Mumbai’s Chhatrapati Shivaji Maharaj International Airport (CSMIA) has strengthened its position as one of India’s greenest transport hubs, with its latest sustainability report revealing that 98.7% of waste generated at the facility was diverted from landfills in FY 2024–25. The airport also recorded a 5.5% reduction in energy intensity, reinforcing its commitment to climate action and operational efficiency.
According to Mumbai International Airport Limited (MIAL), the operator, the report underscores how technological innovation, renewable energy use and community partnerships are helping reshape airport management towards a more sustainable and inclusive model. In the last financial year, CSMIA handled 55.12 million passengers and achieved an 8.1% year-on-year growth in cargo movement. It also became the first airport in India and only the third globally to achieve Level 5 Accreditation for Airport Customer Experience from Airports Council International (ACI). CSMIA has maintained its ACI Level 4+ ‘Transition’ status for climate action while operating entirely on 100% green energy since August 2022, extending this transition to all concessionaires.
Officials said that energy optimisation has been achieved through smart building systems, LED retrofitting, and renewable power procurement, enabling a tangible reduction in emissions. The airport’s IGBC Platinum certification renewal for Terminal 2 further demonstrates its focus on sustainable infrastructure. Environmental management has been paired with biodiversity protection. In FY 2024–25, the airport planted over 2,000 native trees under the Miyawaki plantation model, part of a larger plan to enhance local biodiversity and carbon sequestration. Water sustainability initiatives include extensive rainwater harvesting systems, sewage treatment plants, and audits designed around the ‘reduce–recycle–recharge’ framework.
Beyond infrastructure, MIAL has also prioritised social impact. Through partnerships with the Adani Foundation, programmes on healthcare, women’s empowerment and community welfare reached more than 4,000 people last year. Employee development initiatives under the ‘Saksham’ programme recorded over 60,000 training hours, focusing on inclusion, leadership, and gender equity. On the passenger front, CSMIA is now a frontrunner in smart travel facilitation. With 147 e-gates—the highest across Indian airports—and nearly 30% Digi Yatra adoption, it is reshaping how passengers move through terminals. Accessibility upgrades such as tactile flooring, wheelchair services, sign language training and sanitary pad dispensers also reflect the airport’s human-centric approach to mobility.
Experts say CSMIA’s ongoing efforts demonstrate how large transport infrastructure can lead India’s green transition, aligning with the nation’s net-zero goals while improving user experience and community well-being.
