The episode connects rising premiums to broader economic impact...

When a mid-sized company moves its data to the cloud, the carbon footprint can rival a transatlantic flight. This episode examines a real migration by a European retailer that shifted 200 servers to AWS in 2025. We track the embedded carbon of new hardware, the energy mix of the data center region, and the often-ignored 'rebound effect' where cloud efficiency leads to more data storage, not less....

Episode 25 of Climate Economics with Fexingo: Lucas and Luna tackle the overlooked power of methane regulation. While carbon dioxide dominates headlines, methane packs 80 times the warming punch over 20 years. They walk through the EPA's new methane fee that went into effect in late 2025 — a $900 per ton charge on excess emissions from oil and gas facilities. Lucas explains why the fee is designed...

Steel production accounts for roughly 7 percent of global carbon dioxide emissions. In this episode, Lucas and Luna examine the emerging economics of green steel — made with hydrogen instead of coal. They break down the cost premium green steel carries today, why major automakers like Volvo and BMW are already signing supply deals, and what it would take for green steel to reach price parity with...

Saudi Arabia has announced plans to invest over $100 billion in renewable energy and green hydrogen by 2030, even as it remains the world's largest oil exporter. This episode examines the economics behind the Kingdom's dual strategy: maintaining oil revenue while building a post-carbon future. We look at the specific numbers: the $500 billion Neom megacity project, the $8.4 billion Green Hydrogen...

Lucas and Luna trace the carbon footprint of a single cup of coffee from farm to landfill, revealing that the biggest emissions are not where you think — and that the average American coffee habit adds roughly 200 kilograms of CO₂ equivalent per year. They break down the surprising role of refrigeration, the methane from spent grounds, and why switching to oat milk isn't the silver bullet marketer...

Episode 21 of Climate Economics with Fexingo. Lucas and Luna dive into the quiet revolution in institutional investing: how pension funds and endowments are being forced to price climate risk into their portfolios—not because they want to save the planet, but because the math now demands it. Lucas unpacks the story of the California Public Employees' Retirement System, CalPERS, which lost an estim...

This episode dives into the overlooked carbon footprint of concrete, the second most consumed substance on Earth after water. Lucas and Luna unpack how cement production alone accounts for roughly 8 percent of global carbon dioxide emissions — more than aviation and shipping combined. They explore emerging alternatives, from carbon-cured concrete to synthetic limestone, and ask whether the constru...

Office buildings account for nearly 40% of global carbon emissions, yet most investors ignore the operational vs. embodied carbon distinction. This episode drills into the specific case of 1 Embarcadero Center in San Francisco — a 45-story tower built in 1971 that underwent a $100 million retrofit to meet net-zero standards. Lucas and Luna unpack why retrofitting existing buildings is often cheape...

Episode 17 of Climate Economics with Fexingo digs into the quiet, multi-billion-dollar subsidy baked into every electric vehicle sold in America: the federal tax credit. Lucas and Luna explore why automakers like Tesla and General Motors have already hit the 200,000-vehicle cap, while Ford and Rivian still benefit. They break down the Treasury's complex battery sourcing rules unveiled in May 2024,...

Episode 16 of Climate Economics with Fexingo takes stock of the Inflation Reduction Act one year after its passage. Lucas and Luna drill into one specific outcome: the surge in domestic clean-tech manufacturing versus the slow rollout of direct consumer rebates. They examine why the law's 45Q carbon capture tax credit has barely moved the needle on CCS deployment, while the Advanced Manufacturing...

Tree planting is one of the most popular climate solutions, but the economics are surprisingly fragile. In this episode, Lucas and Luna break down the real cost per tree—from seedling to survival—using data from the World Economic Forum and recent corporate pledges. They explore why many tree-planting projects fail within five years, how carbon prices affect viability, and what it actually takes t...

Every year, billions of dollars worth of returned goods end up in landfills or incinerators, creating a massive carbon footprint that most consumers never see. In this episode, Lucas and Luna dig into the logistics of reverse supply chains, the economics of why it's often cheaper to destroy a returned item than resell it, and what companies like Patagonia and IKEA are doing differently. They also...

Lucas and Luna dig into the single most underappreciated obstacle in climate economics: permitting reform. With a new bipartisan bill in the US Congress in May 2026 aiming to speed up environmental reviews for clean energy projects, they explore why a typical solar farm can take 7 years to get through federal permitting, how that affects project costs and returns, and what the proposed 2-year fast...

Lucas and Luna unpack the European Union's Carbon Border Adjustment Mechanism (CBAM), the world's first carbon tariff, which took full effect in April 2026.
