Abstract

In June 2023, the International Financial Reporting Standards Foundation (IFRS Foundation) released the International Sustainability Standards Board (ISSB)Standards, which established a unified and updated global framework for sustainability reporting, thereby ushering in an era of standardized sustainability information disclosure globally. So far, more than 20 countries, including China, have announced the adoption or reference of the ISSB standards, among which the new standards have exerted a significant impact on the subsequent development of traditional fuel vehicle companies. This study employing Mercedes-Benz as a case company, based on the Mercedes-Benz market return rate data and the German DAX30 market return rate data on the Investing.com website, and application of the short-term event study methodology and univariate linear regression analysis to comprehensively analyze the impact of changes in sustainable information disclosure standards on the traditional fuel vehicle industry. The study found that changes in sustainable disclosure policies have heightened the sensitivity of Mercedes-Benz’s stock price, and policies have compelled corporate transformation. Mercedes-Benz’s active adoption of the International Sustainability Standards Board (ISSB) standards has fostered positive investors expectations for the company’s long-term competitiveness under the new standards.
