Carbon Footprint Tracker
What's a carbon footprint?
Whenever we go places, eat things, or use and buy new stuff, we’re contributing to the growing amount of greenhouse gases in the atmosphere. A carbon footprint measures the amount of carbon dioxide equivalents produced as we go about our daily lives. To help you understand and track the carbon footprint of your transactions, we've integrated a Carbon Footprint Tracker into the Westpac App.
Why use our Carbon Footprint Tracker?
Based on the transactions you make using eligible Westpac accounts, including transaction and credit card accounts, the Westpac Carbon Footprint Tracker will help you understand and keep track of your estimated carbon footprint.
Compare your footprint against individual and Australian household averages, to better help you understand where you could make changes to live more sustainably.
Did you know?
The average Australian household is 2.5 people*.
Here's how it works
With the help of our partner Cogo, estimates of your carbon footprint are calculated based on the whole transaction amount, not the individual items in it. So, if you go for lunch at a café, the whole bill, not individual menu items, is used in the calculation.
Search Carbon Footprint Tracker or simply scroll until you see What’s your carbon footprint? Follow the prompts to view.
Transactions are automatically categorised, but you can edit them for more relevant results if you like.
Each category has been assigned an average carbon emissions factor by Cogo. These averages are used to calculate the estimated carbon footprint of your transactions.
Easy-to-read charts let you see how your estimated carbon footprint changes over time, as well as how you compare to Australian averages.

Frequently asked questions
The Westpac App uses two pieces of data to calculate your estimated monthly carbon footprint: the transaction amount, and the transaction’s industry category which has an associated emissions factor calculated based on Australian industry average data. Each eligible transaction is multiplied by an 'emissions factor' (how much greenhouse gas that type of activity emits per dollar spent) to work out the estimated carbon footprint for that transaction.
Our partner, Cogo, has provided these emission factors, mapped to their comprehensive database of industry categories (e.g., home energy, petrol, groceries, fashion, etc) for Australia. For example, $50 spent at an Australian grocery retailer creates, on average, 17.8kg CO2e, the equivalent of driving an average car for 100km.
Your estimated carbon footprint is based on the total transaction amount, and not the individual items making up that purchase.
