One Small Step: Sustainable Living App

Offers in-app purchases

The One Small Step app makes sustainable living fun, simple and rewarding.

Rather than feeling like you have to do everything and anything under the sun, the One Small Step app curates the most impactful activities that help you to significantly reduce your carbon emissions.

Using a behavioural science approach, One Small Step breaks down the actions you need to take to become more sustainable, with simple, easy-to-follow steps. The app’s tailored programs help you build sustainability skills and foster long-term environmental practices that have an outsize impact on your carbon footprint. Programs cover food, energy, waste, transport, and the stuff you buy.

What this app does

Get a breakdown of your carbon footprint. Start by completing a short quiz about your lifestyle to receive a personalised sustainability roadmap. You’ll see how your carbon footprint compares with the average Australian’s, and gain clarity on how you can reduce your environmental impact.

Take action with highly tailored programs and challenges. You’ll get recommendations on the most impactful actions you can take based on your lifestyle. For example, if you’re currently renting, then the app will show you options like setting up an indoor composting bin that is rent-friendly.

Track your progress. The One Small Step app allows you to track the environmental impact you have, alongside the broader community’s impact, ticking off achievements as you go so you can gain a sense of momentum and self-efficacy.

Make sustainability part of your daily life. The app allows you to schedule new activities into your calendar, and get reminders for taking action.

Build eco-friendly habits. Set weekly goals so you can develop sustainable lifestyle habits like riding your bike instead of driving, using a reusable coffee cup, and eating a vegan meal. As you tick off your habits, you’ll see the impact you’re making in real-time.

Magnify your impact with your friends, family & work colleagues. You’ll be able to set weekly challenges with your friends & create teams so you can encourage each other and stay motivated to live more sustainably.

As featured on ABC News Online

"Making small changes doesn't require a lot of brain power but we tend to overthink things and worry they won't actually contribute to helping the big picture. In actual fact, those smaller actions can really build a sense of motivation and encourage people to be more mindful of what they're consuming and why."

“Our ultimate goal is to reduce the cognitive barriers that prevent people from sticking to green habits, something behavioural science research has only begun to understand in the past few years.”

About One Small Step

Our mission is to use behavioural science to help millions of people reduce their personal carbon footprints down to the United Nation’s 2050 goal of 2 tonnes of CO2e per person, per year.

We've set ourselves the ultimate goal of growing our community to the same number of active users as FitBit. For reference, that's about 28 million users. Even if these users only get part-way through our programs, reducing their annual footprints by 6 tonnes on average, we'd be able to achieve the same carbon impact as closing down 40 coal-fired power stations.

It’s ambitious, but we need your help to achieve this: The more people who use the One Small Step app, the more insights we gain into how to most effectively support you to reduce your carbon. Right now, we need your feedback and input on what is working for you, and what isn’t in this version of the app. You can give us feedback on Facebook, Instagram, Twitter or by emailing us at

We regularly update the collective impact One Small Step users are having on our website.
