This handbook was designed for small and medium sized enterprises (SMEs) to help them with their phase out efforts under the Montreal Protocol. It provides ways to eliminate or at least substantially reduce ODS use through illustration of case studies of specific SMEs who have succeeded using alternatives. It presents both technical and policy options that an SME can consider and eventually adopt for the long term, including resources and contacts that they can easily get in touch with. This publication is ideal for enterprises involved in refrigeration and air conditioning, foams, aerosols and solvents.
