Sustainable consumption: the effects of knowledge,cultural values,environmental advertising,and demographics

As a result of human lifestyles and unsustainable consumption patterns, the environment continues to deteriorate and thus inhibit sustainable development. In order to curb this situation and promote a sustainable economy, one of the solution is to reduce conventional products consumption and shift to green products. Over the past 20 years, marketing managers keenly seek to understand the green market; however, inadequate information on how to promote consumers’ green behavioral intentions is slowing the growth of green markets and becomes a barrier for firms when developing segments and communicating strategies for effective promotion of green products in countries like Malaysia where the trend is fairly new. Therefore, this study attempts to examine the impact of environmental knowledge, cultural values, and environmental advertising and determine the moderating effect of income level, education level, and gender on consumers’ green purchase intentions. A survey was administered, and a total of 405 valid questionnaires were obtained. Structural equation modeling technique was used to evaluate the causal model by using SmartPLS 2.0 software. The finding results suggest that cultural values and environmental advertising are the main influences in building green purchase intentions, while environmental knowledge is not significantly related. The results also indicate that education level and gender have a significant positive moderation effect while income did not. This suggests that green purchase intentions’ motivational factors are greater among highly educated individuals, with females in particular. The discussions and implications of these findings are further elaborated.

Green markets, eco-certification, and equilibrium fraud

Consumers voluntarily pay significant price premiums to acquire unobservable environmental attributes in green markets. This paper considers the performance of eco-certification policy under circumstances where consumers cannot discern environmental attributes in goods, but are able to form rational expectations regarding the extent of illicit activities in the green market. The main results are: (i) fraud is less prevalent in green markets when entry barriers limit the number of firms; (ii) conventional environmental policies on polluting techniques increase the incidence of fraud, and can even preclude the use of non-polluting techniques which would otherwise emerge in green markets; (iii) voluntary eco-certification policies can decrease fraud, increase output, and raise profits per firm; and (iv) in cases where the socially optimal resource allocation can be supported, the optimal policy involves negative unit certification fees, positive fixed certification fees and is revenue-generating for the certifying agent.     

Biomass fuel use,burning technique and reasons for the denial of improved cooking stoves by Forest User Groups of Rema-Kalenga Wildlife Sanctuary,Bangladesh

ABSTRACT

This study investigates the structural linkages of product quality, corporate image, store image, and price on customer satisfaction and loyalty towards green products usage in Malaysia. The research used structural equation modelling technique via AMOS 21.0 computer program for data analysis across a sample of 200 university students who applies a green lifestyle, such as purchasing green products which are referring to only retail goods, using recyclable products, and ozone-free products. Empirical analysis divulged that product quality followed by corporate image, store image, and product price jointly affected customer satisfaction in using green products. They are highly concerned that the green store provides a variety of good quality products with good value for money. Marketers should aggressively promote the identification of green products and overcome the problem of just noticeable difference between green product and non-green product among consumers for business sustainability. Empirical findings provide valuable insights to put forth in outlining effective marketing strategies that widen the marketers’ understanding of consumer behaviour in using green products with regard to their satisfaction and loyalty levels from the perspective of product quality, corporate image, store image, and product prices in Malaysia markets.     

Can household consumers save the wild fish? Lessons from a sustainable seafood advisory

Conservation organizations seeking to reduce over-fishing and promote better fishing practices have increasingly turned to market-based mechanisms such as environmental sustainability labels (eco-labels) in order to shift patterns of household consumption. This paper presents an analysis of consumer response to an advisory for sustainable seafood adopted by a regional supermarket in the United States. The advisory consisted of a label in which one of three traffic light colors was placed on each fresh seafood product to inform consumers about its relative environmental sustainability. Green meant “best” choice, yellow meant “proceed with caution,” and red meant “worst choice”. Using a unique product-level panel scanner data set of weekly sales and taking advantage of the random phase-in of the advisory by the retailer, we apply a difference-in-differences identification strategy to estimate the effect of the advisory on overall seafood sales as well as the heterogeneous impact of the advisory by label color and whether the seafood met additional health-related criteria. We find evidence that the advisory led to a statistically significant 15.3% decline in overall seafood sales, a statistically significant 34.9% decline in the sale of yellow labeled seafood, and a statistically significant 41.3% decline in the sale of yellow labeled seafood on a mercury safe list. We find no statistically significant difference in sales of green or red labeled seafood.     

