اقرأ أكثرFor concrete and steel, the use and end-of-life stages see only small changes in embodied carbon. For timber, however, subsequent changes are signifi cant. In timber scenario 1, sequestration causes a small, temporary period of negative carbon emissions. This lasts only while the building is in use, ending abruptly upon demolition.

اقرأ أكثرOn average, OD wood contains about 50 percent carbon by weight. Therefore a 2,062-ft 2 home could store 10,500 pounds of carbon or sequester 38,500 pounds of CO 2 eq, 2 assuming wood MC is 12 percent. This value does not include nonstructural wood products, which may have a shorter service life.
