Key Findings

01Product displacement factors for sawnwood and panels were 0.54 tC displaced per tC of use and 0.45 tC displaced per tC of use, respectively.
02Energy displacement factors for bioenergy ranged from 0.47 tC displaced per tC of use (constant supply) to 0.89 tC displaced per tC of use (constrained supply).
03The greatest avoided emissions occurred when wood substituted for steel and concrete in buildings, and when bioenergy displaced high-emission fossil fuels.

Method & Evidence

AimTo quantify the greenhouse gas (GHG) mitigation benefits of wood product substitution and bioenergy use at a national scale in Canada.

MethodLife-cycle assessment and displacement factor analysis

ProcedureThe study compiled end-use wood products and calculated emission reductions from substituting wood-intensive products with less wood-intensive alternatives. It also analyzed bioenergy feedstock scenarios to determine displacement factors for displacing fossil fuels. Avoided emissions were weighted by Canadian consumption statistics.

ContextNational-scale climate change mitigation analysis for Canada, focusing on the forest sector and its products.

Strengths & Limitations

Strengths

+National-scale analysis provides broad applicability for policy and large-scale design.
+Quantifies specific displacement factors for different applications.

Limitations

The displacement factors are national averages and may not perfectly reflect local conditions or specific product applications.

Reliability & validity

The study's reliability is supported by its use of established life-cycle assessment methodologies and national consumption data. Validity is enhanced by considering multiple scenarios and product types, though the national scale may limit direct applicability to highly specific local contexts.

Think critically

How might the 'constrained supply' scenario for bioenergy impact its long-term viability and scalability as a climate mitigation strategy?

Paragraph starter

The research by Smyth et al. (2016) quantifies the significant greenhouse gas mitigation potential of wood products and bioenergy. Their findings indicate that substituting wood for steel and concrete in construction, and using bioenergy to displace fossil fuels, can lead to substantial carbon emission reductions, with displacement factors as high as 0.89 tC per tC of bioenergy used. This underscores the environmental advantages of incorporating sustainable forest-derived materials and renewable energy sources into design projects.
