References to case studies on alternatives to HCFCs

Introduction

This page provides links to case studies about non-HCFC alternatives for different applications. It is intended to help National Ozone Units access more technical details about commercially-available alternatives to replace or avoid HCFCs, which should be considered during the preparation of their countries' HCFC Phase out Management Plans (HPMPs).

This page is organised according to the same scheme as the corresponding Alternatives to HCFCs for new equipment and applications page. The source of the case study is indicated in partentheses after the title.

This page is a work in progress and UNEP welcomes the submission of additional case studies of commercially-available alternatives to HCFCs that should be considered for inclusion. Please inform the UNEP OzonAction programme, if you would like to suggest other case studies.
