1. Introduction
Traditionally, the performance of business firms was measured based on economic indicators. However, this evaluative approach has now been upgraded to include sustainable performance [
1]. As result, firms now prioritize sustainable performance to meet the demand of some notable stakeholders like regulatory bodies, environmentally concerned institutions, society, etc [
2]. Sustainable performance is inextricably related to Corporate Social Responsibility (CSR), since it helps firms address the environmental and social interests of their stakeholders [
3]. Sustainable performance, indicated by economic, social and environmental indicators, shows the path to solving sustainability challenges, thereby providing organizations with a competitive edge [
4]. To manage sustainable challenges, regulators are pressurizing firms to incorporate social and environmental goals into their economic agenda [
5]. Moreover, the sustainable performance also aids the achievement of Sustainable Development Goals (SDGs), which primarily focus on economic development, extreme poverty elimination, social trust building and protection of the environment [
6].
Many factors contribute to the sustainable practices of business organizations, among which is compliance with ESG principles [
7]. ESG principle is considered a prerequisite for sustainable development of the global economy and society [
8]. Recent threats to the society and environment due to industrialization along with the COVID-19 pandemic have further aroused global interest in ESG [
9]. The three elementary factors of ESG namely environmental, social and governance are considered crucial for investment analysis and decision-making process while evaluating a corporation’s sustainable development [
10,
11,
12,
13]. These three factors quantify the sustainable performance and social influence of business practices. Developments based on ESG principles such as ESG disclosure standards, ESG evaluation systems and ESG index systems are constantly promoting a new pattern of sustainable development since the formal inception of ESG principles in 2004 [
8]. Owing to the wide adoption of ESG in the practical field, global research interest in ESG has increased.
As a crucial determinant of sustainable business practices, ESG has been investigated from the perspective of developed countries. Hussain, Rigoni [
12] analyzed the performance of the triple bottom line to investigate the relationship between corporate governance and Sustainability Performance (SP) in US-based firms; Maali, Rakia [
14] analyzed the mediating role of CSR on the relationship between corporate governance and sustainability performance in the UK; Yang, Du [
15] investigated the impact of changes in clean energy, green financing and economic practices on sustainability performance through ESG performance in G7 countries; Kocmanová and Šimberová [
16] studied the relationship between ESG indicators and sustainability performance in Czech companies; Ye, Song [
17] explored the impact of ESG on sustainability performance, reflected as stock return, in EU members countries. Also, remarkable studies have been conducted to measure the impact of ESG performance on sustainability performance in emerging economies like China [
9,
18,
19] , Brazil [
20,
21], Korea [
22], India [
23,
24], etc. While some studies have also been conducted to address ESG and sustainability performance issues in Bangladesh, an emerging market [
25,
26,
27], less emphasis has been given to exploring such issues in the manufacturing industry. Bangladesh significantly depends on the manufacturing industry, particularly the Ready-Made Garment (RMG) sector, for its forex inflow. It is the 39
th largest economy in the world, with a promising manufacturing industry, which currently contributes a Manufacturing Value Added (MVA) of 20.6% to GDP [
28].
Sustainable business practice has a huge significance for manufacturing industries, since it facilitates their environmental and social compliance. The manufacturing industry tends to generate more negative outcomes on the environment than the service industry, thus necessitating their adoption of sustainable business practices [
12,
29]. Some researchers identified factors like institutional pressure [
30] and green practice[
31] as influencing the sustainability performance of the manufacturing industries in Bangladesh. Earlier studies conducted in developed and emerging economies have demonstrated the influence of ESG principles on sustainable business performance. However, this relationship remained unexplored in the Bangladeshi manufacturing industry, which is known for flaunting its environmental and social requirements. ESG principle could be a panacea for sustainability challenges of the Bangladeshi manufacturing industry, particularly the RMG sector, which is also criticized for the mistreatment of its workers [
32]. The sector was also censured for its violation of local and global labor standards and rights, which jeopardize the safety of its workers. The Rana Plaza collapse, causing the death of 1129 workers in 2013, the Spectrum Sweater collapse in 2005 and the Tazreen Garments Fire in 2012 are some of the unforgettable scary evidence of poor workplace safety in Bangladesh [
33,
34]. Proper compliance with ESG principles could overcome the shortcomings of Bangladeshi manufacturing industries. Thus, this research aims to understand the impact of ESG practices on the sustainable performance of manufacturing industries in Bangladesh. In addition, the study will also examine the mediating impact of innovation performance on the relationship between ESG practice and sustainable performance of the Bangladeshi manufacturing industry, since the adoption of new technologies and development of innovative business models are considered a crucial player in sustainable business development [
3]. The scarcity of resources, considered a notable peril towards the sustainability of the business, is also a major concern of ESG principles and could be resolved through green innovation performance [
35]. However, innovation strategies should be aligned with sustainability goals to reduce negative impacts on the environment [
36]. In addressing the issues identified above, this study will examine the following research questions:
RQ 1: How does ESG performance influence the sustainability performance of the Bangladeshi manufacturing industry?
RQ 2: How does innovation mediates the relationship between ESG initiatives and sustainability performance in the Bangladeshi manufacturing industry?
