& fx.
nine ecofx levels::
one/ Check out the wiki to find the CO2 emissions and environmental impacts of some products (and services) that have already been estimated.
two/ To estimate the loss of natural habitat potential in square meters to make a product, multiply the kilograms of CO2 that are released to make the product by .8 (or 80%).
The ecofx calculator does the math super fast. >>
[In pounds to square feet.] To estimate the loss of natural habitat potential in square feet to make a product, multiply the pounds of CO2 released to make the product by 3.8 .
three/ If you don't know the CO2 emissions for a product, estimate it based on similar products from the ecofx card, the wiki or the short list on the left.
The CO2. section has some tips on how to estimate the CO2 emissions with the ecofx card, short list, lcacalculator.com, google and other tools.
four/ Print the ecofx card for some quick help when estimating the ecofx of a product or service. It has three ecofx formulas, and the CO2 emissions for some products.
five/ Sign the ecofx pledge that says, 'Before buying (or selling) a product or service, I pledge to estimate the ecological effects it has on natural habitat, on humankind, extinction and/or climate change, and then decide if the personal benefit outweighs the environmental impact.'
six/ To estimate the loss of plant and animal life potential in natural habitat to make the product multiply the kilograms [or pounds] of CO2 that are released to make a product by 2.4 .
seven/ To estimate how many of a product (if made) it would take to trigger 1 potential species extinction, divide 200,000,000 kilograms by the product's CO2 emissions in kilograms.
[In pounds.] Divide 429,000,000 pounds by the product's CO2 emissions in pounds.
eight/ If a product does not have a matrix yet, make one by using the formulas. Then share your matrix with others on the wiki and other websites.
nine/ Tell others about the ecofx of various products via Facebook, Wikipedia, shares, a story, your media and by wearing an XO (as the human and the planet).
footnotes::
a/ "Loss of natural habitat potential" is 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. This area in square meters is found by multiplying the number of kilograms of CO2 emissions of a product by .8 (80%). For non-metric, this area in square feet is found by multiplying the number of pounds of CO2 emissions of a product by 3.8. Based on the 'habitat, life, extinction formulas v2'.
b/ "Loss of plant and animal life potential 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. This weight is found by multiplying the CO2 emissions (either kilograms or pounds) of a product by 2.4 . Based on the 'habitat, life, extinction formulas v2'.
c/ "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. This trigger number is found by dividing 200,000,000 kilograms by the product's CO2 emissions in kilograms. For non-metric, divide 429,000,000 pounds by the product's CO2 emissions in pounds. Based on the 'habitat, life, extinction formulas v2'.
matrixes.
Use the ecofx matrixes to power up your consumer and business decisions for the planet -- such as the beer, automobile, airline flights, clothes dryer, shoes, t-shirt and denim pants matrixes at ecofx.org/wiki.Plus, anyone can use the habitat, life, extinction formulas v2 to make a new product or service matrix to add to the ecofx.org/wiki. For an Excel spreadsheet that does some of the math, download ecofxcalculatorV2.xls.

Formulas to estimate the loss of natural habitat potential, the loss of plant and animal life potential, and the extinction potential from producing, packaging, shipping and using a product, service, choice, or from extracting and utilizing a raw material. ----------- Step 1/ Determine the CO2 emissions of the product, service or choice. (CO2 emission estimates may be found via the company that offers the product, life cyle analysis done by a third party (via a web search), the lcacalculator.com, the ecofx.org 'short list' 'card' 'raw materials matrix' or 'ecofxcalculatorV2.xls spreadsheet', or other life cycle software. Step 2/ Multiply the CO2 emissions of the product in kilograms by .8 to estimate the loss of natural habitat potential in square meters. Multiply the CO2 emissions of the product in pounds by 3.8 to estimate the loss of natural habitat potential in square feet. Step 3/ Multiply the CO2 emissions of the product in kilograms by 2.4 to estimate the loss of plant and animal life in natural habitat potential in kilograms. Multiply the CO2 emissions of the product in pounds by 2.4 to estimate the loss of plant and animal life in natural habitat potential in pounds. Step 4/ Divide 200,000,000 kilograms by the product's CO2 emissions to estimate how many of the product (if made) it would take to trigger 1 potential species extinction. (To automate the math in these steps use the ecofxcalculatorV2.xls excel spreadsheet.) ----------- Formulas use "human appropriated net primary production (HANPP)" to "CO2 emissions" correlation.

