about farming. 

Kelsey's story revolves around systems thinking that connects everything from chloroplasts to mycorrhizal fungi with how we eat. He argues that industrial agriculture leads to farmers being farmed by corporations, trapping them in debt to buy chemically treated seeds, fertilizer, herbicides, and fungicides. His journey uncovered regenerative practices rooted in Indigenous and traditional farming practices combined with cutting-edge soil science. Farming can be more profitable for farmers who heal the land. The solutions aren't new. They're already in hand but largely ignored or forgotten because they require attention to nature's complexity rather than simplifying life to fit profit margins. Regenerative thinking starts by approaching problems through the same lens that nature does, by putting everything to use and accounting for all positive and negative impacts while treating nothing as waste to be discarded. For consumers, this means understanding that grocery choices ripple through complex ecological networks, with practical steps starting at farmers markets and supporting farms that regenerate rather than degrade the land which you can find using the Farm Map at https://regenerationinternational.org/.

Sustainability In Your Ear: USEFULL's Rob Kutner On Easing Reuse Adoption With Plastic Buy-Backs
The scale of our plastic waste crisis is staggering: the U.S. alone uses over 100 million plastic utensils every day, most of which are used once and tossed into landfills where they'll persist for centuries. From ocean pollution to overflowing campus dumpsters after lunch rush, single-use packaging defines modern food service—but universities and businesses are under mounting pressure to embrace sustainable alternatives. Tune in to a conversation with Rob Kutner, Chief Revenue Officer at USEFULL, which offers a practical solution to food service waste: a reusable takeout container system designed for the high-volume and fast pace of college cafeterias. USEFULL's latest move challenges throwaway culture head-on with a plastic buyback program that pays institutional cafeterias to ditch disposables and go reusable.  

The company has already made waves at universities like the University of Pittsburgh, Emory University, and the University of North Carolina Wilmington, achieving a remarkable 99% return rate for their containers. The economics are compelling. Rather than asking institutions to absorb the cost of switching to sustainable packaging, USEFULL creates financial incentives by purchasing a cafeteria's existing plastic inventory, removing the sunk costs barrier and providing immediate value to cafeterias ready to make the transition. USEFULL built an ecosystem to improve the convenience of reuse, developing tracking systems, POS integration services, and local washing and inventory management to solve the campus reuse challenge. The timing couldn't be better. As Bain & Company recently reported, ROI has become the driving force for growing adoption of sustainable practices. As companies recognize the threat to future business performance represented by the take-make-waste economic model, USEFULL demonstrates how simple steps, not grandiose plans for revolution, can create tractable, attractive, and profitable paths to reduced waste.

Sustainability In Your Ear: Carbon Direct Chief Scientist Julio Friedmann on the Path to Carbon Removal
The scale of our climate challenge is staggering: humans have pumped 1.6 trillion tonnes of carbon dioxide into the air and oceans since 1750, and we're adding another 40 billion tonnes every year. Even with dramatic emissions reductions, we're still on track to blow past 1.5 degrees of warming, the Paris Accord target first breached in 2024. Tune in to a conversation with Dr. Julio Friedmann, Chief Scientist at Carbon Direct. This carbon management company partners with Fortune 500 companies such as Microsoft, JPMorgan Chase, and American Express to transform net-zero commitments into science-backed action plans. After a career that began as a researcher at ExxonMobil and included service at Lawrence Livermore National Laboratory, Columbia University's energy policy center, and running advanced energy programs in the Obama administration's Department of Energy, Julio brings unique expertise to the intersection of massive climate challenges and current technological capabilities. 

As companies work toward 2030 and 2050 carbon goals, the question isn't whether we'll need massive carbon removal—it's whether we can deploy it fast enough and fairly enough to matter. The recent $100 million XPRIZE Carbon Removal awards highlighted the diversity of approaches being pursued, with natural solutions like enhanced rock weathering using basalt and azomite soil, and biochar applications to farmland dominating the winners. But how do these technologies stack up against the hype? Friedmann provides a realistic assessment of where Direct Air Capture, ocean alkalinity enhancement, and other carbon removal approaches stand today. Carbon Direct's team of 70+ scientists changes the conversation with corporate clients about their carbon strategies, providing the scientific firepower to offer hard feedback about what's needed to preserve the markets, supply chains, and revenue streams companies depend on.

