Using A-share listed companies from 2012 to 2022 as the sample, this study employs the difference-in-differences method to examine the impact of carbon emission trading policies on corporate ESG performance and its underlying mechanisms. The findings reveal that the carbon emission trading policy significantly improves the ESG performance of enterprises in pilot regions. This conclusion remains robust after a series of tests, including parallel trend estimation, placebo tests, changes in the sample period, and propensity score matching. Heterogeneity analysis indicates that the policy has a more pronounced effect on enhancing ESG performance for firms in high-energy-consumption regions and those with larger asset scales, with the most substantial improvement observed in the intersection group of these two categories. Mechanism tests show that the policy promotes ESG performance by encouraging enterprises to increase long-term asset investment, thereby driving technological upgrades and green transformation. Based on these findings, policy recommendations are proposed, including improving the carbon market system, innovating carbon financial products, integrating carbon management into corporate ESG strategies, and strengthening financial incentive mechanisms.
