What are the Drivers of Corporates’ climate transparency? Evidence from the S&P 1200 Index

2023
Auteurs :
Jeanne Amar, Samira Demaria et Sandra Rigot

Climate transparency through firms' disclosures is often considered a prerequisite for the redirection of investments toward low-carbon economy. In order to provide effective incentives to improve this transparency, it is therefore crucial to identify its drivers.

Mitigating greenhouse gas emissions from the cattle sector: land-use regulation as an alternative to emissions pricing

2023
Auteurs :
Maxence Gérard, Stéphane De Cara, Guy Meunier

The cattle sector, both emissions- and land-intensive, represents a great opportunity for mitigation through reforestation. In this paper, we study the efficiency of land-use regulation. Our analytical results indicate that the subsidy is the best alternative policy to emissions tax, provided that the elasticities of land use and emissions to cattle feeding are close. Interestingly,...

Do French firms follow a transparent or climate-friendly path?

2021
Auteurs :
Jeanne Amar, Samira Demaria, Sandra Rigot

Our analysis of the Climate Risks and Opportunities Index (CRORI) and the CDP climate score reveal a parallel improvement of these indices with different sectoral disparities over the 2015–2019 period. While our results are encouraging, they need to be put into perspective because these firms are still far from being carbon neutral.

EROI minimum et croissance économique

2023
Auteurs :
Victor Court et Florian Fizaine

Depuis quelques années, dans un contexte de raréfaction des hydrocarbures et de basculement vers les énergies décarbonées, plusieurs études ont essayé d’estimer l’impact d’une baisse de l’EROI sur le fonctionnement d’une société industrielle. Une autre façon d’approcher ce sujet revient à se demander s’il est possible d’estimer la valeur minimale d’EROI requise pour soutenir...

Mineral Resources and the Salience of Ethnic Identities

2023
Auteurs :
Nicolas Berman, Mathieu Couttenier, Victoire Girard

Our findings suggest a new dimension of the natural resource curse: the fragmentation of identities, between ethnic groups and nations.

The design flaw in Sustainability-Linked Bonds

2023
Auteurs :
Julien Lefournier

We examine in this paper sustainability-linked bonds (SLBs) whose issuance now totals more than USD 200 bn. There is a structural design flaw in the SLB mechanism: setting a significant coupon step-up does not suit the issuer’s nor the investors’ interests, considering conditionality. This creates a no win situation for the issuer and investors alike and explains the “benign”...

Essai sur l’accès à l’énergie et la concurrence des importations chinoises en Afrique

2022
Auteurs :
Quentin Hounyonou

Les pays africains aspirent à un développement industriel pour diversifier leurs exportations, actuellement concentrées en ressources naturelles. Cependant, l'électrification et le renforcement de la compétitivité des entreprises nationales restent un défi lorsqu'elles font face à la concurrence des importations, notamment celle chinoise.

Mettre en œuvre la transition énergétique ? Les enjeux de planification et de politique industrielle

2023
Auteurs :
Sous la direction de Jean-Pierre Ponssard

Cette note s’adresse à toute personne directement impliquée dans la mise en œuvre de la planification en vue d’atteindre les objectifs de neutralité carbone (NZE) fixés par la Stratégie Nationale Bas Carbone (SNBC).

Crop prices and deforestation in the tropics

2023
Auteurs :
Nicolas Berman, Mathieu Couttenier, Antoine Leblois, Raphael Soubeyran

Understanding the mechanisms of deforestation is necessary in order to slow or arrest its progress. To accomplish this requires rigorously estimating the demand for deforestation. We contribute to this endeavor by estimating the effect of crop prices on the demand for conversion of land from forest to agriculture in the tropics during the 21st...

Coordination of sectoral climate policies and life-cycle emissions

2023
Auteurs :
Quentin Hoarau and Guy Meunier

The present paper addresses the issue of sectoral policy coordination, especially when Pigovian carbon pricing is unavailable. It analyzes the optimal allocation of mitigation effort among two vertically connected sectors, an upstream (e.g. electricity) and a downstream (e.g. transportation) one.