_____________ column 1 _____________ The source of CO2 emisssions statistics (carbon dioxide footprint) may come from:: • The company that offers the product, service or raw material. • Life cyle analysis done by a third party. These can sometimes be found via a web search. • The online life cycle software at lcacalculator.com by IDC. • The 'ecofx short list', 'ecofx card' or the 'raw materials matrix' at ecofx.org. • The ecofxcalculatorV2.xls excel spreadsheet. • Life cycle software. The "loss of natural habitat potential" in m2 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 of 77 m2. For non-metric, the area of "potential natural habitat loss" in ft2 is calculated by multiplying the lb of CO2 emissions by the non-metric correlation factor of 3.78 . To automate the math, download the ecofxcalculatorV2.xls Excel spreadsheet. a) That the average global net primary productivity (NPP) per hectare equals the global NPP divided by the global 13.4 billion hectares of biologically productive land and water. b) That there is a substantial correlation between the global carbon dioxide emissions of humankind, and the amount of global bioproductivity that is depleted, harvested or managed for human use (i.e. human appropriated net primary production (HANPP)). c) That HANPP is a measure of the equivalent lost opportunity of natural habitat to maintain or establish itself. d) That there is a substantial correlation between the carbon dioxide emissions from making or using a specific product or service, and the amount of bioproductivity that is depleted, harvested or managed for human use from making or using the product or service, based on system infrastructure sharing and multiple use interdependence. (419,600,000,000,000 kg/ 134,000,000,000,000 m2 = 3.13 kg per 1 m2) Since 1 kg of CO2 emissions correlates to the loss of life in natural habitat potential of 2.4 kg of life as shown under the _column 5_ section below, we solve for 3.13 kg / 1 m2 = 2.4 kg/ ?m2. Therefore, ? = .77 m2. Therefore, the final correlation factor is .77 m2. That is, 1 kg of CO2 emissions correlates to the loss of habitat potential of .77 m2. The "hydrated" net primary production (NPP) of 419.6 gt was derived from the current "dry" NPP estimate of 104.9 giga-tonnes (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 long-term effects of climate change and persistent toxins. The correlation does estimate the loss of habitat potential in the current year based on HANPP. More info and forums regarding formulas are at ecofx.org. The weight of "loss of plant and animal life potential (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 in natural habitat" of 240 kg. For non-metric, the lb of "loss of life potential in natural habitat" in lb is calculated by multiplying the lb of CO2 emissions by the non-metric correlation factor of 2.4 . To automate the math, download the ecofxcalculatorV2.xls Excel spreadsheet. a) That there is a substantial correlation between the global carbon dioxide footprint of humankind, and the amount of global bioproductivity that is depleted, harvested or managed for human use [i.e. human appropriated net primary production (HANPP)]. b) That HANPP is a measure of the equivalent lost opportunity of natural habitat to maintain or establish itself. d) That there is a substantial correlation between the carbon dioxide emissions from making or using a specific product or service, and the amount of bioproductivity that is depleted, harvested or managed for human use from making or using the product or service, based on system infrastructure sharing and multiple use interdependence. 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 giga-tonnes (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. This correlation does not include the possible long-term effects of climate change and persistent toxins. The correlation does estimate the loss of plant and animal life potential (in natural habitat) in the current year based on HANPP. More info and forums regarding formulas are at ecofx.org. 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 non-metric, divide the 880 lb of CO2 emissions into 429,000,000 lb to get the extinction trigger of 487,500. a) That there is a substantial correlation between the global carbon dioxide footprint of humankind, and the number of estimated yearly extinctions. b) That there is a substantial correlation between the carbon dioxide emissions from making or using a specific product or service, and the degree to which extinction potential increases in that year, based on system infrastructure sharing and multiple use interdependence. 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) | ||||||
CO2.
