We review the literature (2007–2016) on the quality of sustainability decisions and we introduce an integrative conceptual framework that distinguishes between a beneficial and a detrimental path that explain the influence of stakeholder diversity on the comprehensiveness of sustainability decisions. We argue that decision quality increases when stakeholder interest diversity is expressed through task conflict (extensive information sharing and exploration). Decision quality is compromised if stakeholder diversity is suppressed and false consensus occurs, that is, when task conflict is not tolerated or when decision makers fail to acknowledge and work with their differences. We conclude by discussing three generic recommendations that focus on inclusive stakeholder selection, norms for engagement and process consultation as ways of developing constructive collaboration in multiparty systems.

我们回顾了有关可持续性决策质量的文献（2007-2016年），并引入了一个综合性的概念框架，该框架区分了解释利益相关者多样性对可持续性决策的综合性的影响的有利与不利之道。我们认为，当通过任务冲突（广泛的信息共享和探索）表达利益相关者的利益多样性时，决策质量会提高。如果利益相关者的多样性受到压制，并且出现了错误的共识，即当不容忍任务冲突或决策者无法承认和解决分歧时，决策质量就会受到损害。最后，我们讨论了三项针对包容性利益相关者选择的通用建议，
