According to Wolf, an agreement in the form of a pro- tocol or other legal instrument can be expected in Kyoto later this year. Among other comments, Wolf said
47、 that when HCFC-22 is phased out in the next century, substitute refrigerants will be ready. Equipment for two alternatives is now being developed.
