New Delhi - India\u2019s first-ever elevated Cross Taxiway at Delhi Airport is scheduled to be ready by December 2022. Delhi International Airport Ltd (DIAL) has completed about 60 per cent of the work on ECT. Once commissioned, the 2.1 km-long dual elevated Eastern Cross Taxiways (ECT) will not only help decongest the airport and improve circulation paths of aircraft, but also reduce approximately 55,000 tonnes of CO2 emission annually.\n\n\n\nThe 2.1 km-long dual elevated Eastern Cross Taxiways (ECT) will also help in enhancing passengers\u2019 experience, as they will have to remain inside a plane for a much shorter duration after landing or during take-off.\n\n\n\n\u201cEnvironment has emerged as a major focus area in the aviation sector. We, at Delhi Airport, have taken various initiatives to improve air quality and reduce emissions. We have been constantly working towards reducing our impact on environment. We have implemented Airport-Collaborative Decision Making (A-CDM) for airport operations at DIAL and all runways operation to minimize the aircraft delay and associated emissions. We have ensured that all airside vehicles run on Compressed Natural Gas to reduce the carbon emission load,\u201d said I Prabhakar Rao, Deputy Managing Director, GMR Group.\n\n\n\n\n\n\n\nAt present, after landing at DIAL RWY 29-11 or to take-off from this runway, an aircraft has to cover a distance of about 9 KM. During this period, passengers have to remain inside the plane. After commissioning of the ECT, the aircraft taxiing distance will significantly go down to just 2 KM as it will taxi along the taxiway parallel to DIAL RWY 11-29 and use the ECT to take a straight path to Terminal 1 or vice-versa.\n\n\n\nThe DIAL ECT will also help airlines to save approximately 350 kg of fuel every time an aircraft uses the taxiing route provided by the ECT from RWY 29\/11 to Terminal 1 and vice-versa. This would translate in reduction of nearly 1,114 kg of CO2 emissions for each aircraft taxiing along this route. Annually, the ECT is estimated to reduce emission of approximately 55,000 tonnes of CO2 from aircraft.\n\n\n\n\u201cConstruction of dual Eastern Cross Taxiways by DIAL, the first of its kind in India, will not only reduce significant amount of carbon emissions but also enhance passenger experience. This is another step towards our goal of becoming a Net Zero Carbon Airport by 2030. The ECT, an integral part of Delhi Airport\u2019s Phase 3A expansion project, would make Delhi Airport future-ready. After completion of this project, the airport would be able to handle 140 million passengers per annum (MPPA),\u201d added Rao.\n\n\n\nIn March 2021, DIAL started mounting of girders of ECT across the pillars in the median of Central Spine Road. A total of 590 girders would be mounted. By the second week of July, over 200 girders have already been mounted.\n\n\n\n\n\n\n\nDIAL has ensured that an environment-friendly approach is followed in the construction of ECT. It is using fly ash, a waste product of coal-fired power plants, in the filling material. DIAL is using around 9,715 MT of fly ash in the construction of ECT. If not used, fly ash would have been disposed in specially designed landfills which could lead to leaching of heavy metals into ground water.\n\n\n\nThe use of fly ash is recognized as an environment-friendly measure as it promotes waste reutilization and ensures that other raw materials used in construction can be reduced, thus making our construction process environment friendly.\n\n\n\nUnder Phase 3A, DIAL is also constructing 4.4-kilometre-long 4th Runway, parallel to runway 11\/29 on the Southern side. Once commissioned the 4th runway would handle the increased traffic movement. Delhi Airport would become the first airport in India to have four operational runways. The 4th Runway also would help reduce Carbon emission significantly.\n\n\n\nAs part of the expansion project, DIAL is also carrying out integration of the departure and arrival terminals of T1, construction of new T1 Apron, 2.1 km-long dual elevated Eastern Cross Taxiways (ECT), landside developments for circulation and connectivity improvements and T3 modification works.\n\n\n\nDIAL is working on the mission of \u201cbuilding a sustainable future\u201d. It includes its highly ambitious plan of becoming \u201cNet Zero Carbon Airport\u201d by 2030. To fulfil its ambition of becoming a net zero carbon emission airport, DIAL has initiated a number of key infrastructure development projects. One of these initiatives is the development of the Eastern Cross Taxiway (ECT).\n\n\n\nDIAL has achieved of \u201cLevel 4+, Transition\u201d accreditation under Airport Carbon Accreditation program of ACI. Delhi Airport is the first airport in Asia Pacific and only the second airport globally.
