Mining firms are used in this study, given the nature of their operations. Most studies on waste management have focused on the mandatory waste management practices rather than those that are voluntary. Statutory requirements have ensured full compliance with legislation. The advent of the JSE SRI has played a significant role in promoting environmental consciousness among firms. As such, the paper explores existing literature and company documents and analyzes the waste management practices of the selected firms, both mandatory and voluntary, based on the firms’ market share by revenue. International frameworks, guidelines and standards are used as a yardstick of comparison. The paper finds that most mining firms have adopted voluntary waste management practices due to their concern for stakeholders and potential financial benefits, while the mandatory waste management practices ...

The major aim of this paper is to investigate whether such practices have a close relationship with the mining firm's financial performance (represented by return on equity [roe]). The approach is a case study of a South African mining firm listed under the socially responsible index (sri) of the Johannesburg Stock Exchange (jse). It uses Green-Steel sa (pseudonym used in place of the real name) as a case study. Using multiple regression statistics, the return on equity of Green-Steel sa is regressed on three environmental management practices of GreenSteel (carbon reduction, energy efficiency, and water usage). The result shows there is no significant relationship between the variables and this lends credence to information gathered from Green-Steel environmental reports that Green-Steel's environmental management practices are driven mostly by...

Previous studies focused more on disclosure or international research but none focused on this impact in JSE SRI South African mining firms hence this study attempted to fill this gap. Using a mixed methods approach, the study examined whether the firms' carbon emissions, energy usage and water usage had any impact on the firms' return on equity. The study concluded that Environmental Management Practices did impact firms' financial performance and offers many opportunities for academia, industry, managers, regulators and society to use these findings as a means for more research into and better understanding of these environmental management practices and their potential benefits to society.

This article examines issues of governance by establishing the relationship between CSR and return on assets (ROA) of Johannesburg Security Exchange (JSE) listed mining firms. The purpose of focusing on mining firms is necessitated by the need to address socioeconomic ills which are phenomenal within the South Africa’s mining communities. Hence, the objective of this article is to investigate the interactions in the CSR, based on employees and black suppliers. The secondary data on CSR and ROA for the years 2010–2014 were collected from the integrated reports of purposively sampled 10 mining firms listed on JSE (SRI) Index. The case study research strategy was adopted from which data was collected and gathered using content analysis. The CSR aggregates such as Broad Based Black Economic Empowerment (BBBEE) procurement and skill and train...

To promote corporate environmental management practices and green economic development, governments enact legislation aimed at curtailing damage to the environment; in addition to government regulation, some firms apply voluntary self-regulatory measures to limit their impact on local environments. This paper will critically review literature on current environmental management practices and their role on sustainable development. Based on the literature review of different sections of society, preliminary findings suggest that current environmental management practices have dissimilar effects on sustainable development. These practices in the fields of health and law are more indicative of policy based practices, while those in engineering and industry are more hands on. This paper concludes by recommending that these environmental management practices be harmonized across the different se...

Furthermore, there are greater environmental, economic, and social demands on firms to reduce the environmental impacts due to environmental problems brought about by their operating activities. There is a current debate as to the financial implications of waste management expenditure on waste reduction targets. This study examines the relationship between waste management expenditure on waste reduction targets, and the impact of waste reduction targets on firms' profitability. This study used the quantitative method that utilizes the multiple regressions method to analyses data from selected South African Johannesburg Stock Exchange's (JSE) Socially Responsible Index (SRI) listed manufacturing and mining firms for ten years (2007-2016). The study tests if there is a relationship between waste management expenditure and waste reduction targets, as well as the impact of waste reduction targets on firms' profitability. Results show that waste reduction targets have a positive, but insignificant, correlation on the profitability of firms, and also indicate that there is a relationship between waste management expenditure and waste reduction targets. The study recommends that firms should focus more on minimizing waste generation to reduce costs.
