Technical Notes "Definition" "Consumption of HCFCs is the consumption of all Hydrochlorofluorocarbons (HCFCs) controlled by the Montreal Protocol and its amendments, measured in terms of their ozone-depleting potential." "" "Consumption means production plus imports minus exports of controlled HCFCs. Ozone-depleting potential is the amount of degradation to the ozone layer caused by a substance compared to trichlorofluoromethane (CFC-11), which was given an ozone-depleting potential rating of 1.0. The list of controlled HCFCs of the Montreal Protocol and its amendments is available at http://ozone.unep.org/Publications/MP_Handbook/Section_1.1_The_Montreal_Protocol/Annex_A.shtml. " "" "Years Covered and Frequency of Update" "Data are available here for the years 1986 and 1989-2007. The UNEP Ozone Secretariat updates the Data Access Centre continuously as annual country reports are submitted. " "" "Methodology" "Pursuant of the Montreal Protocol, countries are required to report annually on production and consumption of ozone depleting substances. The UNEP Ozone Secretariat attempts to assemble much of the information related to countries reporting of data and other information in a usable manner for countries as well as the general public. It should be noted that certain chemical specific data reported by countries is considered to be confidential. As a consequence, the data contained in the Data Access Centre is grouped according to the basket of chemicals covered in each grouping by the protocol. " "" "Data Reliability" "The data are presumed to be fairly reliable, however, due to variable reporting by countries and the rounding of numbers for presentability, the results of the queries may not yield definitive quantities relative to compliance.
