Sydney Airport is one of the busiest airports in Australia, located in the suburb of Mascot, just 8km south of the central business district of Sydney. The airport is owned and operated by Sydney Airport Corporation Limited (SACL), which is a publicly listed company on the Australian Securities Exchange (ASX). The company is a leader in the airport operators sector and has been recognized for its efforts in decarbonisation, corporate energy, corporate power purchase agreements (PPAs), and renewable energy.

Sydney Airport has been committed to reducing its carbon footprint and has set a target to achieve net-zero carbon emissions by 2030. The company has been working towards this goal by implementing various initiatives such as energy-efficient lighting, solar power, and waste reduction programs. In 2020, the airport was awarded a Level 3+ accreditation by the Airports Council International (ACI) Airport Carbon Accreditation program, which recognizes the airport's efforts in reducing its carbon footprint.

One of the key initiatives that Sydney Airport has undertaken to achieve its decarbonisation goals is the installation of a 1.2 MW solar power system on the rooftop of its international terminal. The solar panels generate approximately 1.4 million kilowatt-hours of electricity annually, which is equivalent to the energy consumption of around 270 homes. The solar power system has helped the airport reduce its carbon emissions by approximately 1,200 tonnes per year.

Sydney Airport has also been actively engaged in corporate energy management, which involves the optimization of energy use across its operations. The company has implemented various energy-efficient technologies such as LED lighting, smart building management systems, and energy-efficient HVAC systems. These initiatives have helped the airport reduce its energy consumption and costs while also reducing its carbon footprint.

In addition to reducing its own carbon footprint, Sydney Airport has also been promoting the use of renewable energy through corporate power purchase agreements (PPAs). In 2019, the airport signed a PPA with energy retailer Flow Power to purchase renewable energy from the Bomen Solar Farm in regional New South Wales. The PPA will enable the airport to source approximately 75% of its electricity from renewable sources, which will help the company achieve its decarbonisation goals.

Sydney Airport has also been actively engaged in promoting the use of electric vehicles (EVs) and has installed EV charging stations in its car parks. The airport has partnered with Chargefox, a leading EV charging network provider, to install six ultra-fast charging stations that can charge EVs in just 15-30 minutes. The charging stations are powered by renewable energy, which further supports the airport's commitment to decarbonisation.

Overall, Sydney Airport has been a leader in the airport operators sector in Australia and has been recognized for its efforts in decarbonisation, corporate energy, corporate PPAs, and renewable energy. The company's commitment to reducing its carbon footprint and promoting the use of renewable energy is commendable and serves as a model for other companies in the industry. As the world continues to transition towards a low-carbon economy, Sydney Airport is well-positioned to play a leading role in this transition.
