Research Goal
• To develop a framework to address the adverse impact of Conventional Brick Manufacturing and its use for Sustainable Environment.
• To develop a platform for promoting interaction among researchers, academicians from across the country.
• To enhance understanding of the current activities and research capabilities in the country and thereby identifying key lacunae
• Exploring ways to more effectively link climate research and action program
