The largest airport in New Zealand is planning to invest more than $3 million in projects that help reduce its energy use in the next three years.

Auckland Airport has set a target of saving six GWh of energy – enough to power around 750 homes annually – and cut carbon emissions by 1,000 tonnes every year.

The first stage includes the installation of an energy monitoring system to identify its energy use and potential savings in businesses across the airport’s business district.

The initiative is supported by the Energy Efficiency and Conservation Authority (EECA).

Mike Underhill, Chief Executive of EECA said: “[Auckland Airport] already improved energy use significantly throughout its terminals but this programme breaks new ground in taking a proactive partnership approach with tenants.

“The company has ambitious goals to reduce energy use and carbon emissions and has identified that it must work in partnership to achieve these.”
