Message from the CEO

Dear Stakeholders,

It is a genuine pleasure for me to share my thoughts with you for the first time in our ESG report. Ever since my start at IndiGo in September 2022, I have been equally excited and proud to be a part of this wonderful Company. I am happy to present our third ESG report for IndiGo, in which we aim to show our commitment of being a responsible airline.

The financial year 2023 was a year of first recovery and thereafter growth. In the first half of the year, we witnessed a global recovery from Covid-19. With easing of travel restrictions, air traffic rebounded remarkably, and passenger traffic for IndiGo surpassed pre-Covid levels. In the second half of the year, a lot of exciting initiatives were launched as part of our new strategy. As a result of the improved environment and the initiatives that were undertaken, IndiGo’s financial performance considerably improved. We are extremely proud of all our teams whose efforts and determination helped us to deliver our courteous and hassle-free service to a record-high of approximately 86 million passengers.

In FY 2023, we formulated, communicated and started to execute our new strategy of ‘Towards new heights & across new frontiers’. This will be, for the years to come, the next chapter of the inspiring IndiGo story. We have identified three pillars for our (growth) strategy - Reassure, Develop and Create - which we will focus on in parallel. The wide range of initiatives that were collectively set in motion across our Company under these three pillars have already started to yield results in all areas. Our ESG agenda is mostly part of the second pillar - Develop. You can find more information on our achievements across our three pillars in our Annual Report.

Company which cares for the planet and the people. Our

Approach To Sustainability

At IndiGo, we strive to deliver our customer promise in the most sustainable way possible. Sustainability has always been a priority for us and it is ingrained and embedded into the mindset with which we conduct business.

Being an airline, our main lever is our fleet. Around 80% of our fleet is from the Airbus A320 NEO family, which comes with two advantages. Firstly, it is 15% more fuel efficient and secondly, it is 50% quieter1 than the older generation aircraft. This has helped us reduce our CO2 emissions by 20% per ASK (available seat kilometres) compared to the 2016 baseline, placing us amongst the global leaders in low emissions per unit and noise abatement category. Next to this, sustainability is integrated at the operational level, and we are making a series of investments towards more responsible flying including single engine taxiing, optimal climb and descent profile, introduction of electric ground vehicles, combo units, electronic flight bags and water conservation techniques on-board.

Giving wings to the nation

At the end of FY 2023, we operated more than 1,800 daily flights, covering 104 destinations, with our fleet of more than 300 planes. With our vast network we are enabling air travel to all large, medium, and smaller cities across India. Right from 2006, when IndiGo started, it has been our mission to connect the vast and diverse India, supporting social cohesion, mobility and economic progress. And so, in the past financial year we had formulated our purpose as ‘Giving wings to the nation, by connecting people and aspirations’. This is something we have lived by since our inception and will continue to fuel going forward. ESG is naturally connected to our purpose as we want to support the country in its development, while being a responsible

IndiGo is committed and focused on deploying sustainable aviation fuel (SAF) as an alternative fuel option. We acknowledge that SAF is an important next step to make further progress in the low emissions journey. However, the limited availability of SAF globally restricts our reach on this front. We have meanwhile partnered with a research organisation in India and are well engaged with oil marketing companies, who are leading these initiatives in India. We continue to show our commitment going forward.

With our CSR arm, IndiGoReach, we enhance green cover in ecologically fragile regions of the country, while also engaging the community to take ownership of the forests. We have planted and are maintaining more than 140,000 saplings across 380 acres of land. Other environmental initiatives include reduction of carbon emissions through commissioning of biogas units. This has helped us offset about 121,000 Carbon Emission Reductions.

Our social approach

At IndiGo, we have always nurtured a strong 6E culture. Made in IndiGo is one of the programmes that makes me very proud to be part of this Company as we give room for the talent of our employees. In the second half of the financial year, we have seen an uptick in our employee promotor scores and we are continuing to build on initiatives that strengthen our employee engagement and talent management.

Roughly half of our employee strength is women and we are proud to have the highest number of women pilots in the world. We are committed to IATA’s initiative of 25 by 2025 and are focused on increasing the share of women in leadership positions. Our teams pushed our diversity agenda further in FY 2023 with sensitisation trainings to help create an inclusive environment for all, including the LGBTQ community and people with disabilities.

We served 800,000+ customers on our regional routes under the UDAN scheme, which focuses on connecting the remote parts of the country with both metro and non-metro destinations. In line with our purpose, this initiative serves three objectives. Firstly, it helps many to fulfil their dream to fly, secondly it helps in generation of trade and commerce opportunities, and thirdly, it helps in creation of new and structural employment opportunities in remote parts of the country. Also in a broader context, with our high seat share in tier-3 cities of approximately 70%, we are proud to have a substantial contribution to the economic development of the nation.

We reach out to people not only with our planes, but also with our hearts. The initiatives of our CSR arm, IndiGoReach, continue to make a positive impact on the environment, restoring heritage, and impacting the lives of underprivileged women and children. I had the opportunity to visit one of our projects near Guwahati, and found it greatly rewarding to see the results - both in terms of the income growth and future perspectives for women. Here, our purpose of ‘Giving wings to the nation’ also comes to life.

Our approach to governance

Our Board of Directors plays a critical role in establishing a robust governance framework. They provide strategic guidance and oversight to ensure that our operations align with the Company’s objectives and values. Our strong Board enables us to establish and maintain an effective governance framework that promotes ethical conduct, sound decision-making, and sustainable growth. We continue to build a robust ethics culture at IndiGo. During the year we undertook multiple initiatives, including our Ethics Ambassador Programme and the Annual Ethics Week Celebration. Our Ethics Survey had a 99.5% response rate.

Way forward

Sustainability, social initiatives, and strong governance are a part of our ESG efforts. I hope this report gives you a better understanding of our commitment to being a responsible airline that cares for the planet and its people. ESG reporting in the Indian context is relatively new. We are taking the required efforts in this direction by adhering to requirements set by SEBI under BRSR, and aligning with international reporting frameworks like GRI and SASB. I am confident that with the consistent and earnest efforts of our 32,000+ motivated team members, we will continue to make progress in our ESG efforts, while continuing to deliver a courteous and hassle-free service to our customers.

Let me conclude by expressing my deepest gratitude to all our customers, stakeholders and partners for their unwavering faith in us. For our 6E stars, and all the colleagues at the various disciplines and geographical locations, I would like to take a deep bow for your support, dedication and relentless efforts for our customers, our ESG commitment and the Company itself.

In FY 2024, we will reach new heights as we gear up to become a 100 million passenger airline. By the end of this decade, we are looking to double in size and scale. Committed to remain at the forefront, our growth story will be well-aligned with our ESG commitment. As a result, we will be able to further give wings to the nation. India by IndiGo!
