Shell has developed a series of analogies to help customers better understand how carbon is captured and stored using nature. The analogies are used for illustrative purposes only. Whilst Shell takes reasonable care to ensure the data is true and accurate, the figures have been presented in a non-technical way to represent the scale of carbon sequestration. The average tree is defined as one with a 20-cm diameter at breast height, younger trees contain less carbon and others like Redwoods would contain far more carbon at full maturity sequestration of a tree, using three trillion trees (Crowther T. W., 2015) on the planet, which contain 400 giga tons of carbon (Erb, 2017). The average tree contains 0.48 t CO₂
