The deforestation effect of climate aid

2025
Auteurs :
Bertille Daran, Clément Nedoncelle

This study examines the impact of climate aid on deforestation in Africa from 2001 to 2021, using a novel dataset of geocoded aid projects. The effects are heterogeneous and vary by initial forest cover: aid increases deforestation in densely forested areas, while it appears to reduce deforestation where forest cover was initially sparse. 

The Cultural Roots of Deforestation in Africa

2025
Auteurs :
Mathieu Couttenier, Raphael Soubeyran, Nicolas Berman

We study the relationship between culture and environmental conservation through the lens of deforestation. Focusing on Sub-Saharan Africa over the period 2001-2021, we show that changes of national leaders affect deforestation in a way that depends on the environmental culture of their ethnic group’s. Our results suggest that culture is an important lever for environmental conservation...

This article  analyses the role that central banks could play in dealing with stranded "brown"assets as a result of the ecological transition.The estimates provided thtough a database that we are building for the analyses suggest that central banks, as "liquidators of last resort" of stranded asset markets, would inject volumes of liquidity comparable to...

Imperfect Competition and the Adoption of Clean Technology: The Case of CCS in Cement

2025
Auteurs :
Quentin Hoarau, Jean-Pierre Ponssard

his paper studies the adoption of clean technology in an oligopolistic setting, focusing on carbon capture and storage (CCS) in the cement sector. Firms can choose between two technologies: a carbon-
intensive ("dirty") technology and a low-carbon ("clean") one.

Greening the car fleet: demand characteristics, policy impacts and new product introduction

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...
