Send us a text Air pollution isn’t just a climate co-benefit—it’s the number one threat to human health. In this best-of compilation, we revisit three standout conversations to trace the arc from global impacts to two of the world’s most important case studies: China and India. Both tackled air pollution, but one In this episode: The global picture (Dr. Christa Hasenkopf, EPIC – UChicago): Why fine particulate matter (PM2.5) quietly shaves ~2 years off global life expectancy—and how mic...

Send us a text Marion Kruger, co-founder of Remove, explains how carbon removal technologies are essential for achieving net zero targets by compensating for emissions that are impossible or extremely expensive to eliminate. Carbon removal is what puts the "net" in net zero, and by 2050, we'll need to remove 5-10 gigatons of CO2 annually—creating an industry comparable in size to today's oil and gas sector. • Three main types of carbon removal technologies: nature-based, hybrid, and engineer...

Send us a text Did the 2018 US–China trade war make China’s air dirtier and increase its CO2 emissions? This question is not easy ex-ante. On the one hand you have a decrease in production which decreases emissions and pollution. On the other hand, there is more pressure on politicians to relax environmental standards. Notice any similarities with recent events? In my latest episode, I therefore sit down with Prof. Lorenzo Trimarchi to unpack these forces in his new JDE paper, “Th...

Send us a text Find the clean transcripts on my Substack: https://substack.com/@climateeconomicswitharvid Could market forces be the key to solving one of the world's most pressing public health crises? The evidence from India's groundbreaking air pollution markets suggests a resounding yes. Air pollution in India has reached catastrophic levels. With 74 of the world's 100 most polluted cities located there, the average Indian loses 3.5 years of life expectancy to dirty air. In Delhi, that n...

Pricing carbon is the backbone of climate cost-benefit analysis in the U.S. If the price is high, stronger environmental rules pay for themselves; if it’s low, they don’t. In this episode, I trace how the social cost of carbon entered federal policy and why the number has shifted between administrations. What we cover From Reagan-era cost-benefit rules to a 2007 court case that rejected “carbon = $0”The Obama team’s Interagency Working Group and a unified SCC built from leading IAMsTrump’s sh...

A plain-English tour of how economists put a price on climate harm—the Social Cost of Carbon—and a quick way to estimate damages with just a few numbers. We start from 2023 anchors (≈4.7 tCO₂ per person; ≈38 GtCO₂ worldwide), explain SCC and how U.S. administrations have used very different values, and compare with recent EU carbon-permit prices. Using a €100/ton example, we translate emissions into ~€500 per person per year and ~3.8% of global GDP, then show how the result scales...

Carbon credit offsets sound great in theory. But how well do they actually work in practice? In this new episode of my podcast, I talk with Dr. Benedict Probst about one of the largest reviews ever done on the effectiveness of carbon credit offsets, which covers over 1 billion credits across dozens of studies. We discuss what his research says, why less than 16% of credits were found to be effective, and what this means for future climate policy, especially as the EU considers offsets in its ...

Air pollution is responsible for shortening global life expectancy by more than two years—making it the world’s leading threat to human health, ahead of HIV/AIDS, malaria, and even smoking. Yet it receives only a fraction of the funding and policy attention. In this episode, Dr. Christa Hasenkopf breaks down why air pollution is such a silent but devastating force—especially in the Global South—and what can be done to fight it. From real-time data sharing in Mongolia to clean air markets in I...

In this episode, I speak with Dr. Ishan Nath, assistant professor at the Harvard Kennedy School, about his research on climate change, agriculture, and trade. His forthcoming paper in the Journal of Political Economy explores how warming could actually increase the share of workers in agriculture in many low-income countries, especially those with limited access to trade. We discuss why trade barriers matter for climate adaptation, what makes agricultural labor patterns persistent, and how ec...

In this episode, I sit down with Dr. Koen Deconinck, economist and policy analyst at the OECD, to explore a deeply technical but increasingly important piece of the climate puzzle: how we measure greenhouse gas emissions in the agricultural sector. Direct and indirect emissions in Agriculture are responsible for up to 30% of global man-made emissions, yet it's often left out of the climate conversation. Why? Because measuring these emissions accurately is really hard. Dr. Deconinck walks us t...
