Bangalore International Airport Limited (BIAL) is a public-private partnership company that operates the Kempegowda International Airport in Bangalore, India. The company was formed in 2004 as a joint venture between the Government of India, the Government of Karnataka, and a consortium of private sector companies. BIAL is responsible for the development, operation, and management of the airport, which is the third-busiest airport in India in terms of passenger traffic.

BIAL is committed to sustainable development and has taken several steps to reduce its carbon footprint and promote renewable energy. The company has set a target to achieve net-zero carbon emissions by 2040 and has developed a roadmap to achieve this goal. The roadmap includes decarbonisation of airport operations, adoption of renewable energy, and implementation of energy efficiency measures.

One of the key initiatives undertaken by BIAL to reduce its carbon footprint is the installation of a 3.35 MW solar power plant at the airport. The solar power plant generates around 14,000 units of electricity per day and meets around 40% of the airport's energy requirements. BIAL has also signed a corporate power purchase agreement (PPA) with a renewable energy company to purchase 10 MW of solar power. This will further increase the share of renewable energy in the airport's energy mix.

BIAL has also implemented several energy efficiency measures to reduce its energy consumption. The airport has installed energy-efficient lighting systems, HVAC systems, and building automation systems to optimize energy use. BIAL has also implemented a waste-to-energy project, which converts waste generated at the airport into energy. The project generates around 1 MW of electricity and reduces the amount of waste sent to landfills.

BIAL has also taken several steps to promote sustainable transportation. The airport has implemented a bike-sharing program, which allows passengers and employees to rent bicycles for short trips within the airport premises. BIAL has also installed electric vehicle charging stations at the airport to promote the use of electric vehicles.

In addition to its sustainable development initiatives, BIAL has also implemented several measures to improve the passenger experience at the airport. The airport has implemented a contactless check-in process, which allows passengers to check-in using their mobile phones. BIAL has also installed self-check-in kiosks, automated baggage drop-off machines, and biometric boarding gates to reduce waiting times and improve the overall passenger experience.

BIAL has also implemented several measures to ensure the safety and security of passengers and employees. The airport has installed advanced security screening equipment, CCTV cameras, and access control systems to prevent unauthorized access and ensure the safety of passengers and employees. BIAL has also implemented a comprehensive emergency response plan, which includes regular drills and training programs for employees.

BIAL has received several awards and recognitions for its sustainable development initiatives and operational excellence. The airport has been awarded the LEED Gold certification for its energy-efficient and sustainable design. BIAL has also been recognized as the Best Regional Airport in India and the Best Airport Staff in India by Skytrax, a leading aviation research organization.

In conclusion, Bangalore International Airport Limited is a leading airport operator in India that is committed to sustainable development and decarbonisation. The company has implemented several initiatives to reduce its carbon footprint, promote renewable energy, and improve the passenger experience. BIAL's efforts have been recognized by several awards and recognitions, and the company is well-positioned to achieve its goal of net-zero carbon emissions by 2040.
