Environmental impacts and certification: evidence from the Milan World Expo 2015
研究调查了米兰居民对2015年世博会环境影响的感知和认证了解程度，发现居民认为影响不大，少数人知道认证，且对认证的正面看法与对事件的态度正相关。
Purpose This study aims to examine residents’ perceptions of environmental impacts and certification for the Milan World Expo 2015 as well as their overall attitude toward the mega-event. Design/methodology/approach A survey of Milan residents based on a convenience sample led to 221 useable questionnaires. Findings Residents perceived that the Expo will have minimal negative and positive environmental impacts. A minority of residents were aware of the environmental certification of the event. The less agreeable residents were with the perceived negative environmental impacts of the event, the more agreeable they were that a certification of event sustainability should limit the damage to the natural environment. Residents’ perceptions of the certification were positively related to their overall attitude toward the event. Research limitations/implications The findings cannot be generalized to other mega-events but have several managerial implications in relation to the need for information provision to residents and better communication of the certification by event organizers and planners. Originality/value Despite rising concerns about environmental issues related to hosting mega-events, there is no research on perceptions of a certification of event sustainability by residents.