Saving power to conserve your reputation? The effectiveness of private versus public information

Environmental damage is often an unseen byproduct of other activities. Disclosing environmental impact privately to consumers can reduce the costs and/or increase the moral benefits of conservation behaviors, while publicly disclosing such information can provide an additional motivation for conservation - cultivating a green reputation. In a unique field experiment in the residence halls at the University of California – Los Angeles, we test the efficacy of detailed private and public information on electricity conservation. Private information was given through real-time appliance level feedback and social norms over usage, and public information was given through a publicly visible conservation rating. Our analysis is based on 7,120 daily observations about energy use from heating and cooling, lights and plug load for 66 rooms collected over an academic year. Our results suggest that while private information alone was ineffective, public information combined with private information motivated a 20 percent reduction in electricity consumption achieved through lower use of heating and cooling. Public information was particularly effective for above median energy users.     

Life cycle assessment for printed newspapers in Northwestern Mexico

This paper aims to present the relevant results of a Life Cycle Assessment (LCA) study conducted on printed matter under a sheet-fed offset printing process by a company located in northwestern Mexico. Different scenarios were simulated in order to support decisions related to the improvement of environmental performance along the production processes. The study design was based on the European Platform on Life Cycle Assessment (EPLCA), which is in line with the ISO 14040 and 14044:2006 standards on LCA. The scope of the study was cradle-to-gate, with emphasis on the production of printed matter. The method chosen for the impact assessment was Impact 2002+ with a combined midpoint–damage approach. The results of the study showed that the major contributors to adverse effects were, primarily electricity consumption followed by paper consumption during the printing operation, as well as consumption of ink to a small degree. As for the plate-making operation along with the generation of secondary products, the result was negative. This is essentially due to involvement of recyclable materials, thus contributing to the prevention of raw material extraction. The smallest impact was observed from processes involving cleaning products and LP gas. The main issues of concern stemming from the results are electricity consumption and printing – both activities dominate almost all the midpoint categories. Generation of secondary products also had a relative environmental impact along the supply chain. Cleaning agents and LP gas did not have a significant impact on the final results of the process.     

Durable goods and long-run electricity demand: Evidence from air conditioner purchase behavior

I estimate a dynamic structural model of demand for air conditioners, the most energy-intensive home appliance in the US. The model explores the links between demand for durable goods and expected changes in key attributes: energy efficiency and price. I incorporate expectations explicitly as a feature of the choice setting, and use parameter estimates from the model to calculate durable good demand elasticities with respect to energy efficiency, electricity price, and price of the durable itself. These estimates fill a large gap in the literature, and also shed light on consumer behavior in this setting. Results indicate that consumers are forward-looking and value the stream of future savings derived from energy efficiency.     

Book reviews and notices

This study aims to examine the mediating role of the customer environmental satisfaction in the effect of environmental friendliness of products and the company on customer loyalty in using green products in Malaysia. Structural equation modeling (SEM) analysis is performed to test the proposed hypotheses among 200 full time university students with purchasing experience at least once a week green products like organic vegetables. SEM results showed that customer environmental satisfaction significantly affected customer loyalty. This pair of relationships has the highest standardized beta coefficients, signifying the most important aspect of consideration by respondents among the rest of the proposed hypotheses. Next, customer environmental satisfaction partially mediated the relationship between environmental friendliness of products and customer loyalty in using green products. The results confirmed that customers are satisfied with their decision to purchase green products as they consume the least amount of resources and energy which results in minimum environmental damage and are also easy to recycle, disassemble, decompose, and reuse. Marketers should focus on creating effective marketing strategies and green promotional activities to attract customers for their green products. Marketers should control and enhance the quality of green products, as well as emphasizing their environmental satisfaction and increasing customer loyalty levels. This empirical study advanced marketers’ and policy makers’ understanding of the identification of customer environmental satisfaction as a mediator in the relationship between environmental friendliness of products and customer loyalty has been inspected in Malaysian context.     

