The effect of uncertainty related to environmental damages or technological change has on the optimal level of environmental policy stringency has been extensively analysed in the literature. However, empirical evidence on the innovation efforts of firms in the face of actual policy uncertainty...

This paper uses patent data to assess policy factors (domestic and international) for patenting activity in automotive emission control technologies. Particular attention is paid to the role of different policy types and fuel prices on both post-combustion and integrated abatement technologies....

This paper uses the EPO/OECD World Patent Statistical Database (PATSTAT) to provide a quantitative description of the geographic distribution of inventions in thirteen climate mitigation technologies since 1978 and their international diffusion on a global scale. Statistics suggest that...

This article examines the effect of the Kyoto Protocol's Clean Development Mechanism (CDM) on the international transfer of wind power technologies. The analysis is conducted using patent data from over 100 countries during the period 1988–2008. It is found that transfers from Annex I...

It has long been argued that the implementation of market-based environmental policy instruments such as environmentally-related taxes and tradable permits is likely to lead to greater technological innovation than more direct forms of regulation such as technology-based standards. One of the...
