Motivated by the rising consensus that corporate engagement in climate change actions holds the key for society's transition into environmentally resilient economy, the study examines whether a firm's commitment to climate change action and its carbon risk exposure shape the firm's debt financing policy. Based on insights drawn from signaling, corporate reputation, and agency theories, we develop models that link corporate commitment to climate change actions and a firm's carbon risk exposure with its debt financing decisions. Using data drawn from S&P 500 companies, for years 2015 to 2019, we find a robust evidence that firms that engage in higher levels of commitment to climate change actions issue a higher proportion of debt with longer terms to maturity, even after controlling for their carbon risk exposure. However, we do not find a robust evidence corroborating an association between firms' carbon risk exposure and their debt financing policy. These findings are consistent with arguments that high-commitment firms enjoy positive reputation, better credit rating, and reduced agency and information asymmetry costs, allowing them to gain easier access to long-term debt markets.climate change, corporate carbon commitment, corporate carbon risk, debt financing policies
| INTRODUCTIONCorporate debt financing policies and their interactions with agency and information asymmetry costs have received considerable attention in corporate finance and governance research. This is partly due to the importance of making optimal debt financing decisions in resolving agency problems (Myers, 1977), liquidity risks (Diamond, 1991), and information asymmetry and signaling challenges (Flannery, 1986). Notwithstanding the enormous role that corporate commitment to climate change actions could play in society's transition into low carbon and environmentally resilient economy (Bridge et al., 2020;Pinkse & Kolk, 2010;Richardson, 2009) and the observation that companies have begun considering climate change issues in their strategic positioning (Lee, 2012), no prior study has examined the interplay between a firm's commitment to climate change actions and its debt financing policy. This is a significant omission considering that corporate activities are widely deemed to be the primary drivers of climate change (Cadez et al., 2019;Dahlmann et al., 2019) and that a firm's climate change-related activities interact with its financing decisions (e.g., Jung et al., 2018;Lemma et al., 2019). The present study attempts to fill this void by investigating whether a firm's commitment to climate change actions shape its debt maturity structure.Corporate commitment to climate change actions comprises a gamut of a firm's climate change-related activities including the disclosure of its Greenhouse Gas (GHG) emissions; integration of its GHG emissions, strategies, and actions; benchmarking of its GHG emissions performance against industrywide performance; and the degree to which it demonstrates "climate leadership" by implementing best practices (B...
