GLOSSARY———————————————————————————————————————————————————————Acidification Potential (AP)Phenomenon by which atmospheric rainfall has a lower pH. This may cause damage to forests and crops, as wellas to water ecosystems and objects in general. This phenomenon is due to the emissions of SO 2, NOx, and NH 3,which are included in the Acidification Potential (AP) index expressed in masses of H+ produced.Ozone Depletion Potential (ODP)Degradation and depletion of the ozone layer of the stratosphere, which has the property of blocking the ultravioletcomponents of sunlight thanks to its particularly reactive compounds, originated by chlorofluorocarbons (CFC) or bychlorofluoromethane (CFM).The substance used as an indicator for assessing the ODP (Ozone Depletion Potential) is trichlorofluoromethaneor CFC-11.Global Warming Potential (GWP)Phenomenon by which the infrared rays emitted by the Earth’s surface are absorbed by the molecules in theatmosphere as a result of solar warming: and then re-emitted in the form of heat, increasing the process rate ofatmospheric global warming. The indicator used for this purpose is GWP (Global Warming Potential). This mainlyincludes the emissions of carbon dioxide, the main greenhouse gas, as well as other gases that lead to infrared rayabsorption, such as methane (CH 4), nitrogen protoxide (N 2O), chlorofluorocarbons (CFC), which are expressedaccording to the degree of absorption of CO 2. The potential is calculated on a mass basis for the time horizon 100years – (g CO 2-equivalents).Eutrophication Potential (EP)Enrichment of the watercourses by the addition of nutrients. This causes imbalance in water ecosystems due tooverdevelopment stimulated by the excessive presence of nourishing substances. In particular, the EutrophicationPotential (EP) includes phosphorous and nitrogen salts and is expressed in grams of oxygen (g O 2).Photochemical Ozone Creation Potential (POCP)Production of compounds that are capable of stimulating an oxidizing reaction due to the action of light, leadingto the production of ozone in the troposphere. The indicator POCP (Photochemical Ozone Creation Potential)especially includes VOC (volatile organic compounds) and is expressed in grams of ethylene (g C 2H 4).Total Energy ConsumptionIs the overall amount of energy involved in a production system. This is the energy used when all materials and fuelsare traced back to the extraction of raw materials from the earth and is a measure of the total energy resource thatmust be extracted from the earth in order to support the system.18
