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 with an increasing Social Cost of Carbon (SCC). When the SCC surpasses a threshold defined by the Social Opportunity Cost of Abatement (SOCA), allocating hydrogen to the most emissions-intensive sector becomes socially optimal, even if that sector has a higher sectoral abatement cost.
On February 7, we hosted the 11th International Conference on Mobility Challenges, where we engaged with leading academics, stakeholders from the automotive industry, civil...

Cet article propose une analyse comparative d’un fonds solidaire « 90-10 » recherchant principalement la performance financière (fonds « A ») et d’un fonds solidaire spécialisé (fonds « B »), privilégiant la création d’impacts positifs sans performance financière. Ces fonds combinent les notions d’impact et de solidarité de manière hybride : communication d’une part, pratiques de financement et de sélection d’autre part.
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).
La transparence : une condition nécessaire à la réorientation des investissements vers une économie bas carbone, mais pas suffisante. Quels sont les déterminants qui influencent la transparence climatique des firmes européennes ?
Conflits d'intérêts et capture des régulateurs soulèvent des questions éthiques majeures susceptibles de saper la légitimité de l'action publique. Cet article défend l'idée que les cours d'éthique dans l'enseignement supérieur peuvent être structurés de sorte de lieux armer les futurs décideurs privés et publics face à ces problématiques.
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.
This article explores the critical role of energy in shaping capitalist modes of development, and their entry into crisis, in France between 1960 and 2020. This analysis challenges traditional views that regard energy primarily as an exogenous shock and instead posits energy as a fundamental metabolic constraint in capitalist accumulation regimes and proves that neoliberalism's structural crisis is rooted in the exhaustion of past energy management strategies, opening the door to the emergence of post-liberal capitalism.
Herein we study carbon taxation considering the structure of the global production network. With this purpose we characterize how the implementation of a carbon tax in one country-sector can generate sizeable fluctuations on global emissions and welfare through its impact on the structure of production.
