Une étude menée sur 305 entreprises cotées en France, en Allemagne, au Royaume-Uni et au Japon, met en lumière l’influence du conseil d’administration sur la réduction des émissions de gaz à effet de serre (GES). Une empreinte surtout prégnante dans les entreprises les plus émettrices.

Do Corporate Governance Mechanisms Help to Reduce Carbon Emissions? Some Empirical Evidence on Listed Companies in France, Germany, the United Kingdom, and Japan

Financial regulation and innovative financingPublicationsPublicationsResearch areaResearch FellowsSandra RigotComments Off on Do Corporate Governance Mechanisms Help to Reduce Carbon Emissions? Some Empirical Evidence on Listed Companies in France, Germany, the United Kingdom, and Japan

 In this paper, we analyze the role of firms in mitigating climate change through their model of corporate governance. Our findings vary depending on the high- or low-emission sector. Based on these results, we propose several managerial and policy implications that can help improve corporate climate performance.

In situations of water shortage and unreliability of the public water supply service, the rehabilitation of old water supply systems could constitute an additional source of supply. The chapter questions both the rationale of their rehabilitation and the state of nowledge associated with their use, based on the example of the old city of Ahmedabad in India.

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

Albin KasserMaryam SadighiPublicationsResearch areaResearch FellowsSectoral PoliciesWorking papersComments Off on Development of Hydrogen Valleys: Defining a Merit-order of End-uses

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.

La finance à impact : éclairage sur les pratiques d’une société française de gestion d’actifs solidaires

Financial regulation and innovative financingPhilippe DevinPublicationsPublicationsResearch areaResearch FellowsComments Off on La finance à impact : éclairage sur les pratiques d’une société française de gestion d’actifs solidaires

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.

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

Maxence GérardPublicationsResearch areaResearch FellowsSectoral PoliciesWorking papersComments Off on Cattle diet and the carbon footprint of beef: a meta-analysis

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).
