What motivates and inhibits Indian textile firms to embrace sustainability?

Our study identifies the motivations and barriers to pursue sustainability for textile firms in India and the impact of these factors on firm’s adoption of sustainable business practices. Our study is based on primary survey of 113 managers from textile firm who are responsible for taking decisions towards formulation of business policies, and drivers are the reasons why companies decide to pursue sustainable practices. Regression analysis shows that regulatory, market and economic factors are more significant in pushing firms to adopt sustainable practices, whereas initial cost of compliance is the biggest challenge in implementing these practices. The results of the study are extremely important in assisting firm managers in enhancing their understanding of factors for a successful environmental strategy and influencing them to embrace sustainability. The study also contributes to our understanding of environmental issues in textile supply chain and how it could be made environmentally more sustainable. Finally, implications to extend research on role of internal actors in the organisation in shaping and implementing environmental strategies are presented.


Introduction
Textiles and Apparel (T&A) sector is one of the most significant industrial sectors and plays a major role towards contribution to national economy, employment generation and exports in developing countries (Karthik and Gopalakrishnan 2014). The worth of global textile industry is US$ 2.5 trillion worldwide with 58% contribution from apparel sector and 42% share from textile sector. Amongst the major exporters of Textile & Apparels (T&A) globally, the top 10 exporting countries enjoy a share of 72% in global T&A exports with China and Hong Kong maintaining the top position with 37% share, followed by India with a share of 5% in 2017. It is then followed by Bangladesh, Germany, Italy, Vietnam and Turkey each having a share of 4% (Ministry of Textile, Annual report 2017-2018).
Though, recognized as one of the most important industries from the economic point of view, at the same time this industry is subject to severe ecological and social problems throughout the supply chain (Shen et al. 2017;Allwood et al. 2015;Alkaya and Demirer 2014;Bonini et al. 2006; Defra (UK Department for Environment, Food and Rural Affairs) 2008). The main environmental problem associated with textile industry consists of water body pollution caused by discharge of untreated effluents. During production, the cloth passes through the various processes and chemical operations like sizing, desizing, bleaching, dyeing, printing and finishing and several dyes, chemicals are used in desired quality in fabrics and this causes environmental problems unless it is properly treated before disposal (Hasanbeigi and Price 2012;Dasgupta et al. 2015). The industry also generates air pollution prior to processing of fibres and during spinning and weaving it generates dust, cotton lint etc., which degrades working environment in the industry (Blackburn 2009;Allwood et al. 2008). Owing to these severe ecological impacts, the textile industry is counted amongst the heavily polluting industries. Earlier the concern for the environment was the most neglected area of the textile industry but with growing awareness on environmental protection due to the depletion of non-renewable resources, global warming and destruction to ecology (Kalliala and Talvenmaa 2000;Kane 2001;Da Silva and Teixeira 2008;Thiry 2011), this issue has gained acceptance worldwide that there is a need for more responsible approach to the environment.
The structural change within the industry is visible globally and the production of textile and clothing has increased significantly. India has second largest population in the world and hence, the demand for textile products in India is very large and is growing at an increasing rate (Assocham, 2010). As far as economy is concerned, over 45 million people in India are directly employed by the textile industry. Also, the business model for the textile industry is primarily export-oriented as India is the second-largest textile manufacturer and exporter in the world (Ministry of Textiles, 2017). India is also amongst the world's top producers of yarn and fabrics and second highest producer of cotton after China contributing about 21.5% of the world's total production (Ministry of Textiles, 2018). The presence of more than 3000 spinning and composite mills spread across the country makes India an outsourcing hub for the global textile and apparel supply chain (CITI 2018;Baskaran et al. 2012;Verma 2002). With huge economies of scale, low-cost labor force, sufficiency in raw materials and spinning capacities, India has emerged as one of the major players for various international brands and retailers as it's textile and clothing industry has shown steady growth in past few years (Gupta and Hodges 2012).
