When carbon credits come alive, literally


The novel begins not with carbon markets or policy jargon, but with a little girl drowning.

“‘Tragic moment when a seven-year-old girl is dragged away in a flash flood after a powerful storm hits Demba,’ reads the viral caption. Robin, a student thousands of miles away, feels a chill as he wonders if he knows her.”

It is a harrowing opening for The Carbon Paradox, a truly genre-defying work that blends fiction with fact to illuminate one of the most perplexing questions of our time: how do we fund climate action in an imperfect world?

book cover

The lead author, sustainability pioneer and Co-Founder of South Pole Renat Heuberger, explains that the book is not just about markets or policy frameworks. “First we put out the paradoxes surrounding carbon credits in detail,” Renat recalls. “But then we realised we had lived through all that. Would it be possible to make these credits come alive for people?”

Carbon credits are notoriously complex, riddled with acronyms and disputes. But in this fictional world, they are also deeply human. Behind every offset lies a forest, a community, a story, and sometimes, a tragedy.

“Our role is to build the platform, the framework,” he told me. “We can’t dictate the outcome, but we can cultivate the space for it. Think of it like a garden: we prepare the soil, provide the tools, and ensure access to water and sunlight. But it’s the people who must choose what to plant, and how to make it grow.”

That philosophy – humane, humble, and urgent – underpins the novel.

Why this book, why now

The timing, Heuberger admits, was not accidental. The project began as a technical mapping of what he and his collaborators call the carbon paradoxes — thirty dilemmas that have dogged the market since its inception. 

But real-world events quickly reshaped the fictional world. “When Trump became president again,” he said, “we realised that perhaps the end of the book was even more important. It couldn’t just be about credits and compliance. It had to be about people seeing and hearing each other again, meeting again, connecting.”

So the narrative took form: three university students, galvanised by a viral climate tragedy, set off for the tropics of Demba, a fictional tropical nation, to implement carbon-funded projects. Their journey becomes less about saving forests and more about navigating the various paradoxes that haunt every attempt at climate finance.

When policy becomes personal

One of the book’s vivid scenes takes place not in a government office or a corporate boardroom, but at a bar in Demba. Characters argue over whether oil companies buying credits is salvation or sham:

“Rower is extracting all that natural gas…They are among the main culprits responsible for accelerating climate change. Should the same group producing all this CO₂ buy our carbon credits, claiming to be clean and green?” Andy snaps. Ella shoots back: “Who causes all the CO₂ emissions? It is you, Andy. And me. All of us. We all depend on their oil! Who just flew to Demba? We did!”

It’s a fiery exchange — one that could just as easily unfold at Davos, or at any students’ debating club. . Robin, the more reflective member of the group, intervenes: “I’d call this the Polluters Paradox. On one hand, the biggest polluters should be buying carbon credits—they have the money, and they’re fueling the crisis. But on the other hand, they shouldn’t, because then it risks becoming greenwashing.”

In a few pages, Heuberger and his co-authors dramatise what climate lawyers, NGOs, and CEOs have debated for decades, and does so in a way that a general reader can feel, not just understand.

A novel of paradoxes

At its core, The Carbon Paradox humanises technical dilemmas. The paradoxes — voluntary vs. compliance markets, claims vs. impacts, polluters vs. pioneers — are not presented as academic puzzles. They unfold through characters who argue, dream, stumble, and grieve. “The characters came to life,” Heuberger said. “They had real emotions. They started to live their own life.”

This makes the book unusual in the literature of climate and finance. Where most accounts rely on white papers or polemic, Heuberger offers a hybrid: a fictional story grounded in documentary fact, with characters embodying the contradictions of global carbon markets.

Lessons beyond the page

The question, of course, is whether fiction can do what technical analysis often cannot: reach people outside the “carbon bubble.” Heuberger hopes so. “It’s easy to read. You don’t have to be a scientist to understand,” he said. The novel, he argues, models how climate communication might evolve — balancing rigor with story, numbers with emotions.

The experiment has already found resonance. In late 2024, Heuberger and his colleagues launched the paradoxes as a digital “Advent calendar,” releasing one each day in December. More than 3,000 users joined, commenting, critiquing, and sharing their own experiences. “It showed us that people are hungry to engage,” he said.

The central question

Can carbon credits, for all their flaws, still form a part of climate finance? The book doesn’t offer easy answers. In fact, it resists them. Instead, it insists that the way forward is collective. “If not all stakeholders come together, it doesn’t happen,” Heuberger told me. In the novel, it takes a professor to persuade NGOs, who persuade governments, who persuade business.

What do the authors hope readers will take away? Not a simple answer, but a habit of thought: root-cause reasoning, an openness to paradox, a recognition that no single stakeholder can solve the crisis alone.

The book ends not with triumph but with a question. Is there a future for carbon credits? Or are they doomed to remain symbols of an imperfect compromise?

“Once you’ve gone through all the options,” Heuberger reflects, “you come back to carbon credits — result-based finance tokens, or we could call them climate units. The question is, how do we rethink everything?”

In that sense, The Carbon Paradox is less a novel than a mirror: a reflection of the dilemmas we all live with, dramatised so that they cannot be ignored.
