This research examines how the design of the online energy label can be improved to stimulate consumer choice of energy-efficient household products in Web stores. Based on general evaluability theory, the authors propose new label formats that aim to improve the evaluability of the label information for consumers and test their influence during two distinct stages in the online decision-making process: consideration set formation and final choice.

Two large-scale controlled online experiments are conducted with over 10,000 consumers in 10 European countries. The experiments test label alternatives in simulated online store environments, mimicking the two distinct decision stages, for four product categories to enhance generalizability. The data are analyzed using random-intercept linear and logistic regression models to account for their multi-level structure.

The results show that the impact of the online energy label on consumers’ online decision-making depends on both the label format and the decision stage (consideration vs choice), but in a different way than expected. The findings reveal that the current online energy label is significantly outperformed by a label that provides reference information by incorporating the scale range. This alternative label is particularly effective in the consideration set formation stage, and among consumers who consider energy efficiency a relatively unimportant choice criterion.

Online energy labels encourage consumers to consider and choose more energy-efficient products, especially if scale range information is included. The present results stress the importance of presenting this information early on in the online decision process. They also show that, particularly at this early stage and particularly for consumers who find energy efficiency a relatively unimportant choice criterion, label format matters.

The present findings provide important input for policymakers in the context of the ongoing revision of the EU energy label. They also help online retailers make decisions about when and how to present product information on their websites.

This study contributes to the literature on product labelling by examining the effects of relatively unexplored types of reference information in two distinct stages of the consumer decision-making process. To the best of the authors’ knowledge, this study is the first to test the effectiveness of the online energy label.

This study examines how consumption values influence consumers' purchase intention of energy-efficient home appliances in South Africa, an emerging market. The study further investigates the mediating role of consumers' attention to energy-efficient labels affixed on home appliances while making a purchase decision and the moderating effect of consumer trust in the environmental claims.

Using a quantitative approach, this study relied on self-administered questionnaires to collect data from 505 household representatives in South Africa's Gauteng Province. The proposed conceptual model was empirically tested using structural equation modelling, moderation and mediation analyses.

The results revealed that economic, emotional and social values can only influence consumers' intention to purchase energy-efficient appliances if consumers pay attention to the energy-efficiency label affixed on the appliance. Functional value, however, has a significant direct impact on purchase intention. Moreover, the results indicate that trust in energy-efficiency labels strengthens the effect of functional and emotional values on consumers' attention to energy-efficiency labels.

Findings of this study highlight the importance of capturing the attention of consumers to energy-efficiency labels during the buying process as well as increasing their trust in those labels. Results indicate that consumers are more attracted to the functional and social values that energy-efficient appliances provide. This study is of particular interest to policymakers, retailers and manufacturers, as it sheds light on key strategies to implement to effectively promote the purchase of energy-efficient household appliances in South Africa.

The key purpose of this paper is to quantify the size of the energy-efficiency gap (EEG) for air conditioners at the household level in Delhi. Most of the studies in the EEG tradition broadly define EEG as the difference between the actual and optimal level of energy efficiency. The optimal level of energy efficiency is defined at the societal level (that weigh social costs against social benefits) and the private level (that weigh private costs against private benefits).

The authors base the empirical results in this study on the basis of the primary data collected through in-person interviews of the high-income urban households in Delhi in 2014-2015. The sample of 101 households was collected through purposive random sampling. The survey data include information on type and number of AC possessed, hours of operations, socioeconomic characteristics and awareness and habits of households.

Using primary data of 101 high-income urban household, the paper finds that average EEG is about 10 per cent of total electricity demand of ACs at the household level. The maximum current saving potential measured as a difference between hypothetical energy consumption, if everyone adopts five star ACs, and actual energy consumption is estimated about 14 per cent of the total electricity demand of ACs. Results from the ordinary least squares regressions demonstrate that individual’s habits, attitude, awareness of energy-efficiency measures and perceptions significantly determine the size of the EEG. Among other things, authors’ empirical analysis shows that information can play a central role in guiding investment in energy-efficient technologies. From the analysis of improving access to understandable information about cost savings, payback period and emission reduction, it is found that full information leads to the significant reduction in the size of the expected private energy-efficiency gap from 10 to 2.98 per cent at the household level.

This paper tests the significance of non-economic and non-social factors in determining the size of the EEG. Apart from socioeconomic factors such as income, occupation and education, individual’s energy-conserving habits and attitudes, awareness of energy-efficiency measures and perceptions are other important factors found to have a significant negative impact on the size of the EEG. This is particularly important for the designing of information programs by policymakers for promoting energy-efficiency choices in view of the change that is required in the behavior and attitudes of the households.

