Effects of Greenhouse Gas Emissions and Climate Change Policy on Audit Fees

ABSTRACT This study explores the correlation between greenhouse gas (GHG) emissions from U.S. companies and their audit fees, driven by the escalating frequency and intensity of extreme weather events. Building on prior research that connects climate risk, regulation, and audit fees, our investigation uses a sample of companies with Scope 1 GHG emissions sourced from the U.S. Environmental Protection Agency’s (EPA’s) Greenhouse Gas Reporting Program (GHGRP). Our results show a positive association between GHG emissions and audit fees. Additionally, we find that regulatory uncertainty surrounding U.S. climate policy intensifies this relationship. Our findings are robust to alternate model and variable specifications. This research benefits managers and policymakers by highlighting some of the financial consequences of corporate GHG emissions, especially when combined with inconsistent climate policies. It is also beneficial to accountants in practice or researchers interested in refining their audit fee models. Data Availability: Data are available from the sources cited in the text.
