About this game

Play and collect CO2 cards for various environmental projects. Use them to offset real-life CO2 emissions and get rewarded with top cryptocurrencies.

Open booster packs, play minigames and complete tasks, while helping real life green projects operate.

Introducing Base Carbon Tonne - BCT!
BCT is a carbon index token, backed by various offsets from multiple projects, bridged by the Toucan Protocol. When a player offsets CO2, the game gives BCT rewards at a 1 BCT = 1 Tonne ratio, as well as FONE and a Certificate Card. Each Certificate Card represents a 1kg CO2 offset.

Collect 100 Certificate Cards and mint a personal Offset Certificate in your name! Each certificate has a unique number and also includes your name and the amount of CO2 offset. All your certificates are saved to your profile and you can share them with anyone, or print them.

Each player receives a unique digital CO2 Player Card which keeps track of their personal carbon offset.

I like the concept and ideas behind this app, coz its not a game, really. after the recent update tho there seems to be more bugs. 1. no more reward videos, but task for watching vids is still there. I watched vid to open booster but task did not acknowledge. 2. Tap bottle game before update no probs. Now every second tap does not register? So end up with half oxygen. 3. Prices for magnesite and other packs are unfair.I have 500000 Fone.$10 after 18mths of play.No return for investment.

the app is working fine, but it as good as useless. Cause for donkey years you would be mining only oxygen and at the of the day it would only be transformed to cards and the cards will only give you few fone, which makes all your efforts in vain, and even the redemption of diamonds and completion of levels that used to give 1000fone is no longer there.., for over 6months I couldn't get up to a thousand fone Except they go back and correct, I don't recommend this app to anyone it a waist of time

Dear Subzi, I think you didn't check in details the new version of Green Karma. You still have the redemption of the collectibles and they give you now even bigger reward then before. You can also earn much more FONE than before by selling your cards on the market for FONE. You can make more than 10,000 FONE per month. So please check this

Dislike the update. Green Heo perks are no longer worth the price I paid for them. I am earn much less oxygen than before update. Can now only obtain FONE and BCT; BTC, LTC, ETH and TRX where removed. The premium pass feature is an attempt to get more in-app purchases. The extra perks aren't worth the amount of money spent. Can no longer offset projects with FONE and the rewards are reduced for projects offset with the cards. Also ad's won't load for me anymore. Extremely dissatisfied.
