Auckland Airport is the largest and busiest airport in New Zealand, located in the city of Auckland. It is the main gateway for international visitors to the country and is a vital hub for domestic travel. Auckland Airport is operated by Auckland International Airport Limited (AIAL), a publicly listed company that is majority-owned by Auckland Council.

As a major player in the aviation industry, Auckland Airport is acutely aware of the need to reduce its carbon footprint and contribute to the decarbonisation of the sector. In recent years, the company has made significant strides towards this goal, implementing a range of initiatives aimed at reducing its energy consumption and increasing its use of renewable energy sources.

One of the key ways in which Auckland Airport has achieved this is through its corporate energy programme. This programme involves a comprehensive review of the airport's energy usage, including electricity, gas and water, with the aim of identifying areas where energy efficiency can be improved. This includes measures such as upgrading lighting systems, installing energy-efficient HVAC systems and implementing smart building controls.

In addition to these energy efficiency measures, Auckland Airport has also invested heavily in renewable energy sources. The company has installed a number of solar panels on the roofs of its buildings, generating up to 160,000 kWh of electricity per year. It has also installed a 100 kW wind turbine, which generates enough energy to power around 30 homes.

Another key initiative undertaken by Auckland Airport is its corporate power purchase agreement (PPA) programme. Under this programme, the company has signed long-term contracts with renewable energy providers, guaranteeing a certain amount of renewable energy to be supplied to the airport over a set period of time. This not only helps to reduce the airport's carbon footprint but also provides a stable source of energy at a fixed price, reducing the airport's exposure to fluctuations in energy prices.

Auckland Airport has also been actively involved in promoting the use of electric vehicles (EVs) and has installed a number of EV charging stations in its car parks. The company has also partnered with a range of stakeholders, including car rental companies and taxi operators, to encourage the use of EVs and other low-emission vehicles.

In addition to these initiatives, Auckland Airport has also been working to reduce its waste and water usage. The company has implemented a range of recycling and waste reduction programmes, including the installation of recycling bins throughout the airport and the use of compostable packaging in its food outlets. It has also implemented a number of water-saving measures, such as the installation of low-flow taps and toilets.

Overall, Auckland Airport is a leader in the aviation industry when it comes to decarbonisation and sustainable practices. Its comprehensive energy and sustainability programmes, combined with its investment in renewable energy sources and promotion of low-emission vehicles, demonstrate the company's commitment to reducing its carbon footprint and contributing to a more sustainable future.
