This study proposes a new indicator of Climate Policy Uncertainty based on newspaper coverage frequency. The indicator currently includes 12 OECD Member Countries and covers the period 1990-2018. The index spikes near major political events and during major discussions around potentially...

Despite decades of global attention, effective climate policy implementation remains challenging, with firms and investors often grappling with uncertainty about potential policymaking in addition to actual policy changes. This paper introduces a novel Climate Policy Uncertainty (CPU) index,...

The European Union Emissions Trading Scheme (EU ETS) has aimed to encourage the development of low-carbon technologies by putting a price on carbon emissions. Using a newly constructed data set that links 8.5 million European companies with their patenting history and their regulatory status...

Using patent data from 66 countries for the period 1990–2003, we characterize the factors which promote or hinder the international diffusion of climate-friendly technologies on a global scale. Regression results show that technology-specific capabilities of the recipient countries are...

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...

The Clean Development Mechanism (CDM) is expected to stimulate the North-South transfer of climate-friendly technologies. This paper provides an assessment of the technology transfers that take place through the CDM using a data set of 644 registered projects. It provides a detailed description...
