For an effective consumer energy policy, it is important to know why some households require more energy than others. The aim of the study described here was to examine whether there is a relationship between the total household energy requirement, on one hand, and value patterns, the motivation to save energy or the problem perception of climate change, on the other. To examine these relationships, we held a consumer survey among 2304 respondent households.We did not find significant differences in the energy requirement of groups of households with different value patterns, taking into account the differences in the socio-economic situation of households. Only for the 'motivation to save energy' we did find that the least motivated group requires 10 GJ more energy than the average and most motivated groups; this is about 4% of the total household energy requirement.This means that a self-regulating energy policy, solely based on the fact that a strategy of internalising environmental responsibility will not be effective in saving energy. There are indications that a social dilemma is one of the reasons why people's consumption patterns do not conform to their value patterns, problem perception or motivation to save energy. r

ABSTRACT. According to the Dutch Ministry of Economic Affairs (2001), transparency by means of Sustainability Reporting should lead to better Corporate Social Responsibility (CSR) performance of companies. Sustainability Reporting should also give consumers the information they need to purchase the most sustainable products available (Dutch Ministry of Economic Affairs, 2004). This article analyses the driving factors influencing CSR and Sustainability Reporting at seven breweries in the Netherlands. It also gives a better understanding of organizational behaviour with reference to CSR and the reasons breweries have for Sustainability Reporting. The Dutch government has no intention of forcing organizations to publish a sustainability report, since it is trying to diminish the volume of legislation. Rather, the government prefers to rely on the willingness and initiatives of organizations to make CSR a success. In 2006, the Dutch Ministry of Economic Affairs will evaluate the effect of its CSR policy. But is it a success already? During our research, breweries appeared to find CSR more important than Sustainability Reporting. Sustainability reporting is, for most breweries, not the way to reach stakeholders. Most stakeholders have their own means for receiving information e.g. annual reports, meetings, public statements and press releases. Although small breweries think CSR is very important, they feel no pressure from outside to publish a sustainability report. For them it is very complex and expensive to publish a sustainability report. Large breweries feel pressure from many stakeholders to be transparent, but not on a regular basis. We conclude from this research that CSR does not stimulate Sustainability Reporting, but neither does Sustainability Reporting stimulate CSR.
