This is the online appendix to the paper “How should we measure environmental policy stringency? A new approach” (Sauter, 2014). The main paper outlines the general methodology proposed to construct environmental policy indexes and proposes a first implementation of a CO2 input index and a CO2 performance index. This online appendix reports the results of the implementation of a SO2 input index, a SO2 performance index, a CH4 input index, a CH4 performance index as well as the broad GHG input index. All of those indexes have been constructed using the methodology outlined in the main paper.