Here are a few basic tips on how to estimate the CO2 emissions for a product using the ecofx card, the wiki or the short list.
First find a product on the ecofx card
, the wiki or the short list that is similar to (or the same as) the product you want to estimate the CO2 emissions for. Then estimate how many of the product -- from the ecofx card, the wiki or the short list -- it would take to equal the number or amount of product(s) you are estimating the CO2 emissions for. Then multiply that number by the CO2 emissions for the product from the ecofx card, the wiki or the short list.Then multiply the CO2 emissions you just got for the product by .8 to get the loss of natural habitat potential to make that product. Or, enter the CO2 emissions estimate for the product into the ecofx calculator and it will be calculated automatically.
Other good ways to find a product's CO2 emissions include the lcacalculator.com, the raw materials matrix, or a google search.
Once the CO2 emissions are found for a product using the above methods::
• Multiply the kilograms of CO2 that are released to make a product by .8 to estimate the loss of habitat potential in square meters to make the product. *
• For non-metric, multiply the pounds of CO2 released to make a product by 3.8 to estimate the loss of habitat potential in square feet to make the product. ] *
• Check out the habitat, life, extinction formulas v2 to estimate other ecofx too.
The *raw materials matrix* is included below for those who want to use it to calculate the CO2 emissions released to make a product or service.
Estimated carbon footprint, loss of habitat potential, loss of plant and animal life potential, and extinction potential to extract, produce and manufacture these raw materials into a product. ----------- Use this raw materials matrix to: • Compare the ecofx of various raw materials.• • Calculate the CO2 emissions for a product or service.• ( A faster online CO2 emissions calculator is at lcacalculator.com.) • To build a product matrix for the ecofx.org/wiki and beyond.• To use this matrix to estimate the CO2 emissions for a product, multiply the approximate weight of each of the materials used to manufacture and package the product by the appropriate numbers in column 3. Add the results together to get the total CO2 emissions. Then use the correlation factors to calculate the other ecofx for the product. For a spreadsheet that does some of the math download ecofxcalculatorV2.xls in excel. For CO2 emissions only use lca software or the lcacalculator.com . See footnotes for more. ----------- + CO2 emissions estimates come from lcacalculator.com. + + Except for CO2 emissions, estimates are based on habitat, life, extinction formulas v2. + (This matrix can be used to calculate other ecofx for a product, however, many find that it is usually easier to use the habitat, life, extinction formulas v2 once they have the CO2 emissions.) ----------- Formulas use "human appropriated net primary production (HANPP)" to "CO2 emissions" correlation. Estimates do not include the possible long-term effects of climate change and persistent toxins. ----------- 1 kg(kilogram) = 2.2 lb(pounds) 1 m2(square meter) = 10.8 ft2(square feet) 1 km(kilometers) = .62 mi(miles) 1 liter = .26 gallons | |||||

To calculate the CO2 emissions for a product using column 3, multiply the estimated weight of each of the materials used to manufacture and package the product, by the column 3 number that corresponds to the materials. Add the results together. For example, to calculate the CO2 emissions for a product that is made of 2 kg of ABS plastic and 3 kg of aluminum (virgin). First, multiply the 2 kg of ABS by 44 kg found in column 3 for ABS. That equals 88 kg of CO2 emissions for the ABS. Then, multiply the 3 kg of aluminum (virgin) by 80 kg found in column 3 for aluminum (virgin). That equals 240 kg of CO2 emissions for the aluminum (virgin). Finally, add the 88 kg to the 240 kg to get an estimate of 328 kg total CO2 emissions for the product. Once the product's CO2 emissions are known, the loss of habitat potential, loss of life potential and extinction trigger can be calculated by using the correlation factors. For example, for the product above, multiply the 328 kg of CO2 emissions by the metric correlation factor of .77 to get the loss of natural habitat potential of 253 m2. Then multiply the 328 kg of CO2 emissions by the metric correlation factor of 2.4 to get the loss of life potential in natural habitat of 787 kg. Then divide the 328 kg of CO2 emissions into 195,000,000 kg to get the extinction trigger of 594,512 (how many of the product triggers one potential extinction). | |||||
