Recognizing the opportunity to facilitate a clean production approach to the manufacture of hydrochlorofluorocarbon-22 ( HCFC-22 ) for both controlled and feedstock uses , Recalling decision XVIII/12 , in which the parties requested the Ozone Secretariat to facilitate consultations by the Technology and Economic Assessment Panel with relevant organizations to enable the Panel to draw on the work already carried out under those organizations , including work relating to HCFC22 , Recalling also the report of the Panel submitted pursuant to decision XVIII/12 , in particular the section on the role of the Clean Development Mechanism of the Kyoto Protocol to the United Nations Framework Convention on Climate Change with respect to hydrofluorocarbon-23 ( HFC-23 ) by-product emissions resulting from the production of HCFC22 , Recognizing the relationship of HFC-23 to the controlled substance HCFC-22 , given that the production of HCFC-22 results in the by-production of emissions of HFC-23 and that the production of HCFC-22 for feedstock uses is expected to continue beyond the phase-out of production for uses controlled under the Montreal Protocol ,
