The recent years have witnessed a phenomenal change in quantum and pattern of consumption in the
PT
developing nations of the East. Ever increasing consumption is putting a strain on the environment.
RI
The present work delves into understanding the relationship between environmental concerns and
consumer choice behaviour in purchasing green products in the context of India being a large
SC
emerging economy in South East Asia. Attempt has been made to examine the influence of
consumption values on sustainable consumer behaviour across consumer segments with preferential
U
green choice approach difference. Multiple linear regression analysis, one-way analysis of variance
AN
and other standard statistical analysis of the data collected through questionnaire survey have been
M
done. Results indicate that price sensitivity is high regardless of their choice preference. Social value
parameter being the dominant factor influences sustainable consumption behaviour adoption among
D
the green preferential cluster. Consumption values differ significantly across consumers exhibiting
TE
different preference for products with and without green credentials, being higher for those with

1. Introduction
PT
Rapid economic growth has fostered over-consumption and natural resource exploitation leading to
RI
environmental deterioration. The extensive consequences being global warming, environmental
degradation (soil, air, and water), ozone layer depletion and life-threatening health hazards.
SC
Consumption habits of private households significantly contribute to environmental degradation.
Awakened by the severity of environmental deterioration, consumers are gradually changing their
U
attitude, behaviour and approach in matters of consumption.
AN
From 1990s onwards, substantive researches have been undertaken to analyse consumers’ buying
M
behaviour of environment-friendly products (Davis, 1992; Ottman 1993). Products which are
produced without non-toxic chemicals or are recyclable, reusable, bio-degradable or having eco-
D
friendly packaging and with low detrimental environmental impact at all stages of its life-cycle with
TE
the long term goal of preservation of natural environment are termed as green or environment
friendly products (OECD, 2009). Lack of information to the consumers about green products often
EP
results in an attitude-behaviour gap between their environmental concern and actual buying
C
behaviour thus hindering the market share for green products (Ohtomo and Hirose 2007).Consumer
AC
research recognizes consumers’ perception about green products, its price and quality(functional
value),their urge to seek knowledge (Epistemic value),image concern, peer opinion (Social
protective role towards environment (Environmental value)may have strong influence and
prognosticate sustainable consumption behaviour (Laroche et al., 2001; Sharma and Bagoria, 2012).
ACCEPTED MANUSCRIPT
Based on these research a theoretical framework is built to examine the influence of several
consumption values like product quality, price, value-for money, sense of accomplishment,
environmental perceptions, inquisition, contingent circumstances and their trade – offs towards
sustainable consumption practices for consumers’ with choice preference for products with green
PT
credential and those without such preference.
RI
Despite extensive research on consumers’ environmental actions, attitudes and apprehension in the
SC
context of Europe and USA, such studies are remarkably absent in the context of the developing
economies of the East (Schlegelmilch et al., 1994; Minton and Rose, 1997; Arkesteijn and
U
Oerlemens, 2005; Faiers and Neame, 2007; Saxena and Khandelwal, 2010; Boztepe, 2012).
AN
The objective of this paper is to the augment understanding of consumption values reflected in
the demand for green products, and to the suppliers of the products trying to augment their market
TE
share in the market for environmentally sustainable products. Detailed investigation data on two
consumer preferential segments, namely those exhibiting choice preference for products with green
EP
credential and those without green credential will be used in identifying the influence of
consumption values in shrugging off the difference between green preferential and non-green
C
preferential segments.
AC
2. Theoretical background
Based on theoretical perspectives on consumer choice regarding green products, some hypotheses
regarding green product purchase decisions are postulated here in which theoretical underpinnings
for the hypotheses are drawn from the theory of consumer values that recognizes importance of
ACCEPTED MANUSCRIPT
consumption values in green product purchasing decision (Long and Schiffman, 2000; Sweeney and
Soutar 2001; Laroche et al., 2001). Consumer choice is a function of multiple consumption values.
