New publication: Designing Carbon Pricing Policies Across the Globe with Robert Schmidt and @moritzdrupp.bsky.social in Environmental and Resource Economics!

We present the largest international expert survey on carbon pricing design (400+ participants, ~40 countries). Some highlights.

Conclusion:
Tackling climate change & inequality requires an integrated perspective. Neither challenge can be fully understood in isolation—nor can policy succeed if it ignores their interdependence. We close with thoughts on a roadmap for future research at the inequality-environment nexus.

3️⃣ Redistribution (e.g. carbon dividends) can overturn potentially regressice policy costs, but has an ambiguous effect on environmental outcoems.

Moritz Drupp @moritzdrupp.bsky.social · Sep 1

What does the evidence to date say?
1️⃣ Environmental benefits (like cleaner air) are often distributed pro-poor.
2️⃣ Policy costs (like carbon taxes) can be regressive—but context and design matters.

Moritz Drupp @moritzdrupp.bsky.social · Sep 1

We highlight three key channels linking inequality and the environment:
1️⃣ How environmental benefits vary with income
2️⃣ How policy costs are distributed across households
3️⃣ How inequality and redistribution shape environmental outcomes

Summary:
Environmental degradation and economic inequality are two defining challenges of the 21st century. In this article, we synthesize how they interact—and why reseacher and policymakers should not treat them in isolation.

Germany's eco-tax reform led to sizable reductions not only in carbon emissions but also in harmful local air pollutants. Benefits accrued disproportionately to lower-income and more polluted areas.

Graph showing the evolution of transport fuel taxes in Germany and OECD average.

Fuel and carbon prices are typically assessed based on their effectiveness in reducing emissions, while their broader societal benefits often go overlooked. This column evaluates one of the world’s largest environmental tax experiments – Germany’s eco-tax reform – and finds that it led to sizable reductions not only in carbon emissions but also in harmful local air pollutants. Estimates reveal that two-thirds of the monetised benefits of the eco-tax stemmed from health gains linked to cleaner air and accrued disproportionately to lower-income and more polluted areas, suggesting that fuel taxes can deliver pro-poor environmental gains, even when their cost incidence is regressive.

Check out this great paper by @felixschaumann.bsky.social with @edualastrue.bsky.social out now in @pnas.org that integrates climate science with climate economics to study the social cost of carbon implications of reduced AMOC weakening. Super impressive work for a first PhD chapter👇

Felix Schaumann @felixschaumann.bsky.social · Feb 25

🚨 First PhD paper in @pnas.org 🥳

🌊 @edualastrue.bsky.social and I looked at how much less CO2 will be taken up by the ocean if the #AMOC weakens - and how this reduced ocean carbon uptake affects the social cost of CO2 emissions.

Don’t have a particular insight into the ruling, but the product has protected my head very well when I got hit by a truck on the bike, so it’s very sad to see this discontinued.

I'd say there is a strong case to be made that more philosophising is needed in SCC-work. @paulkelleher.net, we had a structural extension category "Alternative Ethical Approaches", which didn't make it into our featured categories due to low N & is also rarely coupled with other extensions (Fig S4)

Moritz Drupp @moritzdrupp.bsky.social · Dec 18

😅 this was also the most difficult survey yet to answer that I've sent out - but I had a hunch that you'd enjoy some of the qualitative comments 😀 I think a combination of what determines what we call the "SCC wedge" plus qual-comments is a useful indication for where SCC research may be headed

Check out this thread by @climatefran.bsky.social on our new paper in @pnas.org out today providing most comprehensive (i.e. still incomplete) evidence on the social cost of CO2 (SCC), with a meta-analysis + expert survey & a combination of elements of both to generate a “synthetic SCC” (mean≈$280)👇

Excited to announce a new @pnas.org publication on the Social Cost of Carbon. We integrate evidence from the literature and expert survey to provide an SCC distribution inclusive of both parametric and structural uncertainties. Our mean 2020 value is $283 per ton CO2

With our teaching, we seek to stir students’ enthusiasm for the possibilities in which economic theories & empirical methods can help to better understand and manage sustainability challenges. We furthermore actively contribute to the societal debate & help to improve public policy.

We publish our work in general economics journals (e.g. AEJ: Policy, JEL @aeajournals.bsky.social), field journals (e.g. JEEM @jeem-econ.bsky.social), & interdisciplinary journals (e.g. PNAS @pnas.org, Science @science.org).
