Attitudes toward repository projects cannot be explained merely on the basis of perceived risks, trust, or technical information. Issues of justice and fairness frequently arise when burdens and benefits are to be allocated. A fair distribution across the various parts of a given territory of the waste to be stored is unlikely to be accomplished as it is contingent on appropriate geological formations and other factors. The process by which the specific distribution is determined and accomplished needs to be taken (...) into account as well. Thus, justice evaluations of both the distributive outcome and the process itself, by which the outcome is accomplished, are likely to affect people’s attitudes toward and acceptance of siting decisions. Data from a number of methodically different studies conducted over the last eight years on site selection in Switzerland suggest that a fair procedure is more essential than a fair distribution to a consensus about the decisions made. As a consequence, even normative assessments of the fairness of a distribution of nuclear waste must consider procedural justice as a valuable indicator, independently of the particular shape of the distribution. However, contextual factors, such as the wider nuclear energy strategy of a country, may compete with procedural fairness in terms of importance. Even though fairness is a requirement it does not guarantee acceptance. It may, however, enhance acceptability from a moral standpoint. (shrink)
