The complexity and the challenges in present era have compelled us to think towards the need for a teaching approach that prepares students for better sustainable consciousness and citizenship with right decision-making ability. Change is the law of nature while awareness and analysis are major milestones for transformation. Hence this research is taken up to sensitize and measure the consciousness of students with both conventional pedagogy and sigma 6Q pedagogy on environment sustainability. For the primary data, a total sample of 180 students of 7, 8 and 9 grade of our school were chosen randomly to study the effectiveness of sigma 6Q pedagogy on students which revealed that if the students are informed of sustainable development at initial stages of middle schooling, they are able to process, analyse and experiment with no rigid outlook and freely come out with solutions which can help them to develop and further inculcate habit to solve real-world sustainability problems. Henceforth our education system having factual knowledge with text-based curriculum and conventional teaching methodologies, needs transformation with evolved pedagogy having a solution-based approach for environmental issues for meeting the needs of present age students