Being a diverse and heterogeneous sector by nature, the textile industry consists of traditional textiles and technical textiles. In general, the textile industry provides textile material for apparels. This segment is known as traditional textiles which consists of raw materials such as cotton, jute, silk wool etc., as it fulfils the basic needs of human beings. The textile industry can further be classified into two categories, the organized mill sector and the unorganized decentralized sector. The organized sector of textile industry represents the mills it could be a spinning mill 1 or a composite mill 2 (Simi 2012;Chugan 2011). Cotton is one of the most important cash crops and accounts for around 25% of the total global fibre production. The environmental issues associated with cotton production are humongous. More chemicals are used for cotton than for any other crop and its production requires immense quantities of water along with use of pesticides that contaminates the freshwater availability, thereby causing water pollution (Karthik and Gopalakrishnan 2014;G. Hansen and Schaltegger 2013). India is ranked first in the world in terms of cotton acreage with around 10.5 million hectares under cotton cultivation which is around 35% of the world area. Emergence of environmental standards and labels along with the need for improvement on production and processing practices have further aggravated the prospects of the Indian cotton textile industry (Singh et al. 2013;Parvathi et al. 2009). Thus, addressing these sustainability issues and balancing the Triple bottom line (TBL) presents various opportunities and challenges for firms towards engaging in sustainability-oriented practices (Joyce and Paquin 2016;Akenji and Bengtsson 2014). Research in several industrial sectors (Dos Santos et al. 2007;Brunke et al. 2014;Beske et al. 2014;Sezen and Çankaya 2013;Tortella and Tirado 2011;Pullman et al. 2009;Chkanikova and Mont 2015) shows that firm managers' environmental attitude to be positively correlated to the adoption of sustainable business practices in the industry (DeSimone andPopoff, 1998 andClemens 2001). Their perception towards sustainable business practices influences the formulation of business policies for a positive environmental impact (De Abreu 2015;Caniato et al. 2012;Arora et al. 2004;Rieple and Singh 2010). Towards taking this decision to improve their environmental performance, the managers are motivated by various factors such as preservation of resources (Theyel 2000;Goworek et al. 2012;Pedersen and Andersen 2014), legal regulations (Jeswani et al. 2008;Babiak and Trendafilov 2011), to enhancing its reputation and differentiating its product in the market (Chkanikova and Mont 2015;Jeswani et al. 2008;Søgaard Jørgensen et al. 2010;Wuet al. 2012). The road to sustainability, however, is not easy as firms encounter various internal and external constraints in form of cost (Schrettle, S. et al., 2014;Wu-et al. 2012), absence of mandatory regulations and policies towards implementation of environment friendly practices by government bodies and lack of requisite skills and capacities (Achabou and Dekhili 2015;Jeswani et al. 2008). These factors restrict firm mangers in adopting sustainable practices.
While examining the literature on textile industry (Shen et al. 2017;Achabou and Dekhili 2015;Allwood et al. 2015;Alkaya and Demirer 2014;Shen 2014;Abernathy et al. 2006;Herva et al. 2008;Gardetti and Torres 2017;G. Hansen and Schaltegger 2013;Goworek et al. 2012;Dasgupta et al. 2015;Diabat et al. 2014;Resta et al. 2013;Chico et al. 2013;Nieminen et al. 2007;Hong et al. 2010;Wenzel and Knudsen, 2005;Chiarini 2014), we came across two significant gaps on environmental management practices for textile industry: First, most of the primary surveys with the firm managers in context of textile industry are conducted in developed countries such as Europe, USA, Australia, UK and Denmark, whereas the research in the context of emerging economies like India remains highly unexplored (Gardetti and Torres 2017; Vajnhandl and Valh 2014;G. Hansen and Schaltegger 2013;Goworek et al. 2012;Joergens 2006). A lot of production centers are concentrated in developing countries like India, Bangladesh, Pakistan, and the research for these geographical regions is scanty. Secondly, previous studies reported in India focused largely upon technological as well as economic aspects of textile industry (Dasgupta et al. 2015;Diabat et al. 2014;Hiremath et al. 2012;Reddy and Ray 2011;Verma 2002;Shrivastava, 1995;Narayanaswamy and Scott 2001) whereas, we find hardly any study capturing the managerial perspective towards sustainability issues and practices from the textile sector in India. Thus, leaving a Sharma and Narula Asian Journal of Sustainability and Social Responsibility (2020) 5:6 Page 3 of 23 research gap to understand the organizational issues across the multiple states in the second largest cotton producer of the world i.e. India. Our study addresses these gaps by assessing the nature and extent to which adoption of sustainable business practices are affected by drivers and barriers for the textile industry. This study is significant keeping in view the momentum which is picking up with regards to the global markets and the standards they demand. Sometimes, firms in these countries are unable to lead up to these specifications. It is, hence, worthwhile to understand the motivations behind environmental adoption and barriers they encounter to pursue environmental practices. A lot of other South Asian countries are also engaged in similar exporting activities, the findings may not only be relevant for India but also for other textile producing countries including Bangladesh, Pakistan, etc. Previous research has also demanded that these issues to be examined in the context of developing countries (Lozano 2013;Wu-et al. 2012;Jeswani et al. 2008: Desore andNarula 2018). Thus, the primary aim of this research is to explore the motivations and barriers in adoption of environmentally sustainable strategies for the Indian textile industry. Our paper is divided into six sections. In the first section, we briefly discuss the background in the context of the Indian textile sector. The second section presents a literature review on motivations and barriers for firms to embrace sustainability with special reference to the said sector. The detailed methodology for this study is discussed in section three. Results and analysis of our research are presented in section four and in the last section, we conclude by providing both managerial and research implications to advance future research in the area.

