A single project sequesters from 100 to 1,000 tonnes of carbon per day in the ground. One tonne of carbon yields 3.67 tonnes of CO2. One tree sequesters 48 pounds of CO2 per year.
100 tonnes dry wood = 50 tonnes carbon
(50 tonnes carbon) * (3.67 tonnes CO2) = 183.5 tonnes of CO2
(183.5 tonnes of CO2) * (2200 lb per tonne) * (240 days per year) / 48 lbs
= 2,018,500 trees per year
Which is about 8,410 trees per day.
