Yes, Mr. Chair. It is true that there is a fairly robust body of evidence that compares wood against other materials on what is usually called a life-cycle basis, meaning that you look at building a particular structure out of different materials—concrete, steel, wood—and you look at the total life-cycle environmental impact. From taking the raw material to producing the building product, transporting it to the site, construction, building life, to end of use disposal, you look at the entire life cycle of the product and what the greenhouse gas and environmental footprint associated with different building techniques is.
There's been a lot of analysis done along those lines, and it shows pretty consistently that wood has a lighter greenhouse gas and environmental footprint than other types of building materials.
We certainly are aware of this research and have been partners with different organizations and agencies conducting it over the years. And it is particularly in the international marketing of wood, where we're trying to encourage people, who don't have a deep culture of building with wood, that it is something they should consider. The environmental benefits and the green building benefits of wood, particularly wood from sustainably managed forests, is a major selling point in markets like China.
