This research study measures the impact of academic engagement and operational engagement, the strategies that are used by business schools for sustainability integration. The effectiveness of these strategies is studied through their impact on business students’ sustainability perception, their Corporate Social Responsibility (CSR) attitude, and their current behavior regarding sustainability. It is a quantitative study in which Independent sample t-test is used based on sample of 158 business students from Jonkoping International Business School and Gothenburg School of Business, Economics, and Law. Our findings suggest that the impact of sustainability integration strategies used by business schools is significantly different, that is to say that business school that is using operational engagement in addition to academic engagement is more effective than the business school that is using academic engagement only for sustainability integration. More specifically we found that business students’ sustainability perception, their Corporate Social Responsibility (CSR) attitude and their current behavior regarding sustainability is better in school using operational engagement as compared to the business school that is not using operational engagement. This implies that for sustainability integration it is important to provide practical demonstration and opportunities to business students in order to make them responsible future business leaders.
