This report describes the environmental impacts by life cycle stage, as well as the total difference in impact of each comparison product to the baseline product. The life cycle stages included in this LCA study address the production of upstream materials and energy, product manufacturing, use, and the end-of-life treatment for all materials used throughout the life cycle. The report and the underlying methodologies and approaches have undergone external, independent critical review and fully comply with the requirements of the ISO 14040/14044 standards. The inventory and impact categories assessed are non-renewable primary energy demand, global warming potential, acidification potential, eutrophication potential, and smog potential. For detailed descriptions see Appendix A: Life Cycle Impact Assessment Categories.