Earth911 Podcast: Kelly Ramsey on Life as a Hotshot Firefighter and the Burning Reality of America's Wildfire Crisis
What does it take to stand on the front lines of one of the most dangerous and increasingly common realities of our climate crisis era? Discover the intense world of elite wildland firefighting with Kelly Ramsey, the first woman in about a decade to join the Rowdy River Hotshots, a pseudonymously named, California-based crew of highly trained wildland firefighters. In this episode of Earth911's Sustainability In Your Ear, Kelly shares insights from her powerful new memoir, Wildfire Days: A Woman, a Hotshot Crew, and the Burning American West, which chronicles her transformative two years fighting fires and discovering herself in the process. Her journey into the masculine world of hotshot crews offers a unique perspective on who becomes one of these ultimate first responders, exploring not just the Marine-style training and intense physicality required, but also the personal transformation that comes from confronting both literal and metaphorical fires.

As we head into 2025, the conversation takes on urgent relevance, with budget cuts reducing the number of available firefighters despite wildfires growing more severe by the decade. 1,600 firefighters have been laid off this year, despite a growing need. Kelly explains the concept of Preparedness Level 5, when there are no crews left at the time fire danger peaks, and warns that understaffing could leave the nation operating at this dangerous level for much of the upcoming fire season. She also addresses the psychological and physical toll of this extreme profession, the sobering reality of firefighter mortality. She also offers practical advice for those living in wildfire-prone areas on home hardening and evacuation preparedness. Tune in to hear Kelly's powerful story of transformation, resilience, and the urgent need to support our wildfire fighting forces. Learn more about Kelly and Wildfire Days at kellylynnramsey.com.

Earth911 Podcast: Implasticfree.com's Simona Paganetto on Building a Plastic-Free Marketplace One Brand at a Time
What if the solution to our plastics crisis isn't just about individual behavior change but building entirely new marketplaces that make plastic-free living accessible and transparent? On this episode of Earth911's Sustainability In Your Ear, discover the grassroots approach with Simona Paganetto, founder of Implasticfree.com, who has transformed her search for plastic alternatives into a curated directory of nearly 150 vetted brands committed to ditching plastic packaging and single-use products. What began as Simona's journey toward plastic-free living has evolved into a store that bridges the gap between conscious consumers and genuinely sustainable brands. Her rigorous vetting processes and careful curation has made Implasticfree.com a trusted resource for shoppers navigating the confusing landscape of sustainability claims and greenwashing.

Simona's approach differs from typical environmental activism—she's learning digital marketing while building her mission-driven venture, creating a refreshingly authentic take on environmental entrepreneurship that prioritizes transparency and continuous learning over having all the answers. We also explore the psychological barriers people face when trying to go plastic-free, from the perception that sustainable products are always more expensive to the overwhelming nature of changing deeply ingrained habits.

Earth911 Podcast: Terviva’s Marc Diaz Introduces the Pongamia, a Tree for the Climate Crisis
As climate change accelerates and traditional crops face mounting pressures from drought, extreme weather, and soil depletion, innovative solutions are emerging from unexpected sources. Explore the soil-restoring potential of the pongamia tree with Marc Diaz, Chief Commercialization Officer at Terviva, an agtech company that has spent over a decade unlocking this hardy species’ dual capabilities as a nutritious food source and sustainable fuel feedstock. Through their Ponova platform, Terviva is demonstrating how pongamia can restore degraded agricultural land while building equitable supply chains that empower smallholder farmers, particularly women in India, with above-market wages and technical support. The tree’s versatility extends beyond environmental benefits. Pongamia beans are rich in both protein and oil, positioning them as valuable ingredients for food applications while simultaneously serving as feedstock for biodiesel and sustainable aviation fuel.

Marc explains how pongamia’s nitrogen-fixing properties improve soil health over time, making it ideal for regenerative agriculture practices, while its protein- and oil-rich beans serve as valuable ingredients for both food applications and biofuel production. With recent partnerships involving Chevron Renewable Energy Group and Japan’s Idemitsu scaling pongamia cultivation for sustainable aviation fuel, and expansion into citrus-depleted regions of Florida and California, this versatile tree exemplifies the kind of adaptive, multi-purpose approach needed for climate-resilient agriculture. He also shares insights into what farmers need most when transitioning to climate-resilient crops: technical support, financial backing, and education about new cultivation methods. By addressing these needs while placing equity at the center of their business model, Terviva is proving that commercial success doesn’t require compromising social impact.Tune in to discover how one species is helping reimagine food and fuel systems for a changing world, and learn more at terviva.com and ponovafoods.com.

