This tool shows the environmental impact of delivering one cubic meter of kiln dried sawn lumber of the selected American hardwood species and thickness to the overseas customer using the specified transport route. The data is derived from an ISO conformant LCA model prepared using GABI software by Thinkstep. The eight environmental impact categories shown are a selection of those used in EN15804-conformant Environmental Product Declarations (EPDs) of construction products and are also being pilot tested for the EU’s Product Environmental Footprint (PEF) initiative.
