GLOSSARYAcidification Potential(AP): phenomenon by which atmospheric rainfall has a pH which is lower thanaverage. This may cause damage in forests and cultivated fields, as well as in water ecosystems and objectsin general. This phenomenon is due to the emissions of SO2, of NOx, and NH3, which are included in theAcidification Potential (AP) index expressed in masses of H+ produced.Ozone Depletion Potential (ODP): degradation and depletion of the ozone layer in the stratosphere, whichhas the property of blocking the ultraviolet components of sunlight thanks to its particularly reactivecompounds, originated by chlorofluorocarbons (CFC) or by chlorofluoromethanes (CFM). The substanceused as a point of reference for assessing the ODP (Ozone Depletion Potential) is trichlorofluoromethane, orCFC-11.Global Warming Potential (GWP): phenomenon by which the infrared rays emitted by the earth’s surfaceare absorbed by the molecules in the atmosphere as a result of solar warming and then re-emitted in theform of heat, thus giving rise to a process of global warming of the atmosphere. The indicator used for thispurpose is GWP (Global Warming Potential). This mainly includes the emissions of carbon dioxide, the maingreenhouse gas, as well as other gases with a lower degree of absorption of infrared rays, such as methane(CH4), nitrogen protoxide (N2O), chlorofluorocarbons (CFC), which are expressed according to the degree ofabsorption of CO2 (g CO2 ).Eutrophication Potential (EP): enrichment of the watercourses by the addition of nutrients. This causesimbalance in water ecosystems due to the overdevelopment encouraged by the excessive presence ofnourishing substances. In particular, the Eutrophication Potential (EP) includes phosphorous and nitrogensalts and it is expressed in grams of oxygen (g O2).Photochemical Ozone Creation Potential (POCP): production of compounds which by the action of lightare capable of encouraging an oxidising reaction leading to the production of ozone in the troposphere. Theindicator POCP (Photochemical Ozone Creation Potential) includes especially VOC (volatile organiccompounds) and is expressed in grams of ethylene (g C2H4).13