Five such dimensions are functional value, social value, environmental value, conditional value and
knowledge value. This study considers all the five constructs to develop a perceived value scale to
PT
assess sustainable consumption behaviour across two consumer segments.
RI
2.1. Sustainable consumption behaviour
SC
Consumption has various socio-economic impacts, thus following the idea of paradigm shift, new
consumer concerns arise for sustainable consumption. Sustainable consumption refers to the pattern
U
of reduced consumption of natural resources, changing lifestyle and consumption of environment-
AN
friendly products to meet the present needs and aspirations of the future generations. Consumption
and lifestyles adapted to habits and contexts are prone to change based on certain personal values,
M
perception and information (environmental and knowledge value), influence of social context like
D
image, acceptance, peer group identity (social value) and opportunity like availability of alternatives
TE
The endeavour to understand the sustainable consumption behaviour has become ubiquitous among
EP
the academic groups in the recent years (Wang et.al, 2013). Many models have been developed to
explain sustainable consumption behaviour or green consumption behaviour (Wang et.al, 2013;
C
Zhao et.al, 2013). Sustainable consumption behaviour has been studied in various economies to
AC
access general pro-environmental behaviour, green consumption behaviour (Wang et.al, 2013; Zhao
et.al, 2013), household recycling, waste management behaviour (Barr et.al, 2005) and domestic
PT
Functional value is measured by consumers’ perception about the product performance as durability,
RI
permanence, dependability, reliability, price and quality. It is assessed as the primary driver of
consumer choice behaviour in green product purchase decision (Sheth et. al, 1991; Bei and Simpson,
SC
1995). However, in case of high priced products, they might opt for other criteria apart from price
for product selection. Beverage consumers in Germany exhibit eco-friendly behaviour although not
U
ready to compromise with price and taste for environmentally compatible packaging (Van et.al.
AN
2009). Higher income group of Taiwanese consumers are likely to pay higher premium, perceiving
M
green products to have superior quality (Tsay, 2010). Consumers’ extreme price sensitivity for green
purchase doesn’t exhibit much environmental responsibility (Malhotra and Maheshwari, 2011).
D
Eventually there has been escalation in number of consumers in developed countries who are taking
TE
substantive steps to reduce environmental degradation and are amenable to pay premium for green
goods (Laroche et al,.2001; Eriksson, 2004; Lung, 2010).Given these arguments, the following
EP
Social value measures perceived utility derived from association with one or more social groups.
Social pressure is a key driving force behind consumer choice (Sheth at al., 1991; Bei and Simpson,
1995). Environmental behaviours are inspired by sense of social responsibility. However, several
ACCEPTED MANUSCRIPT
studies suggest that consumers’ decisions are influenced more by personal factors like attitude and
personality traits rather than social norms or pressure (Shamdasani et al., 1993).Based on this
PT
Hypothesis 2: sustainable consumption behaviour is positively influenced by social value.
RI
Conditional value denotes utility derived in a specific situation. Consumer research recognizes that
SC
changes in consumer situational variables may affect green product adoption (Ottaman, 1998;
Saxena and Khandelwal, 2010; Niemeyer, 2010; Gadenne et al., 2011). This study proposes the
hypothesis below.
U
AN
Hypothesis 3: sustainable consumption behaviour is positively influenced by conditional value.
M
Environmental value concerns the relatively stable notions about the issues such as limit of the
TE
population that earth is reaching, relationship between environment and development. With increase
in protective feeling towards the environment, consumers change their consumption pattern and go
EP
green (Choi and Kim, 2005; Kilbourne and Pickett, 2008). Recent studies have found that those with
higher NEP scores (New Environmental Paradigm) are most likely to engage in pro-environmental
C
behaviour (Wang et.al, 2013). Individual’s emotions exhibited towards environmental protection and
AC
enhancement of individual responsibility will trigger green purchase decisions (Liu et al., 2010; Rex
Knowledge value concerns the perceived utility derived to satisfy the want of knowledge and
seeking novelty (Laroche et al., 2001).Consumer inclinations to satisfy a desire for knowledge
PT
regarding the product attributes and novelty have favourable impact on consumer behaviour towards
buying green products(Tanner and Kast, 2003). Lack of information about green products often
RI
results in an attitude behaviour gap between consumer environmental concern and actual buying
SC
behaviour (Ginsberg and Bloom, 2004). Thus availability of information may fill the gap. Therefore,
U
Hypothesis 5: sustainable consumption behaviour is positively influenced by knowledge value.
