S2E67: The Carbon Takeback Obligation & carbon removal—w/ Margriet Kuijper
What would happen if businesses were expected or even required to store a tonne of carbon for every tonne of carbon they produce? A Carbon Takeback Obligation is a policy framework that aims to make that the new standard. Today we learn more about how such a system might operate.
Margriet Kuijper is a former civil engineer for Shell, where she focused on the development of carbon capture and storage projects. Today, she serves as an independent consultant working on a Carbon Takeback Obligation, otherwise known as CTBO. On this episode of Reversing Climate Change, Margriet joins Ross to share the simple idea behind a Carbon Takeback Obligation and explain how it addresses the common concerns associated with oil and gas carbon capture projects.
Margriet discusses how CTBO makes polluters pay to clean up their emissions and describes how CTBO policy could work in tandem with a carbon tax or emissions trading system, incentivizing both emitters and producers to find solutions together. Listen in to understand Margriet’s take on the role of offsets under CTBO and in a net-zero world, and learn how businesses would benefit from the long-term policy certainty of a Carbon Takeback Obligation.

S2E64: How to Be Animal: a guide for confused humans—w/ Melanie Challenger, author
The narrative of human exceptionalism posits that there is something unique about being human that makes us more valuable. And we believe that what matters most are the things that seem to separate us from animals—like our ability to reason or the immortal human soul. But what if you can’t separate the animal part of us from our spirit? What if being human IS being animal?
Melanie Challenger is a writer of environmental history, podcast host of Enter the Psychosphere, and author of the new release, How to Be Animal: A New History of What It Means to Be Human. On this episode of Reversing Climate Change, Melanie joins Ross to share her argument against substance dualism, explaining why we can’t separate the idea of being human from that of being animal.
Melanie offers insight on how we can ‘become animal’ without reverting to amoral, self-serving behaviors and why she sees the simple, clean messaging around environmental issues as being problematic. Listen in to understand Melanie’s take on the human battle with mortality and learn to accept that life is finite but not fear death.

Grounded: A Fierce, Feminine Guide to Connecting with the Soil—w/ Dr. Erin Yu-Juin McMorrow, author
Are we out of balance? Some thinkers pose that the scales have tipped toward industry, ego, and individuality, and we’re disconnected from the cycles of nature. We’re all Yang and no Yin. And this imbalance is causing climate change. So, what can we do to restore our sense of interconnectedness among all living things? How can tapping into our spirituality help us heal ourselves and the earth?
Dr. Erin Yu-Juin McMorrow is the author of Grounded: A Fierce, Feminine Guide to Connecting with the Soil and Healing from the Ground Up. She is also a founding member of Kiss the Ground, a nonprofit dedicated to awakening people to the possibilities of regeneration. On this bonus episode of Reversing Climate Change, Dr. McMorrow joins guest host and Nori cofounder Alexsandra Guerra to share her mother metaphor for the soil, describing how she sees the Yin as the feminine energy of regeneration and why western society struggles with birth and death—the primary portals of transformation.
Dr. McMorrow explores how our desire to DO disregards the spiritual aspect of climate change, discussing the individual and collective healing we must do to activate our soul voice and reconnect with each other and the earth. Listen in to understand the relationship between the empowerment of women and soil health and learn Dr. McMorrow’s simple practices for connecting with spirit and bringing our natural systems back into balance.

S2E63: Carbon removal in the Biden Administration—w/ Dr. Jan Mazurek, ClimateWorks Foundation
In order to meet the goals of the Paris Agreement, we can’t just reduce emissions. We have no choice but to add carbon dioxide removal (CDR) to the mix to keep global temperature rise under 2°C. So, what CO2 removal processes are in development? And what are governments and nonprofits doing to advocate for and fund carbon removal?
Dr. Jan Mazurek serves as Senior Director at the ClimateWorks Foundation, where she leads the Carbon Dioxide Removal Fund. On this episode of Reversing Climate Change, Dr. Mazurek joins Ross to discuss what the Biden administration is doing to make ‘historic strides on climate’ and explain what carbon removal measures are left out of the Biden-Harris climate agenda.
Dr. Mazurek explores why it’s politically beneficial to lead with rural resilience and job opportunities as opposed to carbon removal, describing how ClimateWorks grantees partner with unions to garner support for DAC. Listen in for Dr. Mazurek’s insight on the challenges associated with carbon pricing and find out why it’s crucial to engage front line communities in the discussion around carbon removal.

