Relevance Compilation Deinitions Ozone-depleting substance ODS

26 Indicator Protocols Set: EN IP © 2000-2011 GRI EN19 Emissions of ozone-depleting substances by weight.

1. Relevance

The ozone layer O 3 ilters out most of the sun’s biologically harmful ultraviolet UV-B radiation. The Montreal Protocol regulates the phase-out of ozone- depleting substances ODS internationally. Measuring ODS emissions enables an assessment of how well the reporting organization complies with current and future legislation, and its likely risks in this area. This is particularly relevant for organizations whose processes, products, and services have used ODS and must transition to new technologies in order to comply with phase-out commitments. The reporting organization’s results on ODS phase-out can help indicate its level of technology leadership and competitive position in markets for products and services afected by ODS rules.

2. Compilation

2.1 Ozone-depleting substances contained or emitted from products during their usage and disposal are not covered by this Indicator. 2.2 Emissions of substances covered in Annexes A, B, C, and E of the Montreal Protocol on Substances that Deplete the Ozone Layer are included. 2.3 Identify emissions of ozone-depleting substances using the following formulas: Emissions = Production + Imports- Exports of Substances Production = Substances Produced- Substances Destroyed by Technology- Substances used entirely as feedstock in the manufacture of other chemicals Note: ODS that is recycled and reused is not considered production. 2.4 Report the emissions of speciic ozone-depleting substances in tonnes and tonnes of CFC-11 equivalent.

3. Deinitions Ozone-depleting substance ODS

Any substance with an ozone depletion potential ODP greater than 0 that can deplete the stratospheric ozone layer. Most ozone-depleting substances are controlled under the Montreal Protocol and its amendments, and include CFCs, HCFCs, halons, and methyl bromide. CFC-11 equivalent CFC-11 is a measure used to compare various substances based on their relative ozone depletion potential. The reference level of 1 is the potential of CFC-11 and CFC-12 to cause ozone depletion.
