Climate Action
DIAL’s climate action strategy focuses on reducing carbon footprint and enhancing environmental sustainability through a multi-faceted approach. Delhi Airport is the World’s largest airport to achieve ACI Level 5 Airport Carbon Accreditation with net zero carbon emissions in Scope 1 and 2.
GHG Management
For GHG management, DIAL follows the target-oriented approach of Airports Council International’s Airport Carbon Accreditation (ACA) Program. In 2020, DIAL set a target to achieve net zero carbon emission airport by 2030. In 2024, Delhi Airport is the World’s largest airport to achieve ACI Level 5 Airport Carbon Accreditation with net zero carbon emissions in Scope 1 and 2. Continuous focus on energy and fuel conservation adoption of renewable energy and other less emission intensive processes pursued by Delhi Airport has ably complimented the Carbon Reduction initiatives. https://unglobalcompact.org/what-is-gc/participants/168946-GMR-Airports-Limited
Delhi Airport has implemented a range of climate change adaptation and mitigation measures to reduce its environmental impact and build resilience to climate-related risks.
Green Infrastructure
The airport has incorporated climate resilience into its infrastructure design, ensuring that buildings and facilities can withstand extreme weather conditions. DIAL has achieved LEED Gold as New Construction and IGBC Platinum as Existing Building for Terminal 3. In 2019, Terminal 3 had also received “Platinum Level” in Performance Excellence in Electricity Renewal (PEER) certification system from the United States Green Building Council (USGBC). Developed as a green building in accordance with LEED standards, Delhi Airport's Terminal 1 holds the LEED Platinum certification.
Flood Management
Rainwater harvesting, rainwater retention tank and stormwater drainage systems have been strengthened to manage heavy rainfall and prevent flooding, ensuring uninterrupted operations during monsoon seasons.
Operational Resilience
Contingency planning and risk assessments help the airport adapt to climate-related disruptions, such as extreme temperatures or air quality issues, ensuring smooth operations.
Renewable Electricity
DIAL has installed 7.84 MW solar Power plant in airside area of the airport. DIAL also sources additional renewable based electricity through open access and reduce energy indirect emissions. Operations at Delhi Airport are sustained by renewable power. Currently our operations are powered by 100% renewable electricity. DIAL has reduced its electricity related emission to Zero.
Green Transportation
DIAL has adopted electric vehicles and developed the required infrastructure at Delhi Airport. DIAL’s objective is to make Delhi Airport as Green Transportation Hub and is working with its airline partners operating from Delhi Airport for adopting EVs wherever possible. DIAL has also adopted other technological measures such as green taxing by utilizing TaxiBots at Delhi Airport, which reduces aircraft’s fuel consumption during taxi and corresponding emission reduction from flight (taxi out).
Zero Waste to Landfill
DIAL has been awarded the prestigious IGBC Net Zero Waste to Landfill Platinum certification for its Terminals 1, 2, and 3 – making it the first and only airport in India to receive this recognition for the Operations Phase.
Operational Excellence
Delhi Airport has implemented several operational excellence measures to reduce emissions and enhance sustainability. The Airport Collaborative Decision Making (A-CDM) system optimizes air traffic flow, reducing delays, fuel consumption, and aircraft emissions. Additionally, Bridge Mounted Equipment (BME), including Fixed Electrical Ground Power Units (FEGPU) and Pre-Conditioned Air (PCA), replaces aircraft auxiliary power units (APU) at Terminal 3 and Terminal 1 aerobridges, further reducing emissions. The adoption of electric vehicles and infrastructure development promotes clean transport, while TaxiBot facilitate green taxing, reducing fuel consumption and emissions during taxiing. The new Eastern Cross Taxiway (ECT) reduces taxi times, saving aviation fuel (ATF) and cutting CO2 emissions. Together, these measures contribute significantly to operational efficiency, sustainability, and a reduced carbon footprint at Delhi Airport.
Responsible Suppliers & Service Providers
DIAL is ensuring that all the suppliers and service providers who are all directly associated with Delhi Airport have responsibility towards ESG Goals by providing Supplier ESG code of conduct and to enhance disclosures.