Theoretical background
The concept of sustainable business practices Sustainability is taking from the earth only those resources that are easily renewable while doing no harm to the environment. This allows for the needs of the current generation to be met without affecting the potential needs of future generations (World Commission on Environment and Development, 1987 (WECD). Sustainable business revolves around the three Ps: People, Profit and Planet (Elkington 1998). Many authors have tried to define sustainable business from various dimensions like greening the production process, to working on supply chain and to adopting sustainability strategies. For instance, authors Eccles et al. (2012), defines sustainable business as a business that carries environment friendly business processes without leaving negative environmental impacts related to their activities, products and services thereby leading to cost savings, enhancement of firm's image and better risk management. Authors Azapagic and Perdan (2000); Welford (2005) defines "Sustainable business as a new, radical paradigm that considers the ecological, social and economic impacts in a way that will not compromise the needs of the future generations". The triple bottom line (TBL) perspective is relatively widely understood perspective for business models to support sustainable actions (Joyce and Paquin 2016). For any product to be sustainable, it needs not only to be profitable but also take into consideration environmental and social impact during its lifetime.
Some authors have also tried to define the sustainability in context of textile industry. For instance, as defined by Fletcher (2009), "A sustainable product is one that is manufactured in such a way that it has lowest possible adverse effect on the environment. e.g. by making the most efficient use of resources such as water and energy and which goes the extra mile to recover raw materials, e.g. by the recycling of as much water as possible or by recovering the heat from wastewater discharges". According to Hethorn and Ulasewicz (2008), sustainability within fashion means that "through the development and use of a thing or process, there is no harm done to the people or the planet and that thing or process, once put into action can enhance the well-being of the people who interact with it and the environment it is developed and used within." For our study, we have considered the definition given by authors Gardetti and Torres (2012), to define sustainability in context of textile industry. They define sustainability for the textile industry as a "means to reduce water use and wastage across the supply chain, reduction in chemical pollution and minimized the use of non-renewable sources". The textile industry is subject to severe ecological problems in most of the phases of supply chain. Sustainability issues concerning the textile supply chain are related to energy efficiency, water management, waste management, logistics from raw material procurement to textile production until fabric finishing. As per Chen and Burns (2006), full environmental impact of any textile product may be broken down into those associated with its production (renewability of raw materials and chemicals released during production and processing), maintainance (quality and nature of chemicals used for laundering and dry cleaning) and eventual disposal (products recyclability and biodegradability), this indicates that making production process sustainable can help to reduce resource consumption, waste generation and other associated costs for textile firms.
Literature presents various sustainability practices adopted by firms towards improving their environmental performance (Gardetti and Torres 2017; Resta et al. 2013;Fletcher 2008;Fletcher and Grose 2012;Zhu and Geng 2013). For instance, in a study on textile industry by authors Zabaniotou and Andreou (2010), firms reported use of waste generated during ginning of cotton to develop an alternative energy source for reduction of Greenhouse Gas (GHG) emissions. Chinese researchers (Hasanbeigi and Price 2012) reviewed and summarized various energy use and energy efficiency technologies and measures applicable to textile industry at each stage of spinning (high speed carding machines, use of light weight bobbins in ring frame), weaving (replacing the electrical heating system with steam heating systems for yarn polishing machines), wet processing (recover heat from hot rinse water, reuse of washing and rising water, discontinuous dyeing with airflow dyeing machine) and fibre production (use of light weight carbon reinforced spinning pot in place of steel reinforced pot, adoption of pressure control systems with variable frequency drive (VFD) in washing pumps in after treatment process etc.) which resulted in considerable reduction in total energy consumption and associated co 2 emissions of company within a time frame of less than 1 year. Towards water efficiency in textile production, authors Alkaya and Demirer (2014), proposed and implemented five sustainable production applications such as use of drop/fill washing method 3 instead of overflow, reuse of stenter/ singeing cooling water, renovation of water softening system and various valves and fittings in water transmission system which further resulted in reduction of water consumption, wastewater generation and energy consumption and helped manufacturing mill achieve various environmental and economic benefits. Product life cycles are shortening, and companies want to substitute their products at an increasing pace. Another study on sustainability transformation showed that by diversifying into new environmental markets (organic fibres) and redesigning products to be more environmentally sensitive (integrated production of natural fibres, replacement of natural fibres with artificial fibres etc) resulted in reduction of environmental impacts by using less pesticides and chemical fertilizers and also social benefits in form of eliminated health threats of pesticides and better working conditions (G. Hansen and Schaltegger 2013). Some empirical studies reported in literature have addressed sustainability issues based on application of green certifications by firms such as ISO 14000,Global organic textile standards (GOTS), 4 implementation of principles given by Global reporting initiative (GRI), use of ecolabels, Oeko tex 5 100 (Almeida 2015;De Brito et al. 2008) and green product and process design considering the production technologies, the product characteristics and materials used (Niinimäki and Hassi 2011;Ozturk et al. 2015). The previous authors also proposed various strategies to make textile supply chains sustainable. For instance, for a study on Taiwan textile and apparel industry, factors such as green purchasing, cooperation with customers and eco-design were proposed as ways to implement Green Supply Chain Management (GSCM) practices (Wu-et al. 2012). In another study, authors investigated China's textile industry in addition to the automobile, power generating, chemical, and electric industry and suggested supplier collaboration, ecodesign and internal environmental management to implement GSCM practices (Zhu et al. 2005;Zhu and Sarkis 2006).
Researchers have also made efforts to study Indian textile industry from sustainability lens, for example, Baskaran et al. (2012), evaluated garment manufacturers and ancillary suppliers within Indian textile industry using the sustainability criteria for social factors (discrimination, abuse, human rights, pollution) in Tirupur city and made efforts to answer the questions related to challenges faced by the manufacturers to adopt sustainable practices towards exporting garments to foreign buyers. In another study, Rieple and Singh (2010), presented the value chain analysis for production of organic cotton tshirts thereby discussing the areas of inefficiency during each stage of production process for its UK and US retailers where they reported that use of organic cotton by firms resulted in lower cost of pest management, increased yield and reduced crop failure in the long run. A case study on city of Solapur in the state of Maharashtra was carried by Hiremath et al. (2012), to measure the impacts of textile industry on the environment, human health, biodiversity and the climate. The authors suggested a sustainable networking model with integration of information and communication technology (ICT) for mitigating the change and to achieve desired development goals. A study by authors Dasgupta et al. (2015), provided various technological insights towards effluent treatment for the textile industry consisting of membrane filtration, biological treatments, oxidation and crystallization etc. Thus, summarising the previous studies, we find limited research on analysing the intent for sustainability for Indian textile industry in comparison to the studies reported from other developed countries in this sector discussed above. Previous studies mainly examined the factors from developed country perspective and were mostly qualitative in nature. In light of absence of any comprehensive studies on the subject in developing countries, our paper addresses this gap and considers factors related to the product, process and supply chain by firms to implement sustainable practices.

