Why and how key assumptions impact calculations of the substitution benefit of substituting wood for non-renewable materials. Argues that the degree to which substitution has a positive greenhouse gas input depends on:
- Temporal change in displacement value
- Cross-sector use of fossil carbon
- Degree substitution actually occurs
- The forest system supplying the wood
Concludes that the stated benefits of substitution are uncertain and unlikely to be as high as is commonly presented. RUNNING TIME 22:30 MINUTES