Use of DNA barcoding to reveal species composition of convenience seafood

Increased education of consumers can be an effective tool for conservation of commercially harvested marine species when product labeling is accurate and allows an informed choice. However, generic labeling (e.g., as white fish or surimi) and mislabeling of seafood prevents this and may erode consumer confidence in seafood product labels in general. We used DNA barcoding to identify the species composition of two types of convenience seafood (i.e., products processed for ease of consumption): fish fingers (long pieces of fish covered with bread crumbs or batter, n = 241) and seafood sticks (long pieces of cooked fish, n = 30). In products labeled as either white fish or surimi, four teleost species were present. Less than 1.5% of fish fingers with species-specific information were mislabeled. Results of other studies show substantially more mislabeling (e.g., >25%) of teleost products, which likely reflects the lower economic gains associated with mislabeling of convenience seafood compared with whole fillets. In addition to species identification, seafood product labels should be required to contain information about, for example, harvesting practices, and our data indicate that consumers can have reasonable confidence in the accuracy of the labels of convenience seafood and thus select brands on the basis of information about current fisheries practice.     

Factors for implementing end-of-life product reverse logistics in the Chinese manufacturing sector

Dedicated, skilled and relatively cheap manpower coupled with efficient manufacturing techniques has elevated China’s status as the world’s factory. China is now capable of producing virtually any product, from cheap toys to some of the most sophisticated goods and equipment. The resultant economic benefits and associated enormous consumption due to rise in per capita income are accompanied by an equally unprecedented negative environmental impact arising from the huge increase of end-of-life (EoL) products. This study aims to understand and prioritise EoL product reverse logistics (RL) factors from Chinese manufacturing sector perspective. Multiple case studies in five different industries within the manufacturing sector have been carried out and analytic hierarchy process (AHP) has been employed to prioritise the governing factors for the successful RL implementation in the Chinese manufacturing sector. Results indicate that Chinese firms are unlikely to embark on RL operations without external factors such as strict government legislation.     

Accessibility and trust: the two dimensions of consumers’ perception on sustainable purchase intention

The aim of this article is to shed new light on which dimensions compose sustainable purchase intention (SPI) with the purpose of understanding what moves consumers to a potentially more sustainable behaviour. Even though several studies have researched which factors influence consumer’s intention to buy in a more sustainable way, no comparable research in consumer behaviour was found studying these dimensions in a triple bottom line perspective (profit, people, and planet) that could also provide future corporate and academic applications. Therefore, this article proposes a new construct – Consumers’ Perception on SPI, defined using the C-OAR-SE procedure and measured using exploratory and confirmatory factor analysis using two different samples. In-depth interviews and online survey to actual consumers of sustainable products were undertaken in partnership with a sustainable project using its database, guaranteeing that real consumers’ perceptions were gathered for this study. The construct is proposed with two dimensions (measured by nine items): Accessibility (including facets such as product lower pricing, availability in stores, and being sold within a convenient proximity to home) and Trust (including consumers needs such as: to get to know and trust products through understanding the labels; to have had good experiences in the past or simply to have new trial opportunities). Theoretical and practical implications of the findings are also discussed.     

Do energy prices influence investment in energy efficiency? Evidence from energy star appliances

I examine whether electricity prices influence the likelihood that consumers purchase high efficiency appliances by using state-year panel data on electricity prices and the proportion of sales of new appliances that involve high efficiency “Energy Star” models. I find no evidence that electricity prices affect the propensity for consumers to choose high efficiency appliances. Point estimates are extremely small and precisely estimated. The findings suggest that price-based energy policies may be limited in the extent to which they increase investment in residential energy efficiency, which has been considered one of the lowest cost opportunities for reducing carbon emissions.     

Interested consumers’ awareness of harmful chemicals in everyday products

Background

Everyday products can contain a multitude of harmful substances unnoticed by most consumers, because established risk communication channels reach only part of the society. The question is, whether at least interested and informed consumers are able to use risk communication tools and assess harmful chemicals in products.

Results

An online survey investigated the awareness of 1030 consumers on harmful substances in everyday items. Participating consumers’ education level, knowledge in chemistry, and motivation were above society’s average. Although a large number of responses showed that survey participants were familiar with several aspects of the issue, the results revealed that knowledge in chemistry helped, but was not enough. Many participants assumed that products with an eco-label, natural personal care products, products without hazard pictograms or products produced in the European Union would not contain harmful substances. Most participants indicated to use hazard pictograms, information on the packaging, reports in the media, and environmental and consumer organizations as information sources, while information by authorities and manufacturers were not named frequently and did not receive high confidence. Smartphone applications were not indicated by many participants as information sources. The information sources most trusted were environmental and consumer organizations, hazard pictograms, and lists of ingredients on the containers. The declared confidence in certain risk communication instruments did not always correspond to the use frequencies indicated. Nearly all participants considered legislators as responsible for the reduction of harmful substances in consumer products.

