Manual dishwashing process – a pre‐assigned behaviour?

Global studies have observed many techniques of manual dishwashing causing different levels of performance and using quite different amounts of water, energy, time and detergent. It is not known, however, if these techniques are pre‐assigned to a person and persist when dishes are washed under different conditions, or are adapted to the specific type of dish‐cleaning process. Here we explored this question in a study with 40 test subjects selected equally from Germany and East European countries by asking them to wash two place settings of dishes with different amounts of soil three times. The results showed that the test subjects did not adapt their washing‐up behaviour to the amount of soil. In general, no significant differences were found in the water, energy and detergent consumption for all test subjects. Only the time used by the German test subjects to wash the fully soiled dishes was significantly longer compared with the dishes with only a quarter the quantity of soil, and no significant difference was observed for all other parts. The only significant difference found between the level of soiling of the dishes was the cleaning result achieved: The less soiled the dishes were, the better the final cleaning result was, and this related to all test subjects. This lends support to the proposition that the consumers did not adapt their washing‐up behaviour to the specific circumstances of the dishwashing job to be done but retained some pre‐assigned behaviour.     

Application of Best Practice Tips in manual dishwashing in Germany and Spain

Investigations on the consumer behaviour of manual dishwashing have shown that there is a large variety of ways of how to wash up by hand, and the corresponding resource consumption is affected accordingly. In order to reduce resource consumption in manual dishwashing while achieving an acceptably good cleaning result, Best Practice Tips have been established (published in Fuss et al.) on the basis of laboratory experiments and the knowledge of everyday behaviour. This study is aimed at verifying the potential to save resources in real life when consumers are applying Best Practice Tips for manual dishwashing. A 4‐week in‐house study was run in two European countries, and data of the manual dishwashing behaviour were acquired before and after training on the Best Practice Tips. The results of both periods were compared with each other and between the countries. The test participants in Germany needed approximately 30% less water and 40% less energy, on average, in the period in which they applied the Best Practice Tips; in Spain, nearly 50% less water and 60% less energy for dishwashing in the period after the training. It has to be taken into consideration, however, that individual savings are very different due to specific living conditions, household sizes, practices in dishwashing and more or less prejudice against the Best Practice Tips.     

An examination of the values that motivate socially conscious and frugal consumer behaviours

This article extends social psychological research on the motivations for sustainable consumption from the predominant domain of ecologically conscious consumer behaviour to socially conscious and frugal consumer behaviours. A UK‐based survey study examines relationships between socially conscious and frugal consumer behaviours and Schwartz's value types, personal and socio‐political materialism, and demographics among the general public. Socially conscious consumer behaviour, like its ecological counterpart, appears to be an expression of pro‐social values. In contrast, frugal consumer behaviour relates primarily to low personal materialism and income constraints. As such, it does not yet represent a fully developed moral challenge to consumerism.     

Do consumers act in a sustainable way using their refrigerator? The influence of consumer real life behaviour on the energy consumption of cooling appliances

Over recent decades, energy savings and resource conservation have become increasingly important issues for debate, and this includes the residential sector. Since the introduction of the European Energy Label, the energy consumption of appliances has decreased drastically. Additionally, a number of guidelines have been published to assist the consumer in adopting more energy‐saving behaviours. Refrigerators and freezers in particular are covered by these recommendations because they are large energy consumers in domestic households. In order to understand the influence of consumers' real life circumstances and their behaviour in relation to the energy consumption of refrigerators, a web‐based survey was carried out. A total of 1011 participants in four European countries completed a questionnaire to allow the researchers to gain information about refrigerator characteristics and consumer behaviour in relation to refrigerator use. As well as demographic and socio‐economic characteristics of the participants, data were collected on refrigerator configuration and specification, ambient conditions (ambient temperature, position near any heat sources), and consumer behaviours such as shopping frequency, loading of the refrigerator, door opening and food consumption. The study has shown that recommendations on energy efficient usage are not always observed. A major finding of the present study is that for 25% of refrigerators, correct operation is not ensured as these appliances are operated outside the temperature ranges specified according to their climatic classes. This suggests a lack of consumer information on this topic. Consequently, guidelines and recommendations will have to be revised and their dissemination to be improved in order to ensure the sustainable and safe use of domestic refrigerators.     

