The Indian Army is making significant strides in reducing its carbon footprint and transitioning towards energy security and self-reliance. Recognizing the need for sustainability, the Army is implementing various green initiatives across its operations. One key development is the establishment of the world's highest hydrogen-based microgrid in Ladakh, which will replace diesel generators and prevent an estimated 1,500 tonnes of CO2 emissions annually. Additionally, the commissioning of a 1-megawatt solar plant and the pilot testing of hydrogen fuel cell buses highlight the Army's commitment to renewable energy and zero-emission transport. The deployment of solar thermal heating systems and the creation of eco-friendly military shelters further demonstrate the Army's dedication to innovative and sustainable practices. Collaborations with organizations like NTPC REL, IOCL, and partnerships with innovators like Sonam Wangchuk showcase the Army's holistic approach towards reducing its environmental impact. By engaging in carbon audits and setting net-zero goals, the Indian Army is not only striving towards carbon neutrality but also setting a positive example for sustainability in the military sector.