Drivers and barriers to sustainable business practices
We define drivers as the reasons behind firm managers' decision to pursue sustainable practices and in the process, they face certain challenges or barriers to adopting these practices. These factors tend to shape the organizational strategy and have the power to influence the response of the firms (Babiak and Trendafilov 2011;Caniato et al. 2012;Elliot, 2013;Lozano 2013). Involvement and pressure from regulatory bodies towards environmental clearance have been reported by researchers as a significant driver towards motivating firm managers to adopt environment-friendly practices (Jeswani et al. 2008;Babiak and Trendafilov 2011;Lozano 2013;Ervin et al. 2013). Regulatory pressure has been a coercive power pushing firm managers to adhere to the environmental requirements (Delmas and Toffel 2004). Government support to textile companies towards their technological improvements, investment in R&D and dyeing capabilities have led to various energy and carbon reductions in the industry (Wu-et al. 2012). Various environmental certification standards have also been proposed by environmental groups such as ISO 140001; Oeko tex 100, GOTS (Global organic textile standards), BCI (Better cotton initiative), etc., which restrict the use of hazardous materials and processes towards textile and clothing manufacturing thereby resulting in regulatory pressure. Various market related factors in form of competition and demand from buyers and manufacturers (Daub and Ergenzinger 2005), motive to gain a unique green position in the market and to improve company's reputation (Chkanikova and Mont 2015;Jeswani et al. 2008;Søgaard Jørgensen et al. 2010;Wu-et al. 2012) have also been reported to be of significant importance towards influencing the firm managers decision towards sustainable practices. Literature shows that (Christmann and Taylor 2001;O'Cass and Weerawardena 2010; G. Hansen and Schaltegger 2013) a higher level of competitive influences resulted in the development of competitive products (use of organic cotton waste to make bags, T-shirts), strengthened managers commitment towards environmental protection (Menguc et al. 2010). For some studies, competitive influences resulted in influencing firm managers to imitate and learn environmental management practices from its competitors and further resulted in the efficient utilization of firm's resources and improved performance. Various organizational factors in form of commitment from top management towards integrating sustainability into business practices, knowledge sharing and training to employees (Petrini and Pozzebon 2010;Wu-et al. 2012;Min and Galle 2001;Walker et al. 2008) have been found to be influencing firm performance. Firms response is also reported to be influenced by institutional members as it can change firms' viewpoints in terms of the cost involved and benefit achieved through environmental management (Nhemachena and Murimbika 2018;Zhu and Geng 2013;Sarkis et al. 2010;Lee 2008). Firm managers face various challenges while implementing sustainable practices most of which are related to the lack of financial and technical resources. As per the previous literature, excessive cost of raw materials and Sharma and Narula Asian Journal of Sustainability and Social Responsibility (2020) 5:6 Page 7 of 23 lack of financial resources is reported to be the most significant barrier faced by firms towards implementing sustainable practices (Lo et al. 2012;Na and Na 2015;Mittal and Sangwan 2014). Factors such as subsidized prices, inflation rate, and lack of enough infrastructure makes it even more difficult for firms to overcome the cost barrier (Gardetti and Torres 2017; Worrell et al. 2003;Jeswani et al. 2008;Chkanikova and Mont 2015). Alongside, factors such as the absence of mandatory regulations and policies towards the implementation of environment-friendly practices act as a barrier for firms. For developing countries, lack of requisite skills and expertise to adapt the technology to local conditions is considered as another important barrier hampering the growth of firms (TERI 1997;Jeswani et al. 2008).
Summarizing the literature, we find that industrial response towards environmental practices varies significantly across sectors and countries (Nhemachena and Murimbika 2018;Chico et al. 2013;Chiarini 2014;Van der Woerd et al. 2004). Factors influencing these responses revolve around various drivers and barriers in the form of regulations, economic conditions, market related factors and managerial, organizational aspects that help firm managers to implement sustainable business practices. Based on the discussion above, this research presents the following hypotheses; H1. Regulatory pressure by the government, competitive influences and market demand positively influences the adoption of sustainable business practices by the Indian textile firm managers.
H2. Firms that face a lower level of economic, managerial, organizational, regulatory barriers are more likely to adopt sustainable practices.

Methodology
The section below discusses at length about questionnaire development, data collection methods and analysis tools used for this study.

Instrument development
We used a structured questionnaire to collect the data based on the primary survey, as this research design has successfully been used in similar previous studies (Theyel 2000; Wu-et al. 2012;Brunke et al. 2014). The items (questions) of the questionnaire were derived from previous literature and characteristics of textile industry.
The explanatory variables in this study include a set of drivers and barriers that influences the sustainable business practices of the textile companies. In order to assess the drivers, the questionnaire included items related to regulatory pressure, market competition and market demand. The items used in our study were adapted from previous studies (Wu-et al. 2012;Zhu et al. 2007). Similarly, for the barriers, we identified and modified items for managerial and organizational barriers (Trianni et al. 2013, J-C. Brunke et al. 2014;Ervin et al. 2013;Cagno et al. 2013;Rhodin et al. 2006;Harrington et al. 2008). For the dependent variable, we used a set of eighteen sustainable business practices items that are related to the product, process and supply chain by firms to implement sustainable practices (modified from Caniato et al. 2012). All items of the questionnaire were measured using 1-5 Likert type scale questions with choices -1 (strongly disagree); 2 (disagree); 3 (Neutral); 4(agree); 5(strongly agree).
After the questionnaire was developed, it was reviewed by the subject experts and revised. The questionnaire was then pretested with on Indian textile industry experts, Sharma and Narula Asian Journal of Sustainability and Social Responsibility (2020) 5:6 Page 8 of 23 including three textile industry senior managers, one textile industry consultant with expertise in providing end to end solutions spanning the complete business cycles in the textile value chain and two academicians. Based on their feedback, the questionnaire was further revised before administering to the respondents (firm managers).

Respondents
The target respondents included of executives and senior-level managers with titles such as managing director, production heads, plant managers, sustainability head, technical head etc. These respondents were chosen because of their knowledge in textile supply chain operation and strategic management. Out of 202 firms, we could get data from 118 firms from which 113 were found to be complete thus resulting in a response rate of 55.94%. The complete profile of firms and respondents has been displayed below (Table 1) .

Sampling and data collection
Sample selection was done based on a list obtained from Confederation of Indian Textile Industry (CITI) in 2015 enlisting all textile firms on Bombay Stock Exchange (BSE). The list consisted of a total of 291 firms out of which we selected 202 firms which were lying in the north-western states of India, thereby covering 71.83% of total turnover of the textile industry. Only large-scale textile manufacturing firms dealing in cotton and yarn manufacturing (Spinning, weaving) and chemical producing firms (wet processing) were selected as they contribute towards creating more pollution and cotton textile segment accounts for around 75% of the total textile industry. Also, as the maximum number of environmental issues are at the stage of wet processing 6 (which consists of dye houses) so the firms selected for this study also form part of the organized sector comprising of large composite mills 7 and dye houses. For the purpose of this study, all primary data were collected from the identified firms located in all the five major states in North West region (Maharashtra, Gujrat, Rajasthan, Punjab, Delhi). of the country during July 2015-July 2017, . All the identified companies were contacted and invited to participate in the study. After explaining the purpose of the study and seeking informed consent, questionnaires were distributed to all the respondents using three different methods -face to face, telephonic and online. Only those respondents who were willing to participate but were unavailable for face to face or telephonic survey interviews, were considered for online surveys. In addition to the regular questionnaire, a detailed online follow up was done with these respondents. The questionnaire consisted of 5-point Likert scale questions, in the first section, we collected the background information about the organization and on the position of the respondents in the organization, annual turnover, year of firm's establishment. The other sections of questionnaire were based upon drivers motivating firm mangers to take sustainable practices, sustainable business practices adopted by firm managers, barriers in implementation and benefits achieved). The follow up consisted of open-ended questions to gain insight into key areas where textile firms should focus to make their processes sustainable, sustainability initiatives undertaken by them and challenges faced in implementing environmentally sustainable practices.

Description and construction of variables
Dependent variable: Sustainable business practices.
Explanatory variable: Drivers and Barriers.

Explanatory variables
We have identified seven explanatory variables in the form of drivers and barriers to explain the changes in sustainable business practices.

