Abstract
Responding to the lack of evidence for visualizing the monetary value of professional sport teams’ socioeconomic and environmental impact, this study aimed to calculate the socio-economic and environmental impact of a Japanese professional soccer team’s social business activity (i.e., lawn production business) using a Social Return on Investment (SROI) framework. We conducted nine interview investigations with each stakeholder related to this activity and the results showed that the socio-economic value of the targeted activity was JPY 33,422,183, while the inputs were JPY 29,449,784, suggesting an SROI ratio of 1.13. Therefore, for every JPY 100 invested in a lawn production business, socio-economic and environmental benefit worth JPY 113 was generated. This study contributes to advancing impact research in sport by shedding light on the monetary value of the socio-economic and environmental impacts of professional sport teams’ activities. Additionally, this framework provides practical implications for team managers looking to utilize activities as a management strategy through cost-effective investment and resource optimization.