In this study, authors try to estimate the size of the EEG of ACs for the high-income urban households in Delhi. The private energy-efficiency gap estimated at 10 per cent of the household demand for ACs indicates existing saving opportunity for the private households. It is found that provision of comprehensive information about cost savings, payback period and emission reduction reduces the size of the EEG significantly from 10 to 2.72 per cent at the private level. This highlights the existence of limited and incomplete information in the market about the possible costs and benefits of energy-efficiency investments. This paper tests the significance of non-economic and non-social factors in determining the size of the energy-efficiency gap. Apart from socioeconomic factors such as income, occupation and education, individual’s energy-conserving habits and attitudes, awareness of energy-efficiency measures and perceptions are other important factors found to have a significant negative impact on the size of the EEG. This is particularly important for the designing of information programs by policymakers for promoting energy-efficiency choices in view of the change that is required in the behavior and attitudes of the households.

The COVID-19 pandemic has caused a dramatic impact on energy supply and demand. It is vital to understand households’ behaviour with regard to energy, particularly during the pandemic, to deploy future sustainable energy systems. This study aims to investigate the nexus of Malaysian households’ energy consumption behaviour in relation to various electrical appliances, their energy-saving appliance purchasing behaviour and their current possession of energy-saving appliances during the pandemic, especially during the lockdown period, from the perspective of the energy cultures framework.

The partial least squares structural equation modelling technique was used to test hypothesised relationships based on the 1,485 pieces of household data collected using an online and physical survey during the lockdown period in Malaysia.

The energy-saving behaviour cultivated due to the impact of the COVID-19 pandemic led to residential customers’ intentions to purchase energy-saving appliances which subsequently led to their current possession of energy-saving appliances. Indeed, energy-saving behaviours in the kitchen, entertainment, office, home lighting and cooling appliances have more than 77.4% influence on their purchasing behaviour. The consumer’s purchase behaviour for energy-saving appliances has a significant, partially mediating influence on the energy-saving behaviour of various electrical appliances and the consumers’ current possession of energy-saving appliances.

This study could be enhanced by improving the sample using a higher-income group and involving other parts of Malaysia such as the southern region. The findings do extend the energy cultures framework by demonstrating the mediating role of households’ energy-saving appliance purchasing behaviour on the relationship between their energy consumption behaviour in relation to various electrical appliances and their current possession of energy-saving appliances.

The results of this study will help develop future action plans for transitioning to energy-saving appliance practices.

This paper examines the effects of the COVID-19 pandemic on future energy efficiency practices in developing countries from the perspective of the energy cultures framework.

This article looks at the Energy Star showcase dorm room at Tulane University. This project was a model for sustainable living created by a group of students and Tulane's environmental coordinator. The energy and climate change team furnished a dorm room on Tulane's campus with energy‐efficient appliances and electronics, and then gave tours of the room to educate the Tulane community about the potential greenhouse‐gas‐emissions reductions and financial benefits of being smart consumers. One student calculated how much energy the entire campus could save if every resident were to make wise energy choices. By combining education and outreach with a living model, the students were able to inform the entire Tulane community about their efforts and change some bad energy habits.

The purpose of this paper is to investigate the influence of consumers’ collectivism and long-term orientation (LTO) cultural values on their purchase intention in relation to environment-friendly products.

This research adopts a hypo-deductive research design. A unique conceptual model was developed by linking cultural values to key determinants of green purchase behaviour. This model was then tested using a quantitative survey of 682 shoppers in popular Vietnamese electrical appliance stores.

Analysis using structural equation modelling reveals that consumers with greater adherence to collectivism and LTO tend to engage in green purchase behaviour owing to their positive environmental attitudes, strong subjective norms and tolerance of inconvenience associated with eco-friendly product purchase. Gender is found to moderate the relationship between the determinants and purchase intention.

Marketers including manufacturers and policymakers must endeavour (change globally) to reduce or eliminate perceived inconvenience associated with green purchases. They should also effectively communicate messages stressing that eco-friendly product purchases are crucial for environmental protection and benefit consumer groups including family, peers and society in the long-run.

This research is the first of its kind which links consumers’ cultural values at a personal level to all the elements of the theory of planned behaviour. This research also extends current knowledge about green purchase behaviour in emerging markets by focussing on Vietnam.

There is an increasing awareness among manufacturers to make production more sustainable in Southeast Asian countries such as Malaysia and Indonesia. Manufacturers are now urged to not only focus on the business profit but also concern on environment protection by producing green products. However, issues may arise regarding the preferences of customers on green products, which will vary due to the influence of cultural values. This will give an impact on the marketing of green products. The aim of this study is to identify the influence of cultural values on the green products design in Malaysia and Indonesia.

