As India flies, it will be environmentally responsible

Around the globe, civil aviation has been a sector that has propelled economic growth, promoted social development and created access. On the other hand, it has also had a limited detrimental impact on our environment, especially on the local environment, as aircraft and airport operations contribute to air, water, soil and noise pollution.


In October 2016, the International Civil Aviation Organization (ICAO) decided to launch an initiative to limit emissions from international aviation. Global consciousness around this has driven numerous policy-driven solutions to be implemented in the sector regarding the efficient operation of aircraft and airports.

As we marked the World Environment Day on June 5 — as a part of the United Nations Decade of Ecosystem Restoration — it is fitting to look at the Indian civil aviation sector and the efforts taken to step into the next era of aviation, with environmental and ecosystem preservation as a core tenet.

Pre-COVID, India was the third-largest domestic aviation market globally, with approximately 140 million passengers travelling annually. The country is poised to become the third-largest overall market in three years.

With just 7.3 per cent of the population using aviation as a mode of transportation, the growth potential in the sector is immense.

While COVID-19 has undoubtedly disrupted the sector, we are making a resilient and robust comeback as we revitalise our economy. Push for initiatives such as the Airport Council International – Airport Carbon Accreditation Programme, which independently assesses and recognises the efforts of airports to manage and reduce their carbon emissions through six levels of certification, is a timely intervention to combat climate change.

India has been following the programme since 2014. Recognising that the Indian aviation sector will undergo exponential growth in the coming years, addressing the environment and sustainability concerns is a top priority for us.

Delhi Airport is the first airport in the Asia Pacific region to have achieved ‘Level 3+, Neutrality’ accreditation in 2016 and the highest accreditation, ‘Level 4+, Transition’ in 2020. Other airports such as Mumbai, Hyderabad & Bangalore International Airports have achieved ‘Level 3+’ accreditation.

Airports Authority of India (AAI) has been taking the lead in implementing technical fixes for route optimisation such as shortening and straightening major air routes, Reduced Horizontal Separation and Performance-based Navigation (PBN). In consultation with Indian Air Force, AAI has optimised airspace utilisation under Flexible Use of Airspace (FUA) initiative. Estimated annual CO2 emissions reduction by establishing the 32 conditional routes come to about 200,000 metric tonnes.

Initiatives to promote the adoption of renewable energy at Indian airports have also been initiated. Since 2014, the installed solar capacity has increased by 44 MWp at 44 airports, helping us achieve a carbon emission reduction of approximately 57,600 tonnes of CO2 per annum at AAI Airports. Today, Delhi Airport meets 100 per cent of energy demand through renewable energy sources. Similarly, with an installed solar power capacity of 40 MWp, Cochin International Airport has become the first fully solar-powered airport in India.

In tandem, initiatives to promote energy conservation and monitoring have also been brought into the fold through regular energy audits. Since 2014, review audits to assess the effectiveness of implementation measures of previous audits have already been completed for 50 airports.

Also, under the National LED program (UJALA, Unnat Jyoti by Affordable LEDs for all), AAI has aimed to replace conventional light fixtures with LED fittings at 85 airports. The work has been completed at 81 airports, and at four airports, work is in progress.

Infrastructure building, which is another essential aspect of India’s expanding civil aviation industry, has been brought under a green and sustainability focus. Delhi, Mumbai, and Bengaluru International Airports have already received a ‘Gold’ rating by the International Green Building Organisation, LEED. Jammu, Chandigarh, and Tirupati airports have received ‘4-star’ ratings from Green Rating for Integrated Habitat Assessment (GRIHA), which is India’s very own green building rating system.

AAI has taken the initiative on waste and water management by minimising the wastage of potable water by processing wastewater and reusing treated water. The Sewage Treatment Plants and Rainwater harvesting are provided/planned with all existing/new projects.

Through the UDAN (Ude Desh ka Aam Nagrik) scheme, 100 new airports are being built to increase access to civil aviation in India.

This development will benefit from the decisions made in hindsight, as green infrastructure, energy efficiency, waste management, and efficient transportation have become vital aspects of India’s expanding civil aviation sector.

Over the next decade, finding the appropriate balance between ecology, economy, and society will be crucial. Civil aviation progress that is synchronous with preserving and restoring our environment and ecosystems is the key to unlocking a safe, healthy and prosperous future for our citizens and remains a cornerstone philosophy of the Narendra Modi government.
