With the Government of Quebec's strategy to increase the use of wood in the construction sector, the Charte du Bois is recognized as a government commitment in supporting Quebec's forest industry. It will lead to the increase of wood in this sector, so the supply of building materials will undergo changes and environmental consequences will follow. The environmental assessment of policies is important in order to improve the understanding of the consequences of our decisions. Currently, Life Cycle Assessment (LCA) approaches are incomplete in this regard.


The main goal of this ambitious research project is to develop a consequential LCA model to assess the environmental consequences of changes caused by an increase use of wood in the construction sector. 



The methods consist, first, in a review of the different methods of market modelling and material flows analysis, as well as different combination approaches in consequential LCA. This will enable the development of an appropriate approach for wood material in the construction sector. Finally, a case study will be defined to model the changes caused by a large introduction of wood in the construction sector and thus evaluate the environmental consequences.



The project will improve the environmental evaluation of public policies (such as the deployment of the Charte du Bois) through an implementation of a new type of LCA focused on the environmental consequences of changes. The study will also provide a better understanding of future environmental challenges in the building sector at the market level.
