The diffusion of technologies emitting less Green House Gases (GHG) in developing countries should play a key role in mitigation to climate change. Accordingly, this is a key issue in the on-going discussion on the Post-Kyoto regime. In this program, we develop quantitative analyses, case studies, and theoretical models to assess the importance of technology transfer and explore policy solutions that could facilitate the international diffusion of inventions.

The research team involves Antoine Dechezleprêtre, Matthieu Glachant and Yann Ménière. We also cooperate with Nick Johnstone and Ivan Hascic from the Empirical Policy Analysis Unit, OECD Environment Directorate.

Beyond patents: innovation, competition and technology diffusion in the photovoltaic industry

Invention and Transfer of Climate Change Mitigation Technologies on a Global Scale: A Study Drawing on Patent Data

NEW !!! A revised version of the report is here.

This work has been financed by AFD and carried out by Cerna in cooperation with Nick Johnstone and Ivan Hascic from OECD. It provides an in-depth analysis of the geographic distribution of 13 classes of climate mitigation inventions since 1978 and their international diffusion on a global scale. To the best of our knowledge, this is the first quantitative work with this comprehensive geographical scope.

Technology Transfer and the Clean Development Mechanism

Recently published works and working papers on the Clean Development Mechanism include:

• Matthieu Glachant and Yann Ménière (2006) "Economie industrielle des MDP/MOC: les cas de Pannonpower et Indocement", report for the French environmental agency ADEME. This report presents two case studies of CDM/JI projects in Hungary and Indonesia (in French).
• Antoine Dechezleprêtre, Matthieu Glachant and Yann Ménière (2008) "The Clean Development Mechanism and the international diffusion of technologies: an empirical study", 36(4), Energy Policy, pp 1273-1283. This paper exploits a database of 644 CDM projects. It yields descriptive statistics on technology transfers in these projects. We also develop econometric regressions to identify the underlying drivers.
• Antoine Dechezleprêtre, Matthieu Glachant and Yann Ménière (2008) "Technology transfer by CDM projects: A comparison of Brazil, China, India and Mexico" Energy Policy, 37(2), pp 703-711. This is a companion paper of the previous one which use the same data and models to compare Brazil, China, India and Mexico.
• Matthieu Glachant and Yann Ménière (2008) "Kyoto Project Mechanisms and Technology Diffusion", working paper. We develop a theoretical model to analyze key properties of technology diffusion processes in CDM projects. We also derive policy implications for the design of international emissions trading schemes.
  

We are currently writing new papers. We will keep you informed.