Automatic dishwashers: efficient machines or less efficient consumer habits?

Increasing costs for energy and water influence consumer decision making when purchasing white goods, such as dishwashers. Since the implementation of the European Energy Label, considerable improvements in water and energy consumption of dishwashers has been achieved, and for consumers, efficiency has become one of the main buzzwords when buying any major new household appliance. However, ownership of an efficient dishwasher in itself does not guarantee savings in energy and water during the course of the dishwashing process. Conservation of resources also requires changes in consumer behaviour. This paper provides empirical data on consumers' dishwashing habits in everyday life in four European countries, deals with the influence of their behaviour on the efficiency of the dishwashing process and highlights savings potentials in the usage of dishwashers. It reports on the results of a survey involving a total of 1209 online interviews conducted in winter 2006/2007. The survey data have been analysed to reveal the importance of various product attributes for consumers and show that low water and energy consumption values are the most important consideration for the respondents in terms of their purchasing decision. But this is compromised, at least in part, by less efficient dishwasher use, e.g. in pre‐rinsing dishes before placing them into the dishwasher and in the programme choice. In addition, differences in manual dishwashing practices between households with and without a dishwasher, as well as between countries, will be shown. Finally, conclusions are drawn for greater sustainability in the dishwashing process.     

Reconceptualizing risk perception: perceiving Majority World citizens at risk from ‘Northern’ consumption

The premise of this paper is that the consumption behaviour of ‘Northern’ citizens places Majority World citizens at great risk. A theoretical evolution suggested in this paper is the extension of the notion of risky consumption to include the impact of consumption on the human security of others. Until people can envision that their consumption behaviour places others at risk of exposure to harm, they will not see the need to perceive, assess and manage the risk. The paper tenders a preliminary reconceptualization of risk perception, using the conventional consumer behaviour model constructs of personal, distribution channel and situational factors. From this new perspective, instead of judging whether the good or service is risky for a ‘Northern’ citizen to consume, risk perception scholars would examine people's perceptions of whether their consumption places fellow citizens at risk, the people labouring and producing the goods and services.     

Convergence in global markets and consumer behaviour

Consumer behavioural scientists such as economists and marketing researchers are interested in the degree to which global convergence is occurring with respect to various consumer behaviour dimensions, particularly the extent that consumption patterns in products appear to evolve and become more similar across different parts of the world. With increasing internationalization and cultural cross‐fertilization, the traditional societies of the world are converging in many ways. The strategic marketing of flavoured alcoholic beverages is a particularly interesting example of this evolutionary process to convergence. Consumers in countries of different cultural originations are developing preferences for the same products and show increasing sign of converging around global product identity. This article presents the results of a study analysing the evolutionary process.     

Comparing sustainable consumption patterns across product sectors

In this paper, we present findings from two qualitative studies where we explored sustainable consumption practices through examining consumers' information search and decision-making processes for recent purchases of five categories of goods/services: fast moving consumer goods (such as foodstuffs and household products), white goods (such as fridges and washing machines), small electrical products (such as TVs and computers), green energy tariffs (such as electricity from renewable sources) and tourism (such as flights). This research has provided us with a set of rich data which explores the nature and extent of sustainable consumption practices across different product sectors. A comparative analysis has allowed us to draw out patterns of consumer behaviour for different product and service types. Our findings suggest that even the same green consumer will not use the same information sources or decision-making criteria, consider the same options or focus on the same industry actors, for products in different sectors. However, we have identified some degree of consistency in purchases within sectors. We present these sector-specific patterns of consumer behaviour and highlight differences in the criteria utilized and the research norms in each sector.     

Factors affecting households’ seafood purchasing decisions in Auckland,New Zealand: an empirical analysis

This paper uses the binary choice model to identify the factors that are significantly influencing the household purchase decisions of seafood products for home consumption in Auckland, New Zealand. It is found that ‘quality’ and ‘cooking easiness’ are the main product attributes that significantly influence households’ choices of seafood in Auckland. Also, the representative household has shown a strong preference for fresh and other alternative seafood products, including processed, smoked and canned, over frozen products. Retail outlets are found to be more attractive to the household purchasing seafood for home consumption. The New Zealand seafood industry may find this baseline study useful as a guide to developing future research structure on the domestic market.
