Solar panels generate 125 kW of power, saving approximately 1.5 Lakhs (668 Omani Rial) worth of energy bills every month. Sixty-five cows produce between 120 l and 200 l of milk daily, which is used for the canteen and distributed to community patients. The cow dung is fed into the biogas plant (the dome), where it\u2019s converted into 2.5 commercial cylinders of gas. Leaves from the trees are collected and converted into compost, which is used to fertilize 2.5 acres (108900 sq. feet) of land. Wastewater is treated in a sewage treatment plant, and the purified water is then used to irrigate the 2.5 acres (108900 sq. feet) of land and water the campus gardens.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSION:<\/jats:title>\n                    <jats:p>Eye hospitals should prioritize routine carbon audits using GHG Protocol scopes, Miyawaki-type of gardening in limited areas, and solar integration to achieve net-zero emissions without compromising outcomes.