Regulatory pressure
Several reviews of empirical studies suggest regulatory pressure to be positively influencing the firm's efforts towards environmental management (Darnall et al. 2008;Jeswani et al. 2008;Babiak and Trendafilov 2011;Lozano 2013;Ervin et al. 2013). For example, previous studies reported that firm managers were more receptive to regulatory factors and in participating in voluntary environmental programs (Delmas and Toffel 2004;Jeswani et al. 2008). In order to estimate the impact of regulatory pressure on sustainable business practices, we computed an index for regulatory pressure using the following components: national environmental regulations towards water, waste and energy efficiency was the reason to go sustainable; regional environmental regulations towards water, waste and energy efficiency was the reason to go sustainable; industry agreements was the reason for improving environmental performance. Principal component analysis (PCA) was used to derive the index.

Market competition
Competitive influences have been recognized as factors motivating firms to differentiate its product, increase firm's productivity and thereby influence them to adopt environment management practices. Empirical studies have found that market forces in form of competition and demand play an important role in firms' adoption of sustainable practices. Several empirical studies showed that stronger competitive pressure inclined companies to imitate competitor's business model, strengthen its competitive advantage and improve its image and performance (Chkanikova and Mont 2015;Jeswani et al. 2008; Søgaard  Wu-et al. 2012). India holds a significant position in global textile exports and textile manufacturers have to meet the environmental requirements of buyers to maintain its position in the market. This research assumes that market competition can influence firm managers towards improving their environmental performance. We estimated the impact of market competition on the firm's adoption of sustainable practices based on responses from Indian textile firm mangers. We computed an index for market competition using principal component analysis (PCA) using the following components: competitive pressure was the reason for our firm to adopt sustainability; the green initiative (following environmental standards) was part of our group sustainability activities; to maintain competitive position our firm took up sustainability practices.

Demand from foreign buyers
For the component on demand from foreign buyers we have used a dummy variable to represent the attitude of the firm towards a sustainable business practice based on foreign clients. If the domestic firm complies with sustainable practices based on foreign demand then the variable takes the value 1, 0 otherwise. A similar variable was significant in explaining green supply chain practices adopted by textile firms in Taiwan (Wu-et al. 2012). Previous research (Menguc et al. 2010) has shown market pressure to be positively influencing the firms managers commitment towards environmental protection, increasing investment in environmental management practices and encouraged environmental collaborations, thus we estimate a positive relationship between the impact of "demand from foreign buyers" on sustainable business practices.

Managerial barriers
Empirical studies suggest that manager's attitude and commitment play an important role in firms' adoption of environmental management practices and decision making (Petrini and Pozzebon 2010;Wu-et al. 2012;Min and Galle 2001;Walker et al. 2008). We attempted to estimate the impact of managerial barriers on the firm's adoption of sustainable business practices. We computed an index for managerial barriers using principal component analysis (PCA) using following components: lack of internal expertise on the environmental issue; lack of qualified human resources and capabilities to deal with environmental issues; lack of support from top management; communication gap from top management.

Organizational barriers
Adoption of sustainable business practices may also be influenced by firms' technological capabilities. Some studies suggest that firms with higher R&D facilities could adopt more pollution prevention strategies towards greening their production chain (Harrington et al. 2008;Ervin et al. 2013). We computed an index for organizational barrier using principal component analysis. The components used are lack of internal technological facilities; lack of R&D facilities; no specific benchmarking tool.

Weak regulations
For the component on weak regulations, we have used a dummy variable to capture the response of firms, If the domestic firm faces lack of support and information from Sharma and Narula Asian Journal of Sustainability and Social Responsibility (2020) 5:6 Page 11 of 23 the government to comply with sustainable practices then the variable takes the value as 1, 0 otherwise.

Economic barriers
For the component on economic barriers, we have used a dummy variable if the firm faces economic barriers like the high cost of implementation and lack of financial resources, the variable takes the value 1, 0 otherwise.

Sustainable business practices (SBP)
We have measured the intensity of sustainable business practice with an index constructed using principal component analysis (PCA) of the responses to several questions regarding sustainable practices. The components used are presented in Table 3 below.

Descriptive statistics analysis
Table 2 and 3 below shows the descriptive statistics analysis which contains the mean, standard deviation, and number of samples for both explanatory and dependent variables. Except for managerial and organizational barriers, the mean of all other factors is greater than 3 of on a 5-point Likert scale. Demand from foreign buyers is highest amongst drivers and the economic barrier is the highest scale amongst barriers.

Data analysis
For this study, data were edited and scrutinized for correction and consistency. The principal component analysis was conducted in SPSS (version 17.0) to compute the indices for explanatory and dependent variables. PCA optimally weights chosen observed variables and combines them linearly to create new variables (Kennedy, 2003). Multiple linear Regression analysis was used to estimate the relationships between the dependent (sustainable business practices) and explanatory variables (drivers and barriers) using STATA 12 software. We have run a model using the variables in their level form except for the two variables which we transformed into their log forms, namely, market competition and managerial barriers. Since these variables varied significantly in their scales when compared with the dependent variable, we had to transform the variables into a log form.
Multicollinearity and heteroscedasticity are often observed in estimations based on multivariate linear regression analysis. Multicollinearity was tested using the variance inflation factor (VIF). A low value of mean VIF (1.86) which is less than 10 indicates no problem of multicollinearity in the model. Breusch-Pagan / Cook Weisberg test was used to address the potential problem of heteroscedasticity. The Breusch -pagan heteroscedasticity indicated a higher probability value (0.2266) than chi-square (1.46) implying that the null hypothesis H0 is not rejected and our results indicate an absence of heteroscedasticity.