This study contributes to the existing literature in the following ways. First, most of the research that explores the impact of ESG on sustainability performance were conducted in developed countries, creating a deficit of knowledge on the relationship in the context of developing countries. Therefore, this study attempts to fill this gap by investigating the impact of ESG on the sustainability performance of the Bangladeshi manufacturing industry. Second, prior research recognized the direct and indirect effects of innovation on ESG performance, but no study explores the mediating impact of innovation on the association between ESG and sustainability performance. Hence, this study examines the mediating effect of innovation performance on the relationship between ESG and sustainability performance. Finally, this study will offer worthy insights for owners of Bangladeshi manufacturing industries and policymakers who are deeply concerned about the global acceptability of RMG firms amid their violation of social and environmental interests.
The remainder of the paper is structured as follows:
Section 2 review the literature and develops the research hypotheses. In
section 3, the study describes the sample, variables, empirical models and method. The results are discussed and interpreted in
section 4. Finally,
section 5 presents the conclusion and policy implication.
5. Discussion and Conclusion
The study examines whether ESG performance impacts sustainability performance through the mediating effect of firm innovation in Bangladeshi manufacturing industries. The results revealed that the higher the ESG performance of a firm, the greater its sustainability and innovation performance. Moreover, innovation fully mediates the relationship between ESG initiatives and sustainability performance, indicating that if a firm enhances its innovation performance, its ESG will accelerate sustainability performance.
As exhibited in
Table 2 and
Figure 2, a positive relationship exists between environmental performance, innovation and sustainability performance. The empirical results support hypotheses H1 and H2 and are consistent with the findings of prior literature [
56,
57,
58]. The finding implies that the higher the environmental performance of manufacturing industries, the greater their sustainability performance. In other words, if firms ensure the reduction of air emissions, hazardous and harmful material consumption and frequent environmental accidents through proper resource, energy and waste management, their environmental performance will increase. Moreover, environmental performance enhances firms’ ability to identify the new dimension of environmental knowledge and innovation and use it for providing innovative business solutions and developing products and processes [
62]. Thus, the study evidenced that environmental performance plays a crucial role in making manufacturing firms in Bangladesh more sustainable and innovative.
Similarly, a significant positive relationship was observed between social performance, innovation and sustainability performance, supporting hypotheses, H3 and H4. The result agrees with the studies of Chaim, Muschard [
68], Chams and García-Blandón [
71] and Kim [
72]. The result indicates that if firms improve their human rights, health and safety within their business practices, their social performance will be enhanced [
67]. This advises that firms take necessary initiatives such as the provision of employee training and development, promotion of occupational health and safety, and maintenance of commitment to employee job security and satisfaction as well as community and societal satisfaction to enhance their social performance and in turn achieve long-term sustainability performance. Moreover, social performance enhances firms’ capacity of innovativeness [
83] and creativity [
84]. Therefore, the study documented that social performance plays a significant role in the firms’ achievement of sustainability and innovation performance.
Moreover, the study found a significant positive association between corporate governance performance, innovation performance and sustainability performance, thereby supporting H5 and H6 as well as the findings of prior studies [
88,
89,
90,
91]. As good governance encourages firms to prioritize social and environmental issues, corporate governance can be said to be a determinant of sustainability performance [
94]. The findings suggest that regulatory bodies should monitor the conformance of firms with environmental and social standards to promote sustainable practices. Also, strong corporate governance demands that the board of directors and investors should not only focus on financial performance but also ensure ESG compliance to enhance sustainability performance. The board of directors should also ensure transparency and accountability at all organizational level while promoting environmental compliance to build good governance and ultimately accelerate sustainability performance. Additionally, concentrated ownership could facilitate sustainable innovation, since large stockholders have the power and incentive to encourage management toward innovation [
112,
113]. The findings also suggest that the management of the manufacturing sectors exercise caution when deciding which risk-control tools to implement.
As indicated in the result, a significant positive relationship was observed between innovation performance and sustainability performance, thus validating H7. The survival, success and growth of a firm are highly dependent on its innovation capacity, firm market, and product and process innovation, all of which also contribute to the firm’s sustainability performance [
116,
117]. Moreover, innovation performance provides firms with a more competitive edge in expanding their business operation [
118]. Therefore, firms need to focus on product design and development to satisfy the customers and consequently enhance their sustainability.
Further, the results revealed that innovation performance fully mediates the relationship between ESG and sustainability performance, thus supporting H8, H9 and H10. The study found that ESG performance, directly and indirectly, influences innovation performance, which in turn generates a positive impact on sustainability performance. The findings indicate that if a firm’s ESG performance increases, its innovation performance will improve. Firm innovation is, therefore, considered a crucial factor in ensuring sustainability performance, as it also mediates the effect of ESG performance on firm performance [
136] and other corporate issues [
11]. Through innovation performance, the firm can develop products and sustainable manufacturing processes. Moreover, innovation performance encourages organizational change to achieve sustainability [
121] by controlling negative environmental consequences, conserving natural resources and energy, and ensuring the safety of the workplace [
123]. Innovation performance also helps firms’ management to comply with environmental, social and governance regulations. Due to innovation performance, products are developed and designed in a way that enables their recycling, reuse and decomposition. Additionally, innovation in green technology increases firms’ capacity to satisfy customers with newly designed products, which in turn enhances their competitiveness in the global market. This not only reduces energy consumption and production cost but also enhance firm productivity and financial performance. Therefore, firms should focus on improving their innovation performance to enhance the effect of ESG performance on their sustainability performance.
