Purpose: This study aims to asses students' sustainability consciousness (SC) in relation to their perceived teaching styles in seven public sector institutions in Pakistan. Design/methodology/approach: A survey technique was used to collect data from respondents. Grasha's (1996) Teaching Styles Inventory and Gericke et al.'s (2019) Sustainability Consciousness Questionnaire were used to collect data pertinent to teachers' teaching styles and students' SC, respectively. This study's population was 1,986 students studying in seven educational institutions. A sample of 993 students was selected for the study. Out of the 993 questionnaires distributed, only 753 respondents returned the questionnaire completely filled, resulting in a response rate of 75.83%. Descriptive statistics and structural equation modeling (SEM) were used to analyze the data. Findings: The results show that students' mean scores on environmental and social dimensions were higher compared with the economic dimension. Similarly, students' scores were relatively higher on the knowledge and attitude dimension while lower on the behavior dimension. Moreover, the expert and formal authority teaching styles were the most prevalent teaching styles. Furthermore, SEM results show that various teaching styles affected students' knowledge and attitude; however, only the delegator teaching style affects all three dimensions of SC. Research limitations/implications: This research has implications for educational institutions and policymakers to ensure dedicated efforts to promote and integrate education for sustainable development into the educational system and achieve sustainability goals by 2030. Practical implications: The study findings will help future teachers to effectively integrate sustainability education into their classrooms. Originality/value: This research expands the discussion on the effectiveness of various teaching styles on SC in teacher education programs.
