The Subsidiary Body for Scientific and Technological Advice (SBSTA), at its fifteenth session, recalled decision 17/CP.5 entitled "Relationship between efforts to protect the stratospheric ozone layer and efforts to safeguard the global climate system" (FCCC/CP/1999/6/Add.1). The SBSTA further noted the information contained in document FCCC/SBSTA/1999/MISC.6 and Add.1 and 2 and also on the UNFCCC web site, and encouraged Parties included in Annex I to the Convention (Annex I Parties), the relevant bodies of the Montreal Protocol, the Intergovernmental Panel on Climate Change (IPCC), intergovernmental organizations and non-governmental organizations to update further the information on available and potential ways and means of limiting emissions of hydrofluorocarbons (HFCs) and perfluorocarbons (PFCs), including their use as replacements for ozone-depleting substances. The SBSTA also invited Parties to provide their views, by 1 March 2002, on information aspects noted in decision 17/CP.5 for compilation into a miscellaneous document (now available in FCCC/SBSTA/2002/MISC.6). The SBSTA requested the secretariat to prepare a document for consideration by the SBSTA at its sixteenth session, drawing upon information received by 1 March 2002 (FCCC/SBSTA/2001/8, para. 56)
