A recent mintBlue feature added to the SDK and your mintBlue console is the ability to purchase trees through our partner Sumthing. Via API, you could setup tree purchases to compliment and offset the Co2 of any other transactions you’re creating. Via Coda you can set up your own Co2 calculations and request for tree purchases to then be completed in a click of a button!
If you’re interested in this feature, makes sure to get in touch with us here in Coda or at support@mintblue.com. Thanks!