AN
3. Methodology
M
The survey instrument used for collecting information is segmented into three sections: consumers’
TE
consumer choice behaviour for products with green credential and products without green credential.
EP
A five-point Likert scale was used on the instrument. The scale ranged from 1 to 5, indicating
[1]=Very Low, [2]= Low, [3]=Medium, [4]=High and [5]= Very High, where ‘1’ stands for strong
C
disagreement and ‘5’ represents strong agreement (Lin and Huang, 2012; Wang et.al, 2013).The
AC
five items in the questionnaire measuring sustainable consumption behaviour scale (Wang. et. al,
2013) and nineteen items to measure the five consumption values scale (Lin and Huang, 2012) were
duly adapted and modified as per the requirements. The instrument was tested and validated.
ACCEPTED MANUSCRIPT
The study tries to prognosticate the leverage of consumption values on sustainable consumption
behaviour (SCB) in the context of the emerging economies with respect to two consumer segments
PT
experiencing differential green choice behaviour namely choice preference for products with green
credential’ (CPWGC) and those with ‘choice preference for products without green credential’
RI
(CPWOGC). Stratified random sampling technique was applied for data collection and analysis. A
SC
structured questionnaire was distributed to 600 consumers at different workshops and conferences on
research and environmental awareness held at two different central universities in India between
U
May, 2013 and July, 2013 exhibiting a valid response of 89 per cent. Of the total valid responses, 53
AN
per cent was the segment with preferential approach for products with green credential and the rest
47 per cent had either no prior green purchase or consumption experience or had inhibitions for the
M
same for future. One-way ANOVA was applied to determine whether consumption values differ
significantly across groups with different levels of choice behaviour products with or without green
D
credentials. Multiple linear regressions were applied for evaluation of the factors that prognosticate
TE
Consumers were classified into two groups- those with ‘choice preference for products with green
C
credential’ (CPWGC) and those with ‘choice preference for products without green credential’
AC
Before testing the hypotheses, reliability tests were conducted for each variable (Table 2). Results
show the reliability statistics vary from 0.67 to 0.89 and reliability of the questionnaire has been
PT
substantiated (Landis and Koch, 1977).
3.5. Regression analysis for consumers’ with choice preference for products without green
RI
credential
SC
For the multiple regression analysis, sustainable consumption behaviour for the segment the
exhibiting choice preference for products without green credential was modelled as the dependent
U
variable and respectable consumption values as the predictor variables (Table 3). Only two variables
AN
are entered in the model with conditional value explaining 23 per cent variance and functional value
M
In multiple regression analysis, sustainable consumption behaviour of the segment exhibiting choice
EP
preference for products with green credential and representing 47 per cent of the sample population
was modelled as the dependent variable whereas the corresponding consumption values were
C
modelled as the predictor variables (Table 4). As indicated by the regression for sustainable
AC
consumption, the first predictor to enter the model is social value, explaining a variance of 50 per
cent. Model entry for the other variables has the following order: knowledge value (0.16),
environmental value (0.01), conditional value (0.01) and functional value (0.01). The numbers in the
parenthesis indicate incremental gain in R2 where the consumption values are significant (p <0.05).
ACCEPTED MANUSCRIPT
The ordering of the model entry suggests social and knowledge value are more effective in
PT
All the five consumption value scales (Functional, Social, Conditional, Environmental and
Knowledge) are positively and significantly correlated with each other (p<0.01) (Table 5). The

observed highest coefficient is 0.80 and exists between knowledge value and conditional value.