S2E62: The Oxford Offsetting Principles & carbon removal—w/ Eli Mitchell-Larson
Many corporations, organizations, and governments have made net zero commitments, and most are leaning on voluntary carbon offsetting to achieve these climate goals. But how can we be sure that such carbon offsets demonstrate a real change in the atmosphere? And how can we approach offsetting in a way that gives rise to an actual net zero society?
Eli Mitchell-Larson is a climate researcher and PhD candidate at the University of Oxford and the corresponding author of The Oxford Principles for Net Zero Aligned Carbon Offsetting. He also serves as an advisor to Carbon Direct and is helping build a new carbon removal advocacy organization in Europe. On this episode of Reversing Climate Change, Eli joins Ross to walk us through Oxford’s four principles, explaining why the guidelines prioritize decarbonizing first and then negating emissions.
Eli describes why he advocates for a shift to carbon removal offsetting and long-lived storage, discussing why he believes nature-based solutions are crucial—but may not be appropriate for carbon markets. Listen in to understand the argument of why companies must support the development of net zero aligned offsetting (and what that might look like) and learn how you can get involved in Eli’s burgeoning advocacy organization that serves as a champion for carbon removal.

S2E61: Paul Greenberg on The Climate Diet: 50 Simple Ways to Trim Your Carbon Footprint
There’s a lot of advice on how reduce your carbon footprint. But everything seems to come with a caveat. You can stop eating meat, but do synthetic meats require monoculture? You can boycott Bitcoin, but would that make the grid itself any cleaner? You can drive an electric car, but its battery is made with rare minerals. So, how do you make choices that really move the needle?
Paul Greenberg is the fisherman and bestselling author behind Four Fish, American Catch, and The Omega Principle. His latest book is called The Climate Diet: 50 Simple Ways to Trim Your Carbon Footprint. On this episode of Reversing Climate Change, Paul joins Ross to explain what we can do to support sustainable fisheries and why we should be ‘picky plant eaters.’
Paul challenges us to be mindful of how many children we add to the planet and shares his argument against building infrastructure that gets us ‘back to normal’ after the pandemic. Listen in for Paul’s insight on electrical versus gas appliances and learn how The Climate Diet can help you make conscious choices in a spirit of kindness to the environment.

S2E60: Art out of thin (carbontech) air—w/ Madison Savilow of Carbon Upcycling & Expedition Air
Art has a unique ability to explain complex, oft-emotional topics in an understandable way. And that’s why Carbon Upcycling Technologies (CUT) is engaging with visual artists to educate the general public about carbontech. CUT offers their artist-collaborators free materials and tech support, encouraging the use of CO2-derived materials to create pieces that ‘showcase the carbon capture and utilization industry.’
Madison Savilow is the Chief of Staff at Carbon Upcycling Technologies and Venture Lead of CUT’s new consumer brand, Expedition Air. On this episode of Reversing Climate Change, Madison joins Ross to discuss the technology Carbon Upcycling uses to create solid materials like concrete, plastics, and consumer products out of CO2 and share her take on the tradeoffs associated with working with some of the largest players in the energy sector.
Madison explains what inspired CUT to launch Expedition Air, describing how a consumer brand helps educate the general public about carbontech and what other companies in the space are following suit. Listen in for insight into Expedition Air’s collaboration with artists Annalee Levin and Luis Merchan and learn how Madison and her team are using visual art to market carbontech.

Rebuilding trust in a polarized world—Dr. Kevin Vallier, philosopher at Bowling Green State University
According to the NOMINATE Index, the last time the US was this polarized was just before and during the Civil War. So, how did we get here? And what can the philosophy of public reason liberalism teach us about living together—even when we don’t agree on much?
Dr. Kevin Vallier is an Associate Professor of Philosophy at Bowling Green University and author of Trust in a Polarized Age and Must Politics Be War? Restoring Trust in the Open Society. On this episode of Reversing Climate Change, Dr. Vallier joins Ross to discuss the doom loop between falling distrust and growing polarization and address how we can learn to disagree in more a productive way.
Dr. Vallier explains liberalism in general and public reason liberalism specifically, describing how we might build a shared doctrine that appeals to multiple reasonable perspectives. Listen in for Dr. Vallier’s public reason argument for restricting carbon emissions and learn what we can do to rebuild trust in our institutions and each other.

S2E59: Is endless growth Crazy Town?—w/ Dr. Jason Bradford of the Post Carbon Institute
Empires rise and fall. And while we understand these cycles conceptually, there’s a bizarre notion that we are somehow immune. That we can continue to evolve toward greater ease and material abundance generation after generation. That our potential for growth is somehow unlimited. But natural resources are finite. So, what happens when we run out?
Dr. Jason Bradford is the Cofounder of Farmland LP and Cohost of Crazy Town, a podcast produced by the Post Carbon Institute that explores “climate change, overshoot, and runaway capitalism”. He is also the author of The Future Is Rural: Food System Adaptations to the Great Simplification. On this episode of Reversing Climate Change, Dr. Bradford joins Ross to explain what differentiates ecological economics from other schools of thought and why some resources are simply too valuable to price.
Dr. Bradford shares his prediction regarding a great simplification of civilization, describing his vision of a future where we might still enjoy modern conveniences but at a very different scale. Listen in to understand why we he thinks we can’t ‘artificial ecosystem’ our way on to other planets, why industrial carbon capture is a bad idea, and how we might build a lower-complexity society that is sustainable for the long term.
