Abstract: This paper assesses to what extent markets with sophisticated investors and large firms price transition risks due to climate policies. The analysis exploits longitudinal data on firms’ economic and environmental performances - as measured by emission intensity, patenting activity in mitigation technologies, and ESG scores – and syndicated loan data. It provides three main results. First, firms with good environmental performance (in terms of emission intensity or patenting activity in mitigation technologies) benefit from a significantly lower cost of debt as climate-change mitigation policies become more stringent. Second, ESG scores and their environmental pillar are not sufficiently informative to assess and price domestic climate policy risks. Third, more stringent mitigation policies encourage investment in green firms by reducing the cost of debt: an increase of about EUR 10/t CO2 in carbon taxes raises investment by about 12% for firms with high patenting activity in mitigation technologies while it decreases investment by about 11% for firms with high emission intensity. The paper discusses policies to improve the available information on firms’ environmental performance metrics so as to enable investors who are smaller and less sophisticated than those participating in the syndicated-loan market to assess firms’ climate transition risks and to allocate capital in line with emission reduction targets.