4.3. Effects of consumption values on sustainable consumption behaviour
M
The sustainable consumption behaviour was measured based on a function of all the consumption
values for both the segments comprising of 534 respondents (Table 6). The four variables entered in
D
the model with knowledge value explaining 32.7per cent variance, followed by environmental value
TE
(4.2%), conditional value (1.9%) and functional value (0.8%). The Variance Inflation Factor (VIF)
in the co-linearity statistics being less than 5 for all the predictor variables indicates absence of
EP
multi-collinearity problem.
C
One way Analysis of Variance was performed with the two consumer segments as independent
variable and functional, social, environmental, conditional and knowledge values as dependent
variables. Analysis (positive p-value less than 0.05) suggests that consumption values regarding
sustainable consumption differ significantly across the groups exhibiting differential preferential
approach for products with or without green credential. Consumers with ‘choice preference for
ACCEPTED MANUSCRIPT
products with green credential’ (CPWGC) tend to have stronger significant concurrence with all the
five consumption values than those with ‘choice preference for products without green credential’
PT
In this study, ‘CPWGC’ consists of consumers’ with green purchase habits or experience or who
consider products’ environmental impact as one of the major evaluative parameters for both nominal
RI
and extended purchase involvement. Based on large scale questionnaire survey of two consumer
SC
segments, sway of consumption values on sustainable consumption behaviour in the context of a
developing economy has been described. Analysis of variance (Table 7) indicates the level of
U
consumption values for the consumers with green choice preference are significantly higher than
AN
those with no such favour.
Considerable variation is observed to exist between the two groups with regard to their consumption
M
values with ‘knowledge value’ (4.17) being the highest for the consumers’ exhibiting a preferential
approach towards green products and inquisition to acquire sufficient cognizance about product life-
D
cycle before making purchase decisions. The high ‘conditional value’ (3.03) for the other cluster
TE
reinforces the importance of contingent factors like financial incentives in their purchase
decisions.The functional value, social, conditional, knowledge and epistemic value register

decision (Table 4). Social norms, peer group cohesiveness, want of admiration appreciate consumers
AC
with choice preference for green credential products, to adopt sustainable consumption practices
(0.39). Knowledge perception and environmental labelling or disclosures for products (0.36) with
approbatory perception towards environmental protection and society raise the environmental value
benefits on products credit sustainable consumption (0.17). Consumers prefer products with green
ACCEPTED MANUSCRIPT
credential having assurance about the quality standards, price, ingredients and resultant benefits from
usage of green products (0.11). The leveraging impact of knowledge value thus necessitates
Although social value was found to be the most important adjudicating factor for the green
PT
credential favouring segment, since it seems to influence the other segments’ sustainable
RI
consumption behaviour, its influence on the overall consumers’ sustainable consumption behaviour
is insignificant. Both the segments tend to prioritize on the functional and contingent aspects, thus
SC
the non-green credential preferring segment abstains from green purchase owing to price sensitivity.
The detailed analysis of sustainable consumption behaviour (SCB) clearly shows that knowledge
U
value, environmental concern and want of social prestige do not influence the non-green cluster. The
AN
low explanatory power of the consumption values for the CPWOGC shows external moderators like
SCB.
D
Individuals’ segments with non-preferential approach for products with green credentials are
TE
apprehensive neither about the environmental disclosures nor on product labeling about its life-
cycle. Despite inhibitions for green purchase pertaining to price which is often considered exorbitant
EP
and unjustified (reducing the consumers’ surplus), this non-preferential consumer segment may be
considered as potential segment of future green buyers based on the favourable functional value. The
C
cumulative adjusted R2 (0.25) suggests that apart from the consumption values there are other
AC
parameters which aid to evaluate the sustainable consumption behaviour for individuals without any
Knowledge and environmental values are important determinant of sustainable consumption because
it may not only facilitate understanding of environmental issues through want of enhanced product
ACCEPTED MANUSCRIPT
of individual realization of responsibility for the environment. For the predicting variables, influence
of conditional and functional values are ubiquitous across both the segments irrespective of their
choice preferences thus highlighting the price sensitivity concerns among the consumers in a
PT
developing market which may relate to constraints in the expansion of green product market.
