_____________ column 1 _____________ Product name, raw material name, details and/or the source of the CO2 emissions statistic. Other details such as the weight of the raw materials used in a product or service. The quantity of CO2 emissions from a product, a service or a raw material in kilograms and pounds. The source of CO2 emisssions statistics (carbon dioxide footprint) may come from:: "Loss of natural habitat potential" is used to describe an area of statistically typical land and/or ocean that could support a biodiverse ecosystem, but instead, is being currently used or depleted, or will be used or depleted by humankind within a current year, as a result of making or using a product or service. The "loss of natural habitat potential" in m^2 is calculated by multiplying the kg of "CO2 emissions" from making, packaging, shipping and/or using a product or service, by the metric correlation factor of .77 . For example, if a product has 100 kg of CO2 emissions, multiply the 100 kg of CO2 emissions by the metric correlation factor of .77 to get the loss of natural habitat potential for one year of 77 m^2. For nonmetric, the area of the "loss of natural habitat potential" in ft^2 is calculated by multiplying the lb of CO2 emissions by the nonmetric correlation factor of 3.78 . To automate the math, download the ecofxcalculatorV2.xls Excel spreadsheet. This correlation factor is based on these assumptions: (419,600,000,000,000 kg/ 134,000,000,000,000 m^2 = 3.13 kg per 1 m^2) Since 1 kg of CO2 emissions correlates to the loss of life in natural habitat potential for one year of 2.4 kg of life as shown under the _column 5_ section below, we solve for 3.13 kg / 1 m^2 = 2.4 kg/ ?m^2. Therefore, ? = .77 m^2. Therefore, the final correlation factor is .77 m^2. That is, 1 kg of CO2 emissions correlates to the loss of habitat potential for one year of .77 m^2. The "hydrated" net primary production (NPP) of 419.6 gt was derived from the current "dry" NPP estimate of 104.9 gigatonnes (gt) (Geider, 2001) of carbon per year. "Dry" NPP is the quantity of carbon that is turned into biomass by autotrophs per year in the Earth's biosphere. However, this "dry" NPP excludes the weight of the other minerals and water that normally comprise living biomass. Living organic matter is by weight about 50% carbon and 50% other minerals  excluding it water content. In total, most organic matter is by weight at least 50% water. Therefore, the NPP of 104.9 gt of carbon is multiplied by 2 to include the other minerals, and then multiplied by 2 again to include the water  resulting in 419.6 gt of "hydrated life". This correlation does not include the possible longterm effects of climate change and persistent toxins. The correlation does estimate the loss of habitat potential for one year in the current year based on HANPP. More info and forums regarding formulas are at ecofx.org. "Loss of plant and animal life potential for one year in natural habitat" is used to describe the weight of the life that could live in an area of statistically typical land and/or ocean that could support a biodiverse ecosystem, but instead, is being currently used or depleted, or will be used or depleted by humankind within a current year, as a result of making or using a product or service. The weight of "loss of plant and animal life potential for one year (in natural habitat)" in kg is calculated by multiplying the kg of "CO2 emissions" from making, packaging, shipping and/or using a product or service, by the correlation factor of 2.4 . For example, if a product has 100 kg of CO2 emissions, multiply the 100 kg of CO2 emissions by the metric correlation factor of 2.4 to get the "loss of life potential for one year in natural habitat" of 240 kg. For nonmetric, the lb of "loss of life potential for one year in natural habitat" in lb is calculated by multiplying the lb of CO2 emissions by the nonmetric correlation factor of 2.4 . To automate the math, download the ecofxcalculatorV2.xls Excel spreadsheet. This correlation factor is based on these assumptions: The correlation factor is found by:: Multiplying the weight of the global net primary production (NPP) of the land, by the percentage of human appropriated net primary production (HANPP) of the land, to get the weight of the HANPP of the land. Multiplying the weight of the global net primary production (NPP) of the oceans, by the percentage of human appropriated net primary production (HANPP) of the oceans, to get the weight of HANPP of the oceans. Adding the weight of the land HANPP to the ocean HANPP, and then dividing by the global output of carbon dioxide by humankind, to get average kg of CO2 per kg of HANPP. The result is the _column 5_ correlation factor. The 2007 NPP estimates 56.4 gigatonnes (gt) from terrestrial lifeforms per year, and 48.5 gt from ocean lifeforms per year  totaling 104.9 gt (Geider, 2001). Both the 56.4 gt and 48.5 gt are then multiplied by 4 to adjust these "dry" NPP carbon statistics from the research papers we have sourced to include the other minerals and water present in most living organic matter. This results in 225.6 gt of "hydrated" terrestrial life, and 194 gt of "hydrated" ocean life  totaling 419.6 gt. In other words, because dry organic matter is about 50% carbon and 50% other minerals, both the 56.4 gt and 48.5 gt are multiplied by 2. Also, because living organic matter is at least 50% water, they are multiplied by another 2.) A terrestrial HANPP percentage of 23.8% was sourced via Global human appropriation of net primary production by H Halberl et al. So, 23.8% x 225.6 gt = 53.7 gt of "hydrated" terrestrial life NPP. An ocean HANPP percentage of 6% that was estimated by Stele Ely is used because marine HANPP estimates have not been found in peer reviewed sources. This 6% is probably very low, and is loosely based on ...brave new ocean and other papers. Contact ecofx.org if you have a suggestion or comment. So, 6% x 194 gt = 11.6 gt of "hydrated" ocean life HANPP. Therefore, 53.7 gt + 11.6 gt = 65.3 gt of global "hydrated" HANPP life per year. Then, to get the correlation factor, the 65.3 gt of "hydrated" HANPP is divided by humankind's annual CO2 emissions of 27.25 gt. (65,300,000,000,000 kg / 27,250,000,000,000 kg = 2.4 kg of potential life loss per 1 kg of CO2.) In other words, 1 kg of CO2 corresponds to the loss of 2.4 kg of life potential in natural habitat for one year. This correlation does not include the possible longterm effects of climate change and persistent toxins. The correlation does estimate the loss of plant and animal life potential for one year (in natural habitat) in the current year based on HANPP.

"Trigger 1 potential species extinction" is used to describe how many of a product (if they are made) it would take to result in the release of the amount of CO2 emissions that correlates to one extinction in a current year  considering the CO2 emissions released by that product. The "trigger 1 species extinction" number is calculated by dividing the correlation factor of 195,000,000 kg, by the kilograms of "CO2 emissions" from making, packaging, shipping and/or using a product or material. For example, if a product has 400 kg of CO2 emissions, divide the 400 kg of CO2 emissions into 195,000,000 kg to get 487,500 of the product to trigger 1 potential species extinction. For nonmetric, divide the 880 lb of CO2 emissions into 429,000,000 lb to get the extinction trigger of 487,500. This correlation factor is based on this assumption: This correlation factor was determined by dividing the total global CO2 emissions of 27,245,758 tonnes of humankind in 2004 by an estimate of 140,000 species extinctions per year (Future of Biodiversity, L. Pimm). (27,250,000,000,000 kg / 140,000 extinctions = 195,000,000 kg of CO2 emissions per year per extinction)
