This paper investigates how firms’ pollution incentives are influenced by their ability to divest polluted assets. My empirical setting is a major reform that exempts purchasers from liability for past contamination. Using a difference-in-differences framework, I find that the reform reduces toxic emissions, lowers bankruptcy risk, and increases firm value. Cross-sectional tests show that the decline in emissions is driven by firms with weaker financial health and fewer assets. These findings highlight a novel net worth channel: by limiting ex-post liability, the reform enhances landowners’ net worth ex-ante, reducing their incentives to engage in risky behavior, such as excessive emissions.