Earth911 Podcast: B-SIDES Founder Yousuf Ahmed Introduces the Upcycled Crunch Puffs Snacks Strategy
What if the ingredients discarded daily in food production could become the foundation of a more sustainable food future? On this episode of Earth911's Sustainability In Your Ear,  discover the pragmatic vision with Yousuf Ahmed, founder of B-SIDES, a Brooklyn-based startup, proving that upcycled snacks can be delicious and environmentally responsible. Inspired by tasting a single slice of spent grain bread in 2014, Yousuf transitioned from finance and music to food innovation, launching B-SIDES to bring upcycled, plant-based snacks into the mainstream. The company's flagship product, Crunch Puffs, transforms oat pulp—typically discarded during oat milk production—into protein-rich, allergen-friendly snacks packaged in home-compostable materials. From sourcing pulp from small Midwest oat milk makers to manufacturing in Canada and selling through Amazon and New York indie grocers, B-SIDES is creating a playbook for how small brands can lead on both climate action and culinary creativity.

Yousuf shares the technical challenges of working with oat pulp as a primary ingredient and the complexities of achieving a moisture seal with home-compostable packaging. We explore how his background in finance and music has influenced his approach to food startups, including the trade-offs between local production and proximity to raw materials, as well as strategies for positioning upcycled food to sustainability-conscious consumers. As Yousuf emphasizes, sustainable products must deliver on taste and price to succeed in the market—environmental benefits alone aren't enough. His pragmatic approach offers valuable lessons for entrepreneurs: real market-winning products that can change manufacturing's negative impacts while sustaining profitable companies must compete on quality first, with sustainability as an added benefit rather than an excuse for inferior performance. You can find B-SIDES Crunch Puffs on Amazon and at select retailers. Learn more about the company at enjoybsides.com.

Earth911 Podcast: The Carbon Removal XPRIZE Winners
As the world confronts the urgent challenge of removing billions of tons of carbon dioxide from the atmosphere, breakthrough innovation is essential to scale solutions fast enough to meet global climate goals. On this episode of Earth911's Sustainability in Your Ear, discover the groundbreaking results of the $100 million XPRIZE Carbon Removal competition, a four-year competition among 1,300 teams from 88 countries that represents one of the most ambitious efforts to catalyze carbon removal innovation. We're joined by Nikki Batchelor, Executive Director of XPRIZE Carbon Removal, and Michael Leitch, Senior Technical Lead for the competition, to discuss what may be one of the most consequential moments in carbon removal innovation to date. They discuss how the competition's $100 million scope and multi-year timeline attracted breakthrough solutions and outline plans for continued engagement with the winning teams as they scale their innovations.[

Kenya-based Mati Carbon claimed the $50 million grand prize with an enhanced rock weathering approach that spreads finely ground volcanic rock on farmland, simultaneously capturing atmospheric carbon while improving soil health for local farmers. Mati Carbon's victory wasn't just about technical innovation; it demonstrated a cost-effective approach that delivers multiple benefits in Kenya and India's smallholder farming communities. Three runners-up—NetZero, Vaulted Deep, and UNDO—each received $5 million for their distinct approaches, which spanned biochar production, underground carbon storage, and large-scale mineral spreading.

In 2024 alone, humans released 41.6 billion tons of CO2 into the atmosphere, adding to approximately 1.5 trillion tons emitted since the Industrial Revolution. Current carbon removal projects operate at a kiloton scale and must rapidly expand to millions of tons annually. The goal isn't merely offsetting new emissions—it's achieving net-negative emissions to reverse the climate damage already done, albeit slowly. Learn more about the XPRIZE Carbon Removal competition and other grand challenges at xprize.org. Watch the documentary series about the competition and winners on the XPRIZE Carbon Removal YouTube channel.

Earth911 Podcast: Brenna Simmons-St. Onge is on a Regenerative World Quest
On today's Sustainability In Your Ear, meet Brenna Simmons-St. Onge, a systems strategist, regenerative futurist, and founder of B the Light Consulting, as we explore her family's extraordinary three-year journey around the world. The Regenerative World Quest isn't your typical travel adventure; it's a deliberate mission to identify, amplify, and help replicate Earth's most promising regenerative communities and projects. From Costa Rica to South Africa, she and her family engage with leaders, learn from Indigenous knowledge holders, and discover models that regenerate land, restore community agency, and reconnect people to purpose. Brenna's aim is to demonstrate how regeneration—not just mitigation—can serve as our organizing principle for addressing the climate crisis.

Rather than extracting experiences as tourists, Brenna and her family integrate into the places they visit, contributing through forms of meaningful exchange. Her key insight is that true abundance comes from within—our creativity, generosity, and the love we share with others and the planet. Thee regenerative communities she's visited focus on building a prosperity based on relationships, ecological health, and community resilience rather than accumulating material possessions. The Regenerative World Quest will culminate in a documentary series and practical playbook that others can use to live more lightly on the planet, thinking seven generations ahead following Indigenous traditions. To follow Brenna's journey and learn from the regenerative communities she discovers, visit https://bthelightconsulting.com/ or follow her on LinkedIn, Instagram, Facebook, and YouTube.
