Without context this link is just bad. Plant growth will not reduce CO2 levels because biosphere is temporary store or carbon (since it is a part of the carbon cycle)
We are putting carbon (into the atmosphere) that was previously buried. So putting a tiny bit of it back into plants doesn't help because:
- those plants will die and release the carbon back
- the number of plants added is inconsequential compared to the deforestation
- the number of plants needed to offset additional carbon is humongous
It might be something built using digital payments with no transaction fee (and a percentage for currency conversion)
Not possible globally, but in India and the Nordics, such standards are already in use. (No private apps like venmo which can't inter-operate don't count)
