  • Food (how much meat do you consume ?)

Carbon offset

We currently offer 3 different carbon projects. All very different, but all certified to the highest standard.

Choose between: 

1) Plant a tree (Panama)

2) Forest protection (Brazil)

3) Cookstoves (Rwanda)

The philosophy is simple. Calculate your carbon footprint - and offset yourself. 

Download the app - use the carbon calculator - and be surprised too see, that for most people - it will cost you less than a Netflix subscription per month.

Once you carbon offset, you will receive a badge, that you can share on social media, by mail etc - to share with your friends, that you have chosen to become a carbon neutral human being.

Create a group

Imagine, that you have chosen to offset your carbon emission. Thereby one person more in the world today, that is carbon neutral.

That's great - but you can do even better. You can get your friends and family to follow your lead.


That way - you can multiply yourself.

We have made it easy for you do to exactly that. Right from within the app, you can invite friends via social media, email etc. Just follow these easy steps:

1) Create and name a group.

2) Invite friends.

3) Follow each other in the group.

You can then have a friendly "battle" over who is doing best - having the lowest carbon footprint.
