Among them, four companies explicitly stated in their 2019 annual reports that "there are no major penalties or corrective actions" or "not applicable," which may constitute false statements. Six companies failed to disclose any environmental violations involving themselves or their subsidiaries or affiliated companies in their 2019 annual reports.