Conclusions

Misconceptions about harmful substances in products can be dangerous for the personal health and the environment. The survey indicates that motivation, educational level, and chemical expertise do not automatically provide an appropriate understanding of harmful substances in products. If well-informed consumers are not sufficiently capable to use risk information elements as revealed in this study, then this will be even more the case for the general public. Consumer awareness should be stipulated by an improved information strategy about chemical risks in consumer products with an extensive participation of the target groups and by more efforts by authorities and manufactures to build trust and to provide easily understandable information.

     

Green,greener, greenest: Eco-label gradation and competition

This paper analyzes two common features of markets in which eco-label programs certify that products are “green”: gradation—single programs offering multiple certification standards (e.g., platinum, gold, silver)—and competition—multiple programs vying to certify to their respective standards. We find that, depending on whether programs are sponsored by industry, environmental groups, or a government, they have strikingly different incentives to grade or compete. Industry sponsors are indifferent about both; environmentalist sponsors optimally grade or compete with other environmentalist sponsors only if consumer preferences for green consumption are skewed in a specific way; and government sponsors׳ decisions depend on the relative importance of private vs. public benefits generated by the green market. We find also that it is no accident that green markets frequently have an environmentalist program competing with an industry one. For each of the cases examined, our analysis is consistent with casual empirical evidence.     

Government green procurement spillovers: Evidence from municipal building policies in California

We study how government green procurement policies influence private-sector demand for similar products. Specifically, we measure the impact of municipal policies requiring governments to construct green buildings on private-sector adoption of the US Green Building Council?s Leadership in Energy and Environmental Design (LEED) standard. Using matching methods, panel data, and instrumental variables, we find that government procurement rules produce spillover effects that stimulate both private-sector adoption of the LEED standard and investments in green building expertise by local suppliers. These findings suggest that government procurement policies can accelerate the diffusion of new environmental standards that require coordinated complementary investments by various types of private adopter.     

Umwelteigenschaften von Produkten Die Rolle der Ökobilanz in ISO Typ III Umweltdeklarationen

Goal and Scope

Type III Environmental declarations (Environmental product declarations, EPD) are intended to inform interested parties about the environmental performance characteristics of products. They are based mainly on LCA according to ISO 14040ff, provide its results as inventory or impact category indicators and thus describe the product system under investigation. ISO 14025 is out for ballot as FDIS. The concept of EPD has found a market in particular in the construction sector. It has a considerable part in the European Integrated Product Policy, e.g. documentation of improvement in design for environment, documentation of compliance with green procurement requirements.

Main Features

EPD are a means to communicate the results of a LCA-study according to ISO 14040ff in a comparable and harmonised way. ISO (FDIS) 14025 describes how to develop and document consistent and comparable data sets. This report exemplifies three levels in the development of EPD for which the standard provides requirements. 1. Framework for the development of an EPD program including verification procedures for EPD. 2. Defining the rules for conducting the LCA according to ISO 14040ff as well as additional information for defined product categories (product category rules). 3. Development and documentation of EPD according to the PCR.

Results and Conclusions

After quite a few years of standardisation work the new standard ISO (FDIS) 14025 will provide a systematic approach to documenting and communicating LCA results in an EPD. This will support propagating LCA from its academic origin to a practical tool for the assessment of the environmental performance of a product system. An essential part will be the participation of LCA experts in EPD programs.

Recommendations and Outlook

An enormous effort for developing appropriate conventions will have to be taken by all interested parties to come up with consistent and comparable EPD in different branches. In some areas defining such conventions has been shown to be possible. An important part is the development of quality criteria for modelling as well as for the databases used to calculate the LCA. To find sufficient credibility at economically acceptable conditions with a minimum of bureaucratic effort more practical experience will have to be gained. This holds especially for the trust in the EPD results based on the independence of the review, transparency of procedures and the participation of interested parties. There is a demand on education for SME developing EPD for their products as well as for the users of EPD on how to document EPD transparently and apply them properly.     

