    TAKE2 Climate Change Pledge

    Welcome to our TAKE2 profile page.

    We’re committed to tackling climate change. That’s why we’ve made the TAKE2 pledge. Check out the work we’ve been doing to reduce our emissions and our plans for the future.

    Make the TAKE2 pledge and join us in helping keep the temperature rise under two degrees.

    Our pledge
    Melbourne Airport’s pledge summarises the actions we’ve committed to through the implementation of our 2013 Environment Strategy and Airport Master Plan. Further opportunities to reduce the airport’s carbon footprint, meet the Victorian Government’s goal of net zero emissions by 2050, and support Australia’s commitment to the international Paris Agreement on climate change have been embedded in our draft 2018 Environment Strategy and Master Plan.

    Our stories
    You can find out more about what we’ve already achieved, and our future plans – by visiting our website or page 34 of our 2016 Annual report.

    Emissions and Offsets

    Melbourne Airport annually offsets all carbon emissions from its vehicle fleet and staff travel.

    Since January 2017 the on-site 8MW tri-generation plant has generated approximately 25 per cent of all airport energy, while reusing waste heat for space heating and cooling.

    Working On
    Melbourne Airport is working to achieve Level 1 and Level 2 Airport Carbon Accreditation – an independently verified carbon baseline for the airport and a carbon reduction strategy for benchmarking our progress against the global aviation industry.

    Wherever feasible, we will develop ‘green infrastructure’ (rather than brown) for stormwater management. Green infrastructure creates habitat, sequesters carbon emissions and demands little to no energy to run and maintain, reducing our carbon footprint.

    Energy Management

    Informed by ongoing monitoring we have refined our understanding of how the airport uses energy.

    Working On
    Continue to identify and implement strategies to reduce both overall and peak energy consumption.
    As the airport continues to grow and develop, investigate how to mitigate the heat island effect, including its impact on cooling demand.
    Continue to reduce utilities consumption per passenger and per square metre.
    Invest in smart systems:

    • Enhance forecast models for more accurate capacity planning so that we can meet our demand efficiently
    • Launch smart monitoring and controls such as SCADA, BMS and GIS.
    Diversify and decentralise the airport’s energy supply. In addition to making the airport generally more resilient, this strategy also minimises transmission losses.

    Renewable Energy

    Working On
    Prioritise clean or renewable energy sources when increasing capacity. Actively investigate the development of a solar array within the airport precinct.

    Explore on-site waste-to-energy opportunities.

    Establish a trigger for transitioning to solar energy.


    Enhanced passive energy efficiency of our buildings through HVAC CO2 control systems and installing insulation to keep cool on hot days.

    A comprehensive upgrade of the majority of lighting across occupied buildings and carparks to LED or T5 compact fluorescent lighting.

    Achieved LEED Silver rating for Terminal 4 development.

    Avoiding over-conditioning by adjusting air conditioning temperatures according to the season.

    Working On
    By 2019 complete an assessment to refine our understanding of building energy consumption and behaviour.

    By 2020 tune the buildings’ heating, ventilation and cooling systems.


    Insulated boilers and high temperature heating hot water pipes to reduce heat loss.

    Installed variable speed drives for the majority of air-handling equipment, pumps, fans and refrigeration.
    Working On
    Pursuing energy efficiency through the way we buy, operate, maintain and replace office equipment.


    Invested in fit-for-purpose vehicles to reduce trip numbers and per-trip carbon emissions.
    Working On
    Assessing our fleet to identify opportunities for reducing carbon emissions.


    Working On
    Embed sustainability into our procurement policy.

    Waste Reduction

    Working On
    Review existing waste management practices, identify opportunities for improvement and develop a whole-of-airport waste management plan, with specific targets to optimise recycling and minimise waste (both overall and per passenger) generated within the airport terminal precinct.

    Business Leadership

    Working On
    Plan for the foreseeable impact of climate change.

    Identify further opportunities to communicate what we are doing to reduce carbon emissions to our customers, travellers and the community.

    Our Stories

    Low-carbon energy
    At the end of 2016 the airport completed its 8MW tri-generation plant to generate low-carbon electricity from gas and reuse waste heat for heating and cooling the terminals. The tri-generation also provides an on-site energy source, which saves transmission losses while diversifying the airport’s power supply.

    Car park lighting
    In 2014 as part of the Victorian Energy Efficiency Target (VEET) we upgraded the airport’s car park lighting, reducing car park energy consumption by 47 per cent or 2 million kWh/year. This is enough energy to power around 374 average Victorian homes, and has reduced our CO2 emissions by 2,829 tonnes – equivalent to keeping more than 700 cars off the road.
    Cool roofs
    The roofs of Terminals 2 and 3 have become ‘cool roofs’ through SkyCool, a heat-reflective paint that has reduced radiant heat gain (and the buildings’ cooling load) by approximately 20 per cent.
    Free-cooling chiller
    As part of the airport’s thermal network expansion, a free-cooling chiller was installed. The system has been able to operate without engaging a compressor for 20 per cent of the year.
