This study addresses that question by analyzing the influence of contingency factors on the adoption of sustainability practices and the use of EMA tools to improve the environmental performance of wineries. The research was carried out through a survey with 171 Brazilian wineries, and structural equation modeling regression was used to test the hypothesis. The results suggest that contingency factors, such as environmental uncertainties, environmental strategy, and technology influence the adoption of sustainability practices and the use of EMA tools and have a positive impact on the environmental performance of Brazilian wineries. The study also shows that there is no direct effect between the use of EMA tools and environmental performance, but there is a positive impact on financial and nonfinancial performance, indicating that in a winery setting EMA tools are mainly used for cost saving and economic purposes rather than environmental impact. This study extends our understanding of how wineries design sustainability practices and deploy EMA tools in response to contextual contingencies. Drawing on contingency theory, we highlight the role of environmental uncertainty, strategy, and technology in shaping sustainability behavior. Our findings further show that the use of EMA tools by Brazilian wineries often leads to economic benefits.\n"]
