Environmental reporting can help firms stay in compliance with environmental regulations and manage environmental risks. By proactively addressing and disclosing their environmental impact, manufacturing firms can mitigate potential legal and regulatory penalties, fines, and reputation damage, thereby safeguarding their financial performance. In addition to the latter perspective, cost savings and operational efficiency, enhanced reputation and stakeholder engagement, as well as access to capital and investment opportunities, are critical factors to ensure that firms disclose information about their environmental performance, including its impact on the environment, sustainability initiatives, and environmental risks and opportunities to ensure that they maximise their financial performance. Hence, the aim of this study is to explore the relationship between environmental reporting and financial performance of South African listed manufacturing firms. A multiple regression analysis was adopted to achieve the aim by testing the relationship between the variables amongst a sample of 50 manufacturing firms listed on the Johannesburg Stock Exchange (JSE). A content analysis was utilized to attain environmental reporting information themes from the integrated annual reports retrieved from the JSE for the period 2016 to 2020. The results indicate a negative association between environmental reporting responsibility and financial performance, measured by return on equity (ROE) when the components of environmental reporting are tested individually. However, when these components namely: environmental reporting, social reporting and environmental degradation are combined the findings reveal a positive and statistically significant relationship. These results imply that the adoption of environmental reporting, specifically an increase on the quality of environmental reporting results in an increase in the manufacturing firm performance.
