Amrita University is committed to ensure that water is used most judiciously and reused to the maximum extent possible. Amrita Institute of Medical Sciences campus under Amrita University is being constructed to be GRIHA (link is external)and LEED(link is external)-certified: a green building, with no carbon footprint, zero wastewater discharge, and to be powered eventually by more than 45% solar power. Construction materials used in the project are also environmentally friendly. More than 70% of the campus acreage is planned as a green area filled with local varieties of trees, plants and shrubs and water bodies.

We also adopt the following practices across our campuses:
