The effect of greenhouse gas emissions on cost of debt: Evidence from Canadian firms

Abstract

AbstractThe aim of this paper is to investigate the relation between greenhouse gas (GHG) emissions and cost of debt and to estimate the cost that lenders are imputing to GHG emissions. Data on GHG emissions were hand‐collected from Carbon Disclosure Project reports, whereas data on the cost of debt and other financial data were obtained from Bloomberg Professional database. Using a sample of Canadian firms, the results show that GHG emissions increase firms' cost of debt. In other words, for each additional tonne of GHG emissions, the cost of debt increases on average by 11–15%. These results imply that creditors incorporate firms' GHG emissions into their lending decisions and they penalize the polluting firms. This could encourage firms to reduce and manage their GHG emissions because there is a cost associated with these emissions. This study is one of the first to examine the relationship between GHG emissions and the cost of debt.
