DIAL's Environment Policy

DIAL's Climate Resilience Program

Aircraft Noise abatement is one of the key areas the DIAL focuses on. In order to manage aircraft noise, DIAL along with stakeholders such as Director General of Civil Aviation (DGCA), Air Traffic Controller (ATC), Airport Authority of India (AAI) and Central Pollution Control Board (CPCB) have implemented various noise mitigation measures. Further, ICAO balanced approach is followed to reduce the noise impact.

As per MoEF&CC notification, the aircraft noise levels for busy airport is 70 dB(A) Leq for day time (6 AM to 10 PM) and 65 dB(A) Leq for night time (10 PM to 6 AM). Besides, the Lmax level for aircrafts are 105 dB(A) for day time (6 AM to 10 PM) and 95 dB(A) for night time (10 PM to 6 AM).

The followings are the various noise mitigation steps taken by Delhi Airport:

Distribution of aircraft movement which has been done in the form of mixed-mode operation of the runways that provides benefit from noise experienced by a particular region
Continuous Decent Approach (CDA)
Noise complaint system
Restricted operation of chapter-2 aircraft (old aircrafts) and
Automatic aircraft noise monitoring System in all the approach of runways to monitor noise levels around airport and enable to identify noisy aircrafts.
Aircraft tracking system has been installed along with Aircraft Noise Monitoring terminal at IGI Airport.

All the above measures are implemented to managing the noise aspect successfully at IGI Airport. To lodge a complaint regarding Aircraft noise in your area please call us at 011-47198600

Air quality management & Emission reduction are focused areas at Delhi Airport; DIAL being an environmentally responsible organization has taken numerous initiatives to improve the overall air quality aspects in Delhi Airport. Some of the key initiatives adopted by Delhi Airport are.

Integration of Green Building concept in building design and operation, energy efficient infrastructure, efficient lighting, use of day light, adoption of Smart Building Management System (BMS), adoption of ISO standards etc. to reduce overall energy consumption and reduce its impact on Air pollution.
Installation of solar power plant (7.84 MW) and use of renewable energy
Use of Bridge Mounted Equipment’s (BMEs) such as Fixed Ground Power Unit (FGPU) and Pre-conditioned air service, eliminates the use of Auxiliary Power Units (APU) by aircrafts, which are run by ATF. Thus the use of BMEs reduces air pollution significantly.
Delhi Airport has installed dedicated CNG fuelling station at airport and most of the airside vehicles use Compressed Natural Gas (CNG), reducing emission load.
Delhi Airport has adopted multi modal connectivity to improve passenger access to airport by metro as well as road transport. In addition to metro connectivity to Terminal 3, Terminal 1 has also got metro connectivity.
Improved Road Infrastructures: Six lane road connections to T3 building from NH8, 1.5 km long six lane northern access roads to reduce the vehicular congestion and resulted emission.
Delhi Airport developed a large portion of the airport area as landscape area with mostly native and adaptive plants, leading to significant improvement in air quality.
To avoid fuel spillage and also reduce movement of oil tankers/fueling vehicles, Delhi Airport has developed dedicated fuel hydrant network system.
Use of Airport-Collaborative Decision Making (A-CDM) for airport operation and all runways operation to minimize the aircraft delay and associated emission.
Use of green taxing procedure such as TaxiBot to reduce ATF burning during taxing procedures.
Use of battery operated vehicle in terminal, apron (for luggage trolley) and cargo.
Apart from this DIAL also carries out regular air quality monitoring in and around the airport area.

Water is one of the key elements required for the efficient, hygienic and customer friendly airport operation, thus water management is one of the major focus areas at Delhi Airport. DIAL’s key objectives are-Sustainable development and management of water resources by continual assessment, conservation, augmentation, protection from pollution and safe distribution.

In order to reduce the dependency on fresh water, DIAL follows the 3R model i.e. Reduce, Reuse and Recharge water. Our key water sustainability initiatives are-

DIAL has set up 5 MLD advanced water treatment plant to provide good quality water to passengers in Terminals.
DIAL has installed 16.6 MLD plant to treat and reuse the wastewater for various purposes. This state of the art Sewage Treatment Plant (STP) has been designed and operating to achieve zero discharge and reduce water consumption. Treated wastewater is being used for HVAC makeup, toilet flushing and landscaping purposes which help in reducing and optimizing fresh water demand.
DIAL has installed rain water harvesting wells in the storm water drains to improve water recharge.
Use of low flow fixtures and appliances for reduced water consumption such as low flush water closets and cisterns.

Cleanliness & waste management is extremely important at DIAL for ensuring hygiene, achieving high service quality standard and safety measure against bird strikes. Delhi Airport works exclusively with waste management companies which employ the highest environmental standards to handle different kind of waste streams. DIAL’s objective is to ensure effective waste management system for collection, segregation, storage and safe disposal of waste and comply with all regulatory requirements.

Waste such as Municipal Solid Waste, Hazardous Waste, E-Waste, Construction and Demolition waste are handled and disposed as per the legal framework. DIAL regularly checks to ensure that these standards are maintained. Training and Awareness to all the stakeholders on Waste Management and Environment Management System are regularly provided. Waste papers are being sent to recycling unit for the waste paper reuse.

DIAL’s key waste management initiatives are-

Installation of two bin system across the entire Delhi Airport infrastructure for ensuring source segregation of waste. DIAL has also implemented four bin systems in key locations to further promote segregation of waste into different streams such as – paper, plastic, glass/cans and food waste.
DIAL has also made a commitment to make Delhi Airport “single use plastic free” airport. This initiative will ensure reduced single use plastic waste generation
DIAL has implemented paper recycling program for waste paper generated from office and administrative area
There are employee engagement initiatives are in place to promote and waste to wealth programs

Extensive flora and fauna studies have been undertaken to determine the biodiversity values that exist within the airport boundary. The findings have been further supplemented through additional studies that are being undertaken as part of the Environmental Impact Assessment (EIA). Animals are rehabilitated with the help of wildlife and forest department and NGOs to various Wildlife Sanctuaries of Delhi.

DIAL has carried out proper landscaping and extensive tree plantation along with the construction activities at airport. Trees have been planted around the water bodies of Delhi. A very intensive and dense landscaping works have been carried out at the IGI Airport, using thousands of medium to big shrubs and trees as per master plan. Entire landscaping is irrigated with water conserving irrigation system with treated waste water. Automatic irrigation system with dedicated pipe line network is laid down around the airport to facilitate the treated waste water usage.
