Dive into the detail of our pillars and grades. Plus, if you’d like to see your own carbon removal project on our site, see how it measures up.
Our 6 scoring pillars
We’ve developed 6 scoring pillars in collaboration with leading scientists at Edinburgh University. It’s the total score of all 6 pillars that equals a Carbon Char Grade.
The certainty of the mass of carbon removed from the atmosphere in kg.
The quality of reporting on the carbon removal project.
The stability of the carbon once removed from the atmosphere.
The length of time that the carbon will remain locked away based on existing scientific evidence.
The likelihood that the organisation in charge of the removal will look after it.
Additionality + Novelty
The certainty that your purchase made the removal happen and that it wouldn’t have happened without it; combined with how innovative the technology is.
