Case study

Melbourne Airport

Level 1

Asia Pacific

Why did your airport decide to become accredited at Level 1?

Melbourne Airport wanted to develop an in-depth understanding of our carbon footprint to inform targeted management actions and identify future emissions reduction targets. The level 1 Mapping process means we have a robust, independently verified base year carbon footprint on which to demonstrate emissions reductions over time.

Further, the mapping exercise means we now have a clear understanding of where our emissions hotspots are. We know that electricity and natural gas consumption accounted for over 99% of our 2016/17 carbon footprint. Using this information means we can target energy savings projects at areas that will make the biggest difference.

What benefits does accreditation bring to your airport?

Airport Carbon Accreditation has allowed Melbourne Airport to demonstrate our commitment to better understanding and then reducing the carbon emissions under our control. Accreditation has helped us to focus our efforts on developing a carbon management plan and emissions reduction targets to prepare for achieving level 2 Reduction. Teams across the airport have started working collaboratively to achieve these goals. This will increase the efficiency in which energy reduction projects, and hence greenhouse gas emissions savings are delivered.

What would you recommend to other airports that are developing their carbon footprint?

After going through the process ourselves, our recommendations include:

  • Make sure your team has a strong carbon accounting background.
  • Engage with the independent verifier early on in the carbon footprint exercise so as to gain a clear understanding of the auditing requirements, and what information they will need from your team.
  • Identify key emissions hotspots in your carbon footprint for focusing emissions reductions efforts.
  • Be ambitious! Don’t just stop at the carbon footprint, start thinking about emission reduction opportunities and targets from the start of the accreditation process.
What are your future carbon management plans?

Melbourne Airport is developing a Carbon Management Plan to identify opportunities across the estate to reduce our carbon emissions. A few key projects currently in train include:

  1. Energy efficiency program: This program aims to reduce 20% of the airport’s base building energy usage by the end of 2020.
  2. Solar adoption program: We will have >10MW of ground mounted solar PV systems installed by 2021.
  3. Tri-gen: Utilising our tri-gen power plant more (using natural gas and a more efficient power plant rather than brown coal grid electricity).
