Abstract: A novel means of marketing the environmental attributes of renewable energy or emissions credits. By selling these attributes together with the item whose energy or emissions impact they neutralize, Mainstay Energy offers to make more concrete and compelling the value these attributes represent. The sale may take the form of: lifetime energy use displacement, a fixed period displacement, or a fixed period with renewals. These attributes exist for all forms of energy, including electricity, natural gas, gasoline, diesel fuel, and others, and we would like to protect against others using this “embedded attributes” approach with any of these energy types or emissions reductions credits.
