A friend of mine has created a startup that you can buy credit to plant trees (take a look at moretrees.eco for more info).
They have an API at https://plant.moretrees.eco/Moretrees-API-v1-Documentation.docx but I don’t have the knowledge to create an integration myself. Anyone fancy a side project?
I am thinking it would be a nice idea to be able to a see how many trees I have planted so far, automate the planting of a tree when I have left the house (and gone for a drive) and so on
