Event managers are attempting to reduce their environmental impact but have difficulty in managing stakeholders’ behaviors. Yet, event managers have no guidelines to properly engage stakeholders to improve attitudes towards sustainability or evaluate the effectiveness of current communication strategies to convey the parent organization’s prioritization of sustainability initiatives. This research extends and evaluates the fit for the entire Sport Sustainability Campaign Evaluation Model (SSCEM) longitudinally using a sport event’s (the Games’) comprehensive environmental sustainability initiative across multiple campaigns (waste diversion, transportation, energy conservation, and water conservation). Data was gathered (both pre- and post-Games) from caregivers (N = 182) of intellectually disabled athletes who attended the Games. The structural model fit adequately well (RMSEA = 0.072; χ²/df = 1.64). Our results demonstrate the necessary elements to successfully design such messaging campaigns to engage and promote sustainable behaviors at events and how such campaigns can influence sustainability and advocacy behaviors beyond the event in local communities.

活动管理者试图减少对环境的影响，但是在管理利益相关者的行为方面存在困难。但是，活动管理者没有指导方针来适当地使利益相关者参与进来，以改善他们对可持续性的态度，或者评估当前沟通策略的有效性，以传达上级组织对可持续性计划的优先级。这项研究使用运动赛事（运动会）的全面环境可持续发展倡议跨多个运动（废物转移，运输，节能和节水），纵向扩展和评估了整个运动可持续性运动评估模型（SSCEM）的适用性。从看护者（赛前和赛后）收集数据（N = 182）参加了奥运会的智障运动员。结构模型拟合充分阱（RMSEA = 0.072;χ ² / DF = 1.64）。我们的结果证明了成功设计此类宣传活动以参与和促进活动中的可持续行为的必要要素，以及这些活动如何影响活动在当地社区以外的可持续性和倡导行为。
