Let us plant a tree or a whole forest for you. Help the environment. Become CO2 neutral today. For free. Core Mechanics Firstly you receive a digital seed. You need to water it. You water it by completing lessons. By completing 2 lessons you water your digital seed to a tree. And the PineOx team plants a real tree. The first lesson is the CO2 calculator. It calculates your annual CO2 footprint based on your habits and lifestyle. It allows the PineOx app to calculate for how long planting one tree will make you CO2 neutral. After planting your first tree the countdown starts. It shows you for how long you will remain carbon neutral. To remain CO2 neutral you need to continue completing lessons and plant trees. Inviting Friends, Gifting Trees & Tree Impact Map The first seed is free and is given to every user who joins PineOx. To open access to the following seed you need to watch some ads or invite a friend. You can invite any amount of friends. Every friend who joined via your invite code gives you an additional seed. Every user of PineOx has Tree Impact. Tree impact represents planted trees. It includes trees planted by you plus trees planted by friends you invited and subsequently by friends invited by your friends. Right after installation, you can make 2 gifts for your friends. You can make gifts only to users who haven’t yet been present on the platform. After claiming their gift they join your network and their planted trees influence your tree impact. Transparency & Actual Tree Planting Because many green initiatives aren’t transparent we made Tree Impact Map. Tree impact map allows you to see tree impact of every member of the community. Information about who invited who is seen by everyone. We at PineOx plant trees by ourselves. We do not pass it to some third-party organization. You can check the image and location of every tree planted by the PineOx Team. All the images and locations for planted trees are available in the Tree Impact Map section of the app