A pretest on the survey instruments was performed to ensure the reliability and validity of the questionnaire. The collected data were statistically analyzed based on the satisfaction level, confirmatory factor analysis and structural equation modeling.

The results showed that customer preferences in Malaysia were mostly influenced by uncertainty avoidance, long-term orientation and power distance, excluding collectivism and masculinity. In Indonesia, the dimension of uncertainty avoidance and long-term orientation had significant influence, whereas power distance, masculinity and collectivism dimension had no influence. Eco-label was identified as the most important factor for green products in Malaysia and having product services characteristics factor for product lifetime extension in Indonesia.

For practices, the cultural values and preferred characteristics identified in this study provide valuable information to policymakers and businesses on what draws customers toward green products in Malaysia and Indonesia. This finding can be used as supported data for the policymakers in order to achieve sustainable development goal (SDGs) in Malaysia and Indonesia.

The findings of this study provide valuable information for designers to design products with green characteristics that cater to the consumer market in Malaysia and Indonesia, as well as other countries which may have similar cultural traits.

The current literature has not investigated the perceived value of energy efficiency by households, regardless of financial benefits. Furthermore, there is a severe lack of research that investigates the effectiveness of the current format of EPC-labels. Therefore, the purpose of this paper is twofold: to study how households value energy efficiency in the housing market, regardless of price effects.

This study uses multiple hedonic regression models to analyse 706,778 Flemish properties for sale or rent between 2019 and 2023. The data is provided by Immoweb – the largest online real estate platform in Belgium. Given that the selling market is driven by different mechanisms than the rental market, the data set was divided in sold (522,164 listings) and rented properties (184,614 listings).

The ambiguous results of the A-label in the selling market indicate that the “class evaluation effect” found in related markets which use labels (e.g. household appliances) is also present in the housing market. However, the results of the other (lower) labels clearly show that owners do value energy improvements within labels, and this effect becomes stronger as the EPC-label becomes better. The rental market shows the opposite results. Energy improvements are only valued if they translate into a financial benefit. Taking these findings into account, the second part of this research shows that rescaling the EPC-label creates an incentive for improvements within labels.

This paper provides novel insights by studying the perceived value of energy efficiency in the absence of financial benefits and critically studying the effectiveness of the EPC-labels in their current shape. By investigating both the sales and rental market, the authors are able to make a comparison which creates valuable insights for academia, governments and real estate professionals.

The purpose of this study is to examine the importance of relationship marketing and particularly customer trust in energy-efficiency labels in social marketing interventions geared towards energy-efficient consumption.

A conceptual model was empirically tested on a sample of 517 users of electronic appliances living in South Africa. The study involved a cross-sectional design, and data were collected via a self-administered survey. Structural equation modelling and mediation analysis were used to test the hypothesised relationships.

The results indicated that customer trust is influenced by customers’ perception of the price and quality of energy-efficiency products, their attitude towards such products and their level of satisfaction with the environmental performance of the products. Customer trust, in turn, showed a positive influence on the customers’ intention to purchase energy-efficiency products and their loyalty to such products. As a central variable, customer trust was found to be an important mediator in the conceptual model.

The findings provide social marketers with important insights on the critical role that customer trust plays in achieving a long-term behavioural shift towards energy-efficient consumption.

Focusing on customer trust in energy-efficiency labels, this study provides empirical evidence of the mediating role of trust in influencing the intention to purchase and the decision to remain loyal to eco-friendly products. Moreover, this paper provides greater clarity on various levers to be activated to enhance the trust that customers have in energy-efficiency labels.

The aim of this paper is to analyse the state of play on energy efficiency with regards to policy, legislation and technological issues in the European Union (EU) and the Gulf Cooperation Council (GCC) countries. Moreover, specific collaboration proposals between the two regions, with respect to the aforementioned, are elaborated on.

The approach of this paper utilizes and integrates the input from a large number of experts through excerpts from extensive international literature, dedicated meetings, bilateral interviews with experts and questionnaires regarding specific proposals for further collaboration.

Collaboration on energy efficiency between the two regions focuses mainly on three directions: policy, technologies and research. Specific collaboration proposals identified relate among others to the establishment of energy agencies and synergies at the policy level, building retrofitting technologies, labels and standards especially for air conditioning and exchange of know‐how on demand side management and third party financing.

Information on the state of play of energy efficiency in the GCC is, for the most part, scattered and fragmented. This paper is the first integrated analysis on the GCC status. Moreover, this paper provides solid collaboration modules between the EU and GCC, through an active participation of experts from both sides.
