Prioritising Renewable Hydrogen End-Uses: A Merit-Order Framework

2026
Auteurs :
Maryam Sadighi, Albin Kasser

Renewable hydrogen remains costly and its availability is constrained. Only 10% of planned global clean hydrogen capacity for 2030 has identified buyers. This raises the question of which end-use sectors should be prioritised as deployment progresses.The paper examines how learning subsidies, targeted demand-side support and production incentives linked to end-use commitments can improve hydrogen...

Technology Neutrality vs. Policy Discrimination: Optimal Policy Design for Competing Green Technologies

2026
Auteurs :
Albin Kasser, Guy Meunier

The deployment of clean technologies in hard-to-abate sectors is often hindered by high costs and investment risks. Carbon Contracts for Difference (CCfDs) have emerged to mitigate these risks, yet their design raises a central question: should support for competing clean technologies be technology-neutral or technology-specific?

Quels sont les enjeux concurrentiels associés à la décarbonation des sites industriels ?

2026
Auteurs :
Christophe Caron, Jean-Pierre Ponssard

Cette note s’intéresse à l’articulation des méthodologies d’évaluation de projets lorsqu’on passe du point de vue public au point de vue privé. Il s’agit plus particulièrement d’analyser comment les enjeux concurrentiels dans les décisions d’investissement de rupture pour la décarbonation des sites industriels influent sur cette articulation. Le secteur cimentier est emblématique à cet...

When Green Policies Backfire: Deforestation and Sri Lanka’s Fertilizer Ban

2026
Auteurs :
Lauren Ouedraogo, Raphael Soubeyran,

Economic regulations often generate unintended consequences beyond their intended scope. We exploit Sri Lanka's abrupt 2021 nationwide ban on chemical fertilizer imports as a quasi-natural experiment to identify how hard input constraints reshape land-use decisions. 

Wealth Inequality Reduction as a Climate Change Policy? Evidence on Political Channels

2026
Auteurs :
Tobias Angel

Using a two-stage least squares estimator for a panel of 165 countries from 2000 to 2023, the paper shows that lower wealth inequality decreases land use change emissions. The effect is most pronounced when inequality is measured by the top 10% wealth share and in developing countries, where land use change emissions constitute the majority...

Disentangling what Drives Global Urea Price: Short-Run and Long-Run Effects

2026
Auteurs :
Emma Skalski, Marilyne Huchet, Marie-Hélène Hubert

The concurrent surge in fuel, food, and fertilizer prices underscores the broad vulnerability of agrifood system in an interconnected global economy, where supply chain disruptions can propagate rapidly. It also highlights the urgent need for a deeper understanding of the short-and long-term drivers of the price of the world's most widely used nitrogen fertilizer:...

Public Banks and the Ecological Transition: Towards a Paradigm Shift in European Financial Policy

2026
Auteurs :
Sandra Rigot, Dominique Plihon, Robert Guttmann

Since 2015 the European Union has positioned itself as global leader in the ecological transition, placing the goal of carbon neutrality by 2050 at the heart of its economic and financial agenda. This article examines the role of public banks, particularly the European Investment Bank (EIB), in structuring the financing of the green transition.

Subsidising Electric Cooking to Protect the Environment: Evidence from a Randomized Trial in the D.R. Congo

Sébastien Desbureaux, Lara Collart, Nik Stoop, Raphael Soubeyran, Marijke Verpoorten, Mathieu Couttenier, Christine Cikesa, Jean de la Croix Kembere Mulwahili,Natsuno Shinagawa

This randomized controlled trial investigates how to accelerate the transition to the cleanest cooking fuel, electricity, and quantifies the benefits for people and the environment. 

Historical Carbon Debts and Credits – 1750-2023

2025
Auteurs :
Tobias Angel, Alain Naef

Historical contributions of carbon emissions differ widely between nations, constraining climate change negotiations. Cumulative country estimates ignore historical populations, overstating the role of large-population countries. In this paper, we present a global accounting framework. Adding CO2 emissions from land use change radically reshapes the map, moving Brazil from the world’s 8th largest creditor to...
