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. (shrink)
