• Author and Activist Bill McKibben Brings The Sun
    Sep 8 2025
    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.

  • Sustainability In Your Ear: Carbonfuture is Building the Trust Infrastructure for Carbon Removal
    Sep 1 2025
    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
    Aug 25 2025
    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
    Aug 18 2025
    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/. You can learn more about Kelsey's work at kelseytimmerman.com and Regenerating Earth is available on Amazon, Powell's Books, and local booksellers.

  • Sustainability In Your Ear: USEFULL's Rob Kutner On Easing Reuse Adoption With Plastic Buy-Backs
    Aug 11 2025
    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
    Aug 4 2025
    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
    Jul 7 2025
    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.
