A full version app for Android, by CO2 Cards.

Green Karma is a free, social, and fun way to offset your carbon footprint by playing a virtual game. It’s a lot of fun and a great way to make a real change.

The game is based on the concept of “offsets”, which is a way to reduce your carbon footprint by paying someone else to do the same thing. You can play the game on your phone or tablet, and it’s completely free.

To play, you need to install the game on your device and create a profile. You will be given a player card that will be used to offset your carbon footprint. When you play, you need to make a decision about how much carbon you want to offset. It can be any amount, and it’s up to you.
