ODP  [ O ]  3 i ODP   i [ O FCKW ] 11 3 • Ozone layer depletion (ODP) is relative value that indicates the potential of a technology to decrease ozone layer • The Ozone Depletion Potential (ODP) defined as the ozone depletion produced by a unit of the gas converted into ozone depletion values produced by the reference substance trichlorofluoromethane (CCl 3 F = CFC-11) is the meter which is used to assess the importance of the effect produced by the various gases • During incineration wastes for energy, power plant generate dioxins, which have a negative impact on ozone layer

V i AP M  i AP i V SO 2 M SO 2 • Acid gases that are released into the air or resulting from the reaction of non-acid components of the emissions are taken up by atmospheric precipitations and the falling “ acid rain ” forms an acid input which is absorbed by plants, soil and surface waters • The Acidification Potential is a meter of the disposition of a unit of the mass of a component to release H + protones, compared to the reference substance SO 2

Conclusion • In presented data from GaBi software we can see that Ozone Depletion Potential of Slovakia is much lower than European Union avarage (EU27mix). The highes values are in biogas and waste. • In case of Acidification Potential Slovakia is above the EU avarage. The biggest share of AP is in technologies burning fossil fuels followed by biogas and biomas.
