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 allocation.
Plug-in hybrid electric vehicles (PHEVs) occupy a particular position in European CO2 regulation. Their certified emissions depend on a regulatory Utility Factor, which determines the assumed share of driving performed in electric mode. Evidence from real-world driving has shown that this share was substantially overestimated, leading European regulators to revise the UF from 2025 onward. This reform changes the compliance role of PHEV for car manufacturers facing the EU emission standards. This paper quantifies the market, environmental and welfare consequences of this reform.
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?
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 égard : d’une part, la concurrence qui y est notoirement imparfaite, et d’autre part, l’adoption des technologies de capture et de séquestration du carbone (CSC) constitue une étape indispensable pour éliminer les émissions incompressibles liées au processus de production.
This study explores to what extent the implementation of managerial Climate Management Practices (CMP) adopted by large publicly traded firms is associated with Corporate Financial Performance (CFP), measured by Tobin’s Q. The results show that most CMP are not significantly linked to Tobin’s Q, implying that markets largely view them as neutral with respect to value creation. These findings offer practical insights for managers, investors, and regulators, highlighting how climate management practices can be structured to better align with evolving market expectations.
This study investigates the relationship between distinct types of inequality and CO2 emissions using panel data on 156 countries from 1995 to 2020. These findings call for international cooperation and public policies aimed at a more equitable primary income distribution to achieve joint inequality and reduction of carbon emissions.
This book offers a comprehensive exploration of how empirical stock-flow consistent (SFC) modelling can be used as a tool for macroeconomic analysis.
Autonomie et recharge, recyclage, dépendance à la Chine, impacts environnementaux et sociaux, durée de vie, prix… les véhicules électriques et en particulier leurs batteries soulèvent de nombreuses questions, avec parfois leur lot d’idées reçues et de désinformation. L’article vise à décrypter ces questions en 12 points clés.
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 of total emissions.
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: urea. To address this knowledge gap, our study employs a Vector Error Correction Model using global monthly data from 1985 to 2023.
