Mumbai Airport Earns Highest Level 5 Carbon Accreditation
Chhatrapati Shivaji Maharaj International Airport (CSMIA) in Mumbai has achieved a major sustainability milestone, becoming the first airport in India to receive Level 5 Airport Carbon Accreditation, the highest recognition under the global airport carbon management program. The certification highlights the airport’s long-term commitment to reducing emissions, improving energy efficiency, and aligning operations with international climate goals.
The Airport Carbon Accreditation program, administered by Airports Council International (ACI), evaluates airports on their ability to measure, manage, reduce, and ultimately align carbon emissions with global net-zero targets. Level 5 represents the most advanced stage, requiring airports not only to cut their own emissions but also to demonstrate leadership in engaging stakeholders and supporting broader decarbonization across the aviation ecosystem.
CSMIA’s achievement reflects years of investment in sustainability initiatives across airport operations and infrastructure. One of the core measures has been the widespread deployment of energy-efficient LED lighting throughout terminals, runways, and airside facilities, significantly reducing electricity consumption. The airport has also increased its reliance on renewable energy sources, including solar power installations that contribute to lowering its overall carbon footprint.
Waste management has been another critical focus area. The airport has implemented comprehensive waste segregation and recycling programs, along with initiatives to minimize landfill use. Organic waste is processed through composting and bio-treatment systems, while single-use plastics have been progressively reduced across retail, food and beverage, and operational areas.
Water conservation efforts have played an equally important role in CSMIA’s sustainability strategy. The airport operates advanced water recycling and treatment facilities, allowing it to reuse large volumes of water for landscaping, cooling, and other non-potable applications. Rainwater harvesting systems further support responsible water management in a city where resource efficiency is increasingly vital.
Beyond its own operations, CSMIA has worked closely with airlines, ground handlers, concessionaires, and other partners to encourage emissions reductions across the wider airport community. This collaborative approach is a key requirement for Level 5 accreditation and reflects a shift toward shared responsibility in aviation sustainability.
As one of India’s busiest international gateways, Mumbai airport’s achievement sets a new benchmark for airports across the country and the wider Asia-Pacific region. It also aligns with India’s broader climate ambitions and the aviation industry’s global push toward net-zero emissions by mid-century.
With passenger traffic continuing to grow, CSMIA’s Level 5 Airport Carbon Accreditation underscores how major hubs can expand capacity while embedding sustainability at the core of airport operations and long-term development.
