Paper Finding: The greatest CO 2 and FF savings from wood use are by avoiding the excess FF energy used to make steel and concrete structures (avoidance pathway).

Paper Context: Consequently, efficient wood use could make an important but not overwhelming contribution to saving CO 2 and FF globally, even if only part of its potential savings were realized. The greatest CO 2 and FF savings from wood use are by avoiding the excess FF energy used to make steel and concrete structures (avoidance pathway). Wood products are more efficient than wood energy for CO 2 and FF savings; however, up to 37 % of the world's annual CO 2 emissions and 27% of the FF use could be saved if all wood growth not used in construction were used for energy (energy pathway; Figure 6b-c) .
