A sustainability goals app to live greener, one step at a time
Bemelio is a free app where you set sustainability goals, from going zero waste to cycling to work, and follow your progress with steps, updates and simple tracking tools. You move forward alongside people heading in the same direction, and you decide whether each goal is public or private.
How can a sustainability goals app help you live greener?
Bemelio is a free social network built around personal goals, and ecology has its own category. You pick a subcategory such as zero waste, carbon footprint, energy and consumption, sustainable food or green mobility. The app suggests example goals to get you started. Then you give your goal a title in your own words and choose whether it is public or private.
From there, every small change becomes visible. Each time you move forward, you post an update with text, a photo or a video: your first compost bin, your new bike commute, a few lines about a week without single-use plastic. Put together, those updates tell the story of your progress from the very start to the finish.
- Zero waste
- Carbon footprint
- Energy and consumption
- Sustainable food
- Green mobility
How do you track your eco-friendly progress?
Big ecological goals can feel vague. Steps make them concrete. You split your goal into steps you can tick off: switch to a reusable bottle, find a bulk shop nearby, set up a compost corner, plan a bike route to work. Each ticked step shows you how far you have come, even when the finish line still feels far away.
Depending on the subcategory, your goal comes with built-in tracking tools. The streak tool lets you tick off every day you made progress, whether that was a meat-free meal or a car-free commute. On green mobility goals, the cycling tool logs the distance, duration and elevation of each ride. On energy goals, the savings tool follows your progress toward a target amount with a chart.
Many tools offer a Post as update option, which turns your real figures into a card on your goal. With savings, only the percentage reached is published, never the amount. That way you can show others how you are doing while keeping the details that matter to you.
Why work on sustainability goals with other people?
Changing your habits alone can feel like a drop in the ocean. On Bemelio, you follow people and see their updates in your feed. You can react and comment, and others can do the same on yours. Seeing someone else ditch plastic or cycle through the rain is a simple, concrete reminder that these changes are within reach.
Circles bring together people heading in the same direction, so you can find others working on zero waste or greener travel. Private messaging lets you swap tips one to one. With a co-goal, you share a goal with another person who becomes its co-author: handy for a household going zero waste together or two colleagues cycling to work.
When you are proud of a step, an update can become a visual you share in a story on social media, with a link to your Bemelio profile. The Discover section of the app also presents experts, such as coaches and specialists, as well as events you might want to look into.
- Follow people and see their updates in your feed
- Join circles of people with the same direction
- Message others privately
- Share a goal as a co-goal
- Turn an update into a story visual
What method helps you stick to green habits?
Start small and specific. 'Go zero waste' is a direction. 'Bring my own bags every time I shop' is something you can do this week. Pick a single change, make it part of your routine, then add the next one. Breaking a large goal into small steps keeps it realistic and stops you from trying to change everything at once.
Regularity tends to matter more than intensity. A short action you repeat often is easier to keep than a big effort you make once. The streak tool helps here, because you see each day you showed up. If you miss a day, simply pick it up again the next. Progress is rarely a straight line, and that is perfectly fine.
Measure what you can. Note the rides you take, the meals you cook from local produce, the steps you tick off. Look back at your updates now and then to see the road behind you. That record helps you notice what works for you and adjust what does not, without guilt and at your own pace.
- Pick one change at a time
- Write it as a concrete action
- Repeat it regularly
- Track it and look back
- Adjust without guilt

Tools to follow your green goals
Depending on the goal you choose, Bemelio gives you simple ways to see your progress.
Streak
Tick off every day you made progress and watch your streak grow. It works across all ecology subcategories, from zero waste to green mobility.
Cycling
On green mobility goals, log each ride with its distance, duration and elevation, and follow your progress over time.
Savings
On energy and consumption goals, track your savings toward a target amount with a chart. In an update, only the percentage reached is shown, never the amount.
Steps
Break your goal into steps you can tick off, so a big ambition turns into a clear list of actions.
Updates
Post text, photos or videos each time you move forward. Together, your updates tell the story of your goal.
Co-goal
Share a goal with another person who becomes its co-author, so you can work on it together.

Frequently asked questions
Is Bemelio free?
Yes. Bemelio is free to download and free to use. It is available on iPhone through the App Store and on Android through Google Play. You can create your sustainability goals, break them into steps, use the tracking tools and post updates without paying anything.
Is my goal visible to everyone?
Only if you want it to be. When you create a goal, you choose whether it is public or private. A public goal and its updates can be seen by others, who can react and comment. A private goal stays yours, which is useful if you prefer to start quietly.
Which ecological goals can I set on Bemelio?
The ecology category covers zero waste, carbon footprint, energy and consumption, sustainable food and green mobility. The app suggests example goals in each subcategory, such as composting your waste or cycling to work, and you are free to write your own title for the goal.
Can I track my bike commutes?
Yes. On green mobility goals, the cycling tool lets you note each ride with its distance, duration and elevation, and follow your progress. You can also use the streak tool to tick off every day you left the car at home.
Can I work on a green goal with my household or a friend?
Yes. A goal can be shared as a co-goal with another person, who becomes its co-author. It suits shared projects like going zero waste at home or cycling to work with a colleague. You can also join circles of people heading in the same direction.
Can I share my progress outside the app?
Yes. An update can become a visual you share in a story on social media, with a link to your Bemelio profile. It is a simple way to show your green changes to the people around you and maybe inspire someone else to start.
