Using the Make an Impact Calculator is Simple ...

The Make an Impact calculator is designed to give you a comprehensive assessment of your household water and energy use.

Here are some simple step-by-step instructions to get you on your way towards being part of the solution to climate change.

[Note: the Make an Impact calculator is only available to Alcoa employees and their families at this stage.]


Step 1: Get your family sitting around the computer – Make and Impact is a great family activity which teaches kids about the importance of water and energy conservation, and living green. They’re probably learning about climate change at school - this gives them a way to really get involved (best suited to 10-15 year olds).


Step 2: Gather the following info:

  • Your electricity and gas/LPG bills for the past year
  • If you use wood heating, an estimate of how much wood you have used in the past year
  • Information on dollars spent/litres of fuel used by your household vehicles for the past year
  • Details of any flights that members of your household took during the past year
  • Information on the types of heating, cooling and hot water systems used in your home
  • The energy or star ratings of your household’s appliances, including washing machines, fridges, dishwashers, clothes dryers
  • Knowledge about how, and how often you use energy and your appliances throughout the year
  • Knowledge of the types of light globes used in your home
    Also, walk around your home and observe the way your household uses energy, taking note of the types of appliances, house furnishings and building techniques used in your home.

Step 3: Click on the link to the right and login-in (or register for the first time***) and answer a series of simple questions. Your calculation should take you around 25 minutes to complete.  It’s a ‘one click system’ for quick and easy data entry.

If you’ve forgotten your login details, insert your username (which is your email address) and then hit the ‘forgot password’ button - a new password will be sent to your email automatically.


Step 4: When you’ve completed your calculation, you’ll have the opportunity to offset your emissions, with a link straight through to Greening Australia’s Breathe Easy program – of which Alcoa is a founding sponsor (this is entirely voluntary and requires a financial donation).


Step 5: Following your calculation you will be provided with a personalised action report tailored specifically for you and your home.  Use the action report to make energy and water improvements in your life. The action report will give you:

  • Prioritised actions based on cost effectiveness and maximum emissions reduction; and 
  • Some no-cost actions so you can make improvements straight away without digging into your pocket.

Step 6: Come back to this website all year round, to get more tips on the best ways to lower your carbon footprint.


Step 7: Re-calculate your household's greenhouse and energy use using the Make an Impact calculator every 12 months to track your progress over time.

Step 8: Give yourself a pat on the back for being part of the solution to climate change!  We can all make an impact, so spread the word to fellow Alcoans who are not signed up yet.

Step 9: Tell us about the changes you’ve made around your home and whether your family are involved. Email us your story and some photos of you and your family to


What if I don’t have time to complete the whole calculation in one go?
Don’t worry, simply save your calculation (top right of calculator) and you can go back to the same spot in your calculation later.


More about the Make an Impact calculator …

The calculation is broken down into two parts:

1. Energy Consumption
2. Householder Survey.

The Energy Consumption section assesses your household’s greenhouse footprint based on actual information that you provide, for example; information from electricity and gas bills.

The Householder Survey seeks to understand your energy use habits so that when combined with the information you provide in the Energy Consumption section, the final report can advise you on where you can make savings, and customise an action plan to suit your individual needs.

Important note***

Please note, when registering for Make an Impact for the first time, your registration will need to be approved by the Make an Impact team. This typically takes one business day. Once approved, you will get an email letting you know. Then, you can login to the calculator and begin your first calculation!
