Commons

Super helpful app to help me understand the environmental impact of my daily behavior, build my carbon intuition, and offset my emissions while I work (with Commons' helpful tips and tricks) to reduce my personal carbon footprint. Would highly recommend it to others.

Big fan of the product. It's been super helpful as I seek to better understand the environmental impact of my daily behaviors and ultimately reduce my personal carbon footprint. Highly recommend others check it out as well.

I've loved watching Commons get launched. They were an early member of Climate Draft and got a chance to play with the tech at one of our events. Super impressive and important for the climate transition.

Hi Product Hunt, and thank you @chrismessina for hunting us! I'm Sanchali, founder of Commons. We help you tap into the power of your spending to build a more sustainable world. All of us have a carbon footprint. I started Commons after manually tracking and lowering mine over 6 years. I learned that our spending choices matter: I lowered my emissions by 30%, and saved about $2,000 a year, just by living more sustainably. However, I also learned just how difficult and complex the journey can be. Together, our household spending influences 65% of global emissions. When we shift our collective spending, we influence companies. I started Commons to make it easy for people to see our carbon influence and lower our emissions. With Commons, you can: → 💡 Measure Your Footprint Automatically calculate the emissions of everything you buy. → 🍃 Offset Your Emissions Balance out emissions you can't avoid by supporting verified climate projects. → 🏆 Build Your Sustainable Life Get practical strategies to reduce emissions that fit your lifestyle. 🔐 Privacy We take privacy and security seriously. You own your information – we never sell your data. We use bank-level security to connect with your transaction history, and encrypt all data. You can delete your account anytime. 💪 Collective action No one can tackle the climate crisis alone. Today we’re releasing a suite of new community features that make it easier to connect with and take climate action with others.

 The app is available on iOS and Android. 🌍 Take action for Earth Week Want to go climate neutral for Earth Week? Use the code PH30 to get $30 off your first month of carbon offsets.
 We're so excited to see what you share and would love your feedback along the way! Please follow our team on the app, and send us your thoughts and ideas on how to improve.


The app offers both a quantified way of tracking carbon emissions through your spending -- and allows you to purchase offsets -- and a qualitative way to work on behavior change in everyday areas of life. Little by little, this app can help regular folks make a huge impact and difference.

Psyched to start learning what to do next with Commons! I dig the tone and the flexibility on what drives me to act.

As someone who has often felt that there is little I can do to benefit the environment, this app is a way for me to actually feel like I can take control of my own impact and contribute to helping make the world a better place in whatever small way I can. Wonderful interface and a truly great product for those that don't know where to start. Great job, team!

I already highly recommended this app for how it puts carbon tracking and climate action at my fingertips - but I’m absolutely loving the new rebrand! Go Commons!