RI
Improvement in green consumption can be achieved through integrating efforts of governments and
related industrial sectors advocating sustainable environmental awareness and protection. Awareness
SC
campaigns about unprecedented environmental problems by social organizations, governments and
corporate sectors can even inculcate morale and value norms among the less educated, highly price-
U
sensitive segment, thereby arousing their environmental conscience so that they can tilt their
AN
sustainable consumption behaviour towards the green products and play a critical role towards
sustainable development. All-directional publicity system may be used based on TV programs for
M
the spread of environmental value, television being the most important medium of entertainment in
D
Studies conducted in European countries, like Greece, Netherlands, Britain reveal that the
environmental awareness and green business policy is the aftermath of consumers’ environmental
EP
awareness (Boztepe, 2012). A substantial portion of the British citizens rated the environment as an
immediate and urgent problem (Dembkowski and Hanmer-Lloyd, 1994), while results of survey
C
revealed British adult consumers’ preference for products with green credential and willingness to
AC
pay premium for the same (Prothero, 1990). With green market alert, the USA market has noticed
unprecedented rise in consumption of products with green credential (Van Liere and Dunlap, 1980;
5. Conclusions
The study successfully explains consumers’ motivation to adopt sustainable consumption behaviour.
On the consumer segment with preferential approach for products with green credential, the
strongest influence behind sustainable consumption behaviour (SCB) comes from peer opinion and
PT
social recognition. Positive word-of-mouth and socio-cultural practices also play the role of
RI
significant motivators. Marketers producing products with or without green credential should adopt
effective mechanisms like under-promise and over-delivery, follow-up to reduce consumers’ post-
SC
purchase dissonance to prevent spread of negative word-of-mouth thereby hindering sustainable
U
more participatory education approach should be promoted for accurate understanding of the
AN
environmental knowledge. Manufacturers should try to offer products with sufficient product
information on its environmental consequences, compliances and after life disposal. Eco-labeling on
M
products will raise the knowledge value for the green preferential segment and subsequent
D
sustainable consumption behaviour adoption. The line of difference between the green preferential
TE
and non-green preferential segments may be shrug off by effective elevation of functional and
conditional values, as both being significant prognosticating factors for sustainable consumption
EP
behaviour across choice preference category. Taking into consideration the individual’s price
sensitivity, discounts or subsidies can be offered on green products for boosting their conditional
C
value. Institutional restructuring for creation of economic incentives for environmentally compatible
AC
production practices would be effective coupled with educational drivers for promotion of products
adding value to the environment. This will eventually influence willingness to purchase analogous
products even for the non-preferential consumer segment. The policy makers should enhance overall
practices (Kaiser and Gutscher, 2003; Barr et.al, 2005; Gadenne et. al., 2011). Effective
PT
can enhance the environmental value among the non-green product preferential segment, thus adding
RI
one variable in prognosticating their sustainable consumption behaviour.
Finally, coherent sustainable consumption policies across the government departments are needed
SC
irrespective of spread of green awareness among consumers. Governments should also offer
subsidies and supportive policies to boost industrial sectors in effective promotion of green products
U
thereby tilting the preference of the non-green preferential segment towards the green products
AN
subject to bargain-basement in green product pricing. However, due emphasis should not only be
given on sustainable consumption behaviour and green consumption but also on the post-
M
consumption phase of after-life disposal of products. Sustainable consumption behaviour should thus
D
keep. Consumption values channelize their sustainable consumption although the type of product to
discounts or subsidies on products tends to have the highest influence among both the groups,
significantly high for the green credential preferring segment than those without similar preference.
