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.

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...

Ecological policy mix: the SDSN France report

2025
Auteurs :
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...

Groundwater, climate change and conflict: Empirical Evidence from Africa

2024
Auteurs :
Mathieu Couttenier, Remi Jedwab, Lucile Laugerette

Groundwater plays a critical role in supporting economic activities in Africa, particularly in regions affected by climate change-induced water scarcity. This study examines the economic implications of groundwater in relation to conflict dynamics in these regions. The findings underscore the need for developing equitable water management strategies to mitigate conflict and promote sustainable
development...

What policy mix for the ecological transition?

2024
Auteurs :
Esther Jeffers, Dominique Plihon

This article looks at how to make fiscal, monetary and prudential policies greener in order to address the massive financing needs and major risks associated with climate change.

Starting with the observation, based on the recent experience of the financial and health crises, that the separate and independent implementation of monetary and fiscal policies undermines...

Long-term sustainability of zero-growth capitalism: activity, employment and unemployment according to different modes of income distribution

2025
Auteurs :
Laurent Cordonnier, Jacques Mazier

This paper studies the long-term consequences of a zero-growth regime on the evolution of employment and unemployment, depending on the assumptions we can make concerning the evolution of the working population, labor productivity and working hours. These consequences are examined through three scenarios. This leads us to conclude that the goal...
