This indicator shows total consumption of ozone-depleting substances, expressed as values recalculated in accordance with the ozone-depleting potential (ODP) in tonnes per year. In methodological terms, the indicator is based on the standard issued by the European Environment Agency (IFC 4.1.b) – Consumption of ozone-depleting substances.

On the basis of annual reports made by liable persons according to current regulations, the EARS has maintained a database in recent years. A liable person is a client that has been issued a decision concerning annual imports and, at the same time, authorisation for each individual import of substances. Each year, liable persons are required to report to the EARS (MESPE) on the actual consumption of substances for the previous year. As the data are based on client reporting, cross-checking with other competent authorities (e.g. customs authorities) and the data collected by inspection services is useful for the purposes of verifying their accuracy. The processing of data provides an appropriate overview for comparison between the data collected by respective competent authorities as well as a basis for reporting to the UNEP Secretariat pursuant to the provisions of the Montreal Protocol. The data may be aggregated by type of consumed ozone-depleting substances (authorisations and reports) and recalculated into ODP tonnes (recalculated quantity in accordance with the ozone-depleting potential factor).
The data for 1989 are taken from the records kept at the Chamber of Commerce and Industry of Slovenia (Report on the State of the Environment 1995) – the only available data are those on total quantities of CFC, MFC, HCFC; there are no data concerning individual substances. For 1995, the data are taken from the Annual Yearbook RS (Statistical Office of the Republic of Slovenia). For the period 1997-2002, the data derive from annual reports communicated to the UNEP and prepared by the EARS on the basis of data from the above mentioned database.
It is impossible to draw a quantitative comparison with other countries, since each country’s index derives from the quantities in the base year and thereafter reduces consumption according to the recalculation of percentage shares of base quantities. The base year for Slovenia is 1986.
