Invention and international diffusion of climate change mitigation technologies: an empirical approach

Abstract : This dissertation presents five empirical papers dealing with innovation activities in climate change mitigation technologies and their international diffusion. We first construct a data set including all patents filed worldwide since 1978 in 13 technologies with high climate change mitigation potential. We use this data to provide a descriptive analysis of innovative activity in these technologies and of their international diffusion. The data suggest that the Kyoto Protocol has induced more innovation in low carbon technologies. Both innovation and technology transfer are concentrated in developed countries, although exports to emerging economies are growing rapidly. We then use the same data to analyze the determinants of the cross-border diffusion of climate-friendly technology. We focus on the influence of various policy variables, including tariff rates, intellectual property rights and barriers to foreign direct investment. In the third paper, we focus on four renewable energy technologies and examine the influence of domestic and foreign regulation on innovation activity. We find strong evidence that inventors respond to foreign environmental regulation by increasing their innovation effort. In the second part, we build a data set of 644 projects registered under the Kyoto protocol's Clean Development Mechanism (CDM). We use this data to provide an assessment of the technology transfers that take place through the CDM and to analyze the drivers of technology transfer by CDM projects. In the last paper, we focus on four countries gathering about 75% of the CDM projects (Brazil, China, India and Mexico) and explain inter-country differences in transferring technology.
