Development of Hydrogen Valleys: Defining a Merit-order of End-uses

2025
Auteurs :
Albin Kasser, Maryam Sadighi

Hydrogen valleys, which integrate renewable energy sources, hydrogen infrastructure, and end-use applications, play a crucial role in decarbonizing industrial energy hubs. However, the large-scale deployment of hydrogen is constrained by limited renewable electricity availability and high technology costs. A key insight from our analysis is that the merit order of hydrogen end-uses is dynamic, evolving...

Cattle diet and the carbon footprint of beef: a meta-analysis

2025
Auteurs :
Maxence Gérard

Grass-based beef cattle production systems are generally perceived as beneficial to the environment. However, the climate impact of grass-based systems compared to systems based on energy-dense feeds remains controversial. The findings highlight potential trade-offs between climate goals and other sustainability objectives (e.g., biodiversity, animal welfare).

Evaluating second-hand EVs subsidies Efficiency and Welfare Gains

2025
Auteurs :
Ariane Bousquet, Juan-Pablo Montero, Maria-Eugenia Sanin

The recent inclusion of second-hand EV subsidies in several countries raises questions about their economic rationale. Contrary to conventional thinking, we show that while subsidies for second-hand EVs are often justified on equity grounds, they also improve efficiency as they influence the equilibrium composition of the vehicle fleet.

Some don’t like it hot: NGO campaigns and the market valuation of « dirty » banks

2025
Auteurs :
Thierry Mayer, Jean-Stéphane Mésonnier and Clément Mazet-Sonhilac

We exploit new data on NGO campaigns that target banks financing fossil fuels ("brown'' banks) to build a measure of French banks' environmental reputation, which we merge with granular data on bank deposits and loans of households in France over 2010-2020. We find that banks receive relatively fewer household deposits when they are perceived...

Warning words in a warming world: central bank communication and climate change

2025
Auteurs :
Emanuele Campiglio, Jérôme Deyris, Davide Romelli, Ginevra Scalisi

This paper studies climate-related central bank communication using a novel dataset containing 35,487 speeches delivered by 131 central banks from 1986 to 2023. It employs natural language processing techniques to identify and trace the evolution of key climate-related narratives centred around (i) green finance, and (ii) climate-related financial risks. Equity returns of "green" firms outperform those of "dirty" firms...

Mission Accomplished? A Post-Assessment of EU ETS Impact on Power Sector Emissions

2024
Auteurs :
Mohammadehsan Eslah, Anna Creti, María-Eugenia Sanin

This paper leverages a new method in the construction of credible counterfactuals for causal inference. This paper adopts a Bayesian structural time series (BSTS) modeling framework alongside a set of contemporaneous predictors related to power sector emissions to build counterfactual estimates of emissions for each post-intervention period and analyze the policy implementation effect by...

Energy Poverty has a justice dimension: comparing Bolivia, Côte d’Ivoire, and France

2024
Auteurs :
Anna Creti, Alpha Ly et Maria-Eugenia Sanin.

Energy poverty is a multidimensional issue, as demonstrated by a comparison between two low-income countries, Bolivia (BOL) and Côte d’Ivoire (CIV), and a high-income European country, France (FRA). These three countries represent different stages of access and energy poverty. The findings highlight the importance of considering affordability in efforts to ensure universal energy access, to...

Aubert, N., Couppey-Soubeyran, J., Didier, R., Dufrêne, N., Hollandts, X., Lagoarde-Ségot, 1 T., Le Quang, G., Le Poder, L., Massa, I., Mathieu, A., Peters, A., Ponsot, J.F., Revelli, C., Scialom, L., Sersiron, A., Toure, S., Van Weeren, M.

The report attempts to respond to the UN Secretary-General's recent call for "innovative approaches and bold policy decisions" to tackle the SDGs (UN, 2023). It attributes the existing finance gap to the unrealistic assumptions of the dominant macroeconomic paradigm, which it proposes to replace with new assumptions that are better able to address the...
