• The total amount of CO2 fixed over the lifetime of the tree. In these estimates we have assumed a life of 80 years, since after this age, a typical tree in Canada requesters little additional CO2.
• The number of trees is based on the amount of CO2 removed annually by trees that have been planted. This removal would occur for 80 years.
• Average consumption of 8 litres/100km.
• Average consumption of 6 litres/100km.
• Average consumption of 4 litres/100km.
