The National Research Council is continuing to develop its database. It's called a life cycle assessment database, and it includes all of the materials that are currently available for construction. That database will be the baseline that will be used starting in 2025 as we request a 20% reduction or a 10% reduction that would go to a 30% reduction of GHG in construction materials.
Currently, wood is not in that database. The only materials currently in that database, to my knowledge, are cement and concrete. Various materials in construction are continuing to be added, and as those materials are added it will benefit the reduction of GHG in construction. That's the innovation that's happening as part of the greening government strategy.