Results and discussion
We estimated seven determinants of sustainable business practices for the Indian textile industry. These are the drivers and barriers which form the independent variables used in our analysis to study their impact on sustainable business practices (SBP). Results for the multiple linear regression analysis are presented in Table 4 below.
The regression model showed 75% (R 2 = 0.75) variation in the adoption of sustainable business practices due to the determining drivers and barriers. The variable regulatory pressure indicates a significant and positive impact on the adoption of sustainable business practices at 1% significance level. This outcome suggests that environmental regulations by the government leads to an increase in the willingness of Indian textile firm managers to implement these practices and help them improve their environmental performance. During the survey, firm managers reported that launch of various initiatives by the Government of India such as introduction of Integrated Processing Development Scheme (IPDS) are the reasons behind firms initiative to follow environmental standards.

Often, productivity of textile industry is affected using obsolete machinery and outdated technology. Another initiative by the government in form of Amended Technology Upgradation Funds Scheme (ATUFS) provides subsidy to the textile firms towards technology upgradation. The effect of pressure from regulatory bodies shows that firms are willing to allocate resources to prevent environmental degradation with adequate support from government schemes, despite the cost constraints faced by them. They perceive pressure from regulations as opportunities to be more environmentally sustainable rather than taking it as threats. This result is coherent with previous findings (WU, G -C.et al. 2012;Darnall et al. 2008;Darnall and Edwards Jr 2006;Ervin et al. 2013), which revealed regulatory pressure as a significant motivator towards the adoption of environmental practices. Furthermore, our results show that market competition impacts adoption of sustainable business practices at a 5% significance level. In the recent years, major global textile and clothing brands have started their operations in India (H&M, GAP, Levis, Addidas, Nike etc). These international brands are often more willing to follow environmental regulations and have the brand value to influence market towards adoption of environmentally sustainable practices. This indicates that firm managers often follow suit and develop an environmental strategy based upon global competitors. During the survey, textile firm managers reported initiatives such as establishing long term contractual relations with their vendors, contractors and agencies with established credentials on waste recycling towards improving environmental performance. They also reported initiative undertaken by them to ensure sustainability wherein waste generated during spinning of cotton is sold for further use for making low grade yarns and other home furnishing items. These initiatives help firms to diversify into new market segments, experience expansion of its global and domestic business, and as a result maintain its competitive position and experience an increase in market share. Firm managers also reported following textile standards during production process such as GOTS (Global Organic Textile Standards) and BCI (Better Cotton Initiative) during production. These standards define worldwide recognised requirements that ensure organic status of textiles including ecological and social criteria backed up by independent certification of the entire textile supply chain. These standards enable textile processors and manufacturers to export their organic fabrics with one certification accepted in all major markets, thereby resulting in expansion of business and overall profits for the firms. The variable demand from foreign buyers is found to be highly significant at 5% significance level with a positive sign which suggests that Indian textile firm managers develop an environmental strategy based on the encouragement from its buyers. Textiles are one of the oldest exports from India and the textile sector is one of the biggest beneficiaries of the Merchandise Exports from India Scheme 8 (MEIS) (Ministry of Textiles, 2017), which offsets infrastructural inefficiencies and associated costs in export of goods. India holds a dominant position in the global textile exports, and textile manufacturers must meet the environmental requirements of domestic and international buyers. These results are also coherent with previous findings for various industrial sectors (Zhu et al. 2007;Jeswani et al. 2008;Ervin et al. 2013;Prakash and Potoski 2007;Handfield et al. 2005). Together these results indicate that market forces in form of competition and demand positively influences firm managers decisions to adopt sustainable practices.
Results show that economic barriers negatively affect the adoption of sustainable business practices with 5% significance level. Firms facing economic barriers in the form of high implementation cost and lack of financial resources are less likely to adopt these practices. The textile industry is capital intensive and financial recovery takes time. Indian textile firms often tend to adopt low cost technological options for production as they face monetary challenges in terms of limited resources and capital to invest in high cost technological upgradation. This result is consistent with previous findings that have reported cost constraints to be significant barriers faced by firm managers to implement environmental practices (Ervin et al. 2013;Johnstone and Labonne 2009;Jeswani et al. 2008). In contrast to the results discussed above, our study shows that managerial and organizational barriers reported amongst internal factors affecting the response of firms for developed countries are found to be statistically insignificant in the context of Indian textile firms. These barriers consist of factors such as lack of internal expertise on environmental issues, lack of qualified human resources and capabilities to deal with environmental issues, lack of support from top management, and communication gap from top management. The possible reason for these findings could be that the Indian textile firm mangers are in their initial phase of incorporating these practices. Also, the difference in economic and institutional pressures faced by firms in emerging economies as compared to developed nations could lead to this statistical trend. These findings are however consistent with similar studies on comparison of corporate response towards adopting environment management practices between developing and developed country (Jeswani et al. 2008;Prakash and Potoski 2007), where similar factors were reported to be insignificant from a developing country's perspective.
Overall, the result suggests that regulatory pressure, market competition, demand from foreign buyers and economic barriers significantly impacts the adoption of sustainable business practices for Indian textile firms. Thus, this model helps us better understand, while government policies and market forces play a significant role in motivating the Indian textile firms to embrace sustainability, economic barriers dampen this sustainable growth. Table 5 below presents a set of sustainable business practices adopted by firm managers towards improving its environmental performance .