Understanding why consumers in China switch between wild,farmed, and synthetic bear bile products

An important rationale for legally farmed and synthetic wildlife products is that they reduce illegal, wild-sourced trade by supplying markets with sustainable alternatives. For this to work, more established illegal-product consumers must switch to legal alternatives than new legal-product consumers switch to illegal wild products. Despite the widespread debate on the magnitude and direction of switching, studies among actual consumers are lacking. We used an anonymous online survey of 1421 traditional Chinese medicine consumers in China to investigate switching among legal farmed, synthetic, and illegal wild bear bile. We examined the past consumption behavior, applied a discrete choice experiment framed within worsening hypothetical disease scenarios, and used latent class models to investigate groups with shared preferences. Bear bile consumers (86% respondents) were wealthier, more likely to have family who consumed bile, and less knowledgeable about bile treatments than nonconsumers. Consumer preferences were heterogenous, but most consumer preferences switched between bile types as disease worsened. We identified five distinct latent classes within our sample: law-abiding consumers (34% respondents), who prefer legal products and were unlikely to switch; two all-natural consumer groups (53%), who dislike synthetics but may switch between farmed and wild; and two nonconsumer groups (12%), who prefer not to buy bile. People with past experience of bile consumption had different preferences than those without. Willingness to switch to wild products was related to believing they were legal, although the likelihood of switching was mediated by preferences for cheaper products sold in legal, familiar places. We found that consumers of wild bile may switch to legal alternatives, given the availability of a range of products, whereas legal-product consumers may switch to illegal products if the barriers to doing so are small. Understanding preferences that promote or impede switching should be a key consideration when attempting to predict consumer behavior in complex wildlife markets.     

Teil II: Die Energiebilanz der Universität Osnabrück

One central aspect of the environmental management system for universities developed in Osnabrück is the environmental audit of universities as realized by an ecobalance. This article deals with modelling of the material and energy flows caused by the energy supply of the University in Osnabrück using the software Umberto^®. The result is the university’s energy balance. 37% of the primary energy gets lost in the pre-processes of energy production, mainly during electricity generation. The final energy consumption of the university can be split into 37% electricity and 63% heat, whereas the relation of CO₂ emissions is almost the opposite. Related to this area, the electricity consumption in the different buildings is partially above that seen in similar university buildings in Germany, but below that of all the other values observed for universities located in Lower Saxony. Both the electricity and heat consumption, and therefore also the climate-damaging emissions of CO₂, have increased over the past years. Without further measures the university will not be able to achieve the CO₂-reduction target of the federal government. Recommended are the increased use of district heating power stations to produce the university’s own electricity with lower emissions and energy saving measures, especially in the field of electricity which is responsible for high CO₂-emissions.     

Understanding implications of consumer behavior for wildlife farming and sustainable wildlife trade

Unsustainable wildlife trade affects biodiversity and the livelihoods of communities dependent upon those resources. Wildlife farming has been proposed to promote sustainable trade, but characterizing markets and understanding consumer behavior remain neglected but essential steps in the design and evaluation of such operations. We used sea turtle trade in the Cayman Islands, where turtles have been farm raised for human consumption for almost 50 years, as a case study to explore consumer preferences toward wild‐sourced (illegal) and farmed (legal) products and potential conservation implications. Combining methods innovatively (including indirect questioning and choice experiments), we conducted a nationwide trade assessment through in‐person interviews from September to December 2014. Households were randomly selected using disproportionate stratified sampling, and responses were weighted based on district population size. We approached 597 individuals, of which 37 (6.2%) refused to participate. Although 30% of households had consumed turtle in the previous 12 months, the purchase and consumption of wild products was rare (e.g., 64–742 resident households consumed wild turtle meat [i.e., 0.3–3.5% of households] but represented a large threat to wild turtles in the area due to their reduced populations). Differences among groups of consumers were marked, as identified through choice experiments, and price and source of product played important roles in their decisions. Despite the long‐term practice of farming turtles, 13.5% of consumers showed a strong preference for wild products, which demonstrates the limitations of wildlife farming as a single tool for sustainable wildlife trade. By using a combination of indirect questioning, choice experiments, and sales data to investigate demand for wildlife products, we obtained insights about consumer behavior that can be used to develop conservation‐demand‐focused initiatives. Lack of data from long‐term social–ecological assessments hinders the evaluation of and learning from wildlife farming. This information is key to understanding under which conditions different interventions (e.g., bans, wildlife farming, social marketing) are likely to succeed.