Conclusion and managerial implications
This research contributes to the empirical findings in the context of textile firms on drivers and barriers affecting adoption of environmentally sustainable practices. The textile industry was chosen for its unavoidable set of sustainability issues on the environmental front. Our study concludes that Indian textile industry firm managers understand and accept that the issue of the natural environment and its protection is important for the performance and development of the textile industry. The empirical analysis of this research indicates that for Indian textile firms, a diverse set of factors consisting of regulatory, market and economic factors are more significant in pushing firms to adopt sustainable practices, whereas internal managerial and organizational barriers are not found to be significantly influencing the firm's practices. Thus, it is evident that the pressure on sustainability in textile firms comes from external factors Sharma and Narula Asian Journal of Sustainability and Social Responsibility (2020) 5:6 Page 16 of 23 rather than internal ones. However, internal factors if addressed would play a significant role in taking sustainability ahead in these firms. Based on this, we stress on giving more emphasis on the role of regulatory bodies to further strengthen the scope of sustainability for textile firms. The managers should also in-plug a sustainable business strategy from the very initial stages to help create that identity. Awareness of sustainable practices should be made part of the training. In terms of regulations and cost constraints, the initial cost of compliance is the biggest challenge in implementing these practices. Apart from this, unpredictable policy change, low enforcement and awareness make it less acceptable among the manufacturers, hence there is a need to regulate cost. The textile associations should come up with specific policies concerning the issues in textile industry and help the government in chalking out these policies. Government must provide subsidies for companies willing to adopt environmental measures say for e.g. if some firm has established an Effluent treatment plant (ETP) then some reduction in subsidy should be given. Also, there should be no segregation between the interests of domestic and foreign buyers from the managerial end, once these are taken care of then the focus will come on including pollution prevention techniques. For example, for dyeing of clothes, two types of bleach chlorine vs peroxide bleach are being used. Chlorine is harmful so it is not used by textile manufacturers for export as it is restricted under environmental guidelines by foreign buyers whereas peroxide bleach is a costly option so used in less quantity for home country production due to lack of stringent regulation. We recommend that strengthening of national and regional regulations will assist companies in adopting the proactive environmental strategy thereby assisting in making optimal choices and dedicating themselves to more comprehensive environmental practices. Sharma and Narula Asian Journal of Sustainability and Social Responsibility (2020) 5:6 Implications for future research Through our research, we contribute to the existing literature on motivations and barriers to pursuing environmental sustainability by the firm. We specifically address these issues concerning the textile industry in India. Given the significance of the industry from the perspective of global demand and sustainable consumption and production (SDG 12), our study brings interesting findings related to firms' strategies and intent behind these strategies. The study gives answers to the questions: Why textile firms in India pursue environmental strategies? Which barriers do they face? The study is limited in its understanding of a limited number of barriers and drivers constrained by a limited number of samples. Secondly, we are estimating factors affecting sustainable business practices of the firms. For instance, we tested the hypothesis that a foreign buyer's demand affects the firm's decision regarding sustainable business practices (SBPs). But SBPs of the firms may have an impact on the decision of foreign customers. In such a situation, there is a simultaneous relationship between the explanatory variable and the dependent variable. This makes the explanatory variable endogenous and one of the assumptions of the classical linear regression model gets refuted. Future research can also consider the role of environmental certifications on how it affects the adoption of sustainable practices. Organizational and managerial barriers are found to be insignificant for this study. However, these factors can be compared across textile firms in other developing countries where they may be significant. Future studies may investigate how other stakeholders of the textile supply chain perceive the barriers and what collaborative efforts could be made to remove these barriers. Hence, a more comprehensive study from an internal and external stakeholder perspective could be very useful. Given the financial stress that many textile firms are facing, it would be worthwhile to explore the relationship between indicators of financial sustainability and environmental sustainability. Further studies could study in detail the understanding of these firms about the Sustainable Consumption and Production (SCP) indicators and efforts towards their implementation. A study of both environmental and social indicators could also be useful from the consumer perspective. A few more research problems could be taken up: How is managerial awareness and attitude about the environment leading to influence firms' strategies? What is the relationship between consumers' demand and firms' adoption of sustainable business practices? How are firms' environmental performance and financial performance related and how they influence each other?
