Previously, methodologies approved by the CDM Executive Board were approved for use on ACR for the registration of projects in non-Annex 1 countries or for registration of projects in the U.S. after ACR review and approval of special applicability conditions. Under ACR Standard v7.0, CDM methodologies are no longer accepted for crediting new projects on ACR. Therefore, ACR’s approval of the Clean Development Mechanism’s methodology for Replacement of SF₆ with alternate cover gas in the magnesium industry, AM0065 Version 2.1, is withdrawn and the methodology is ineligible for crediting projects on ACR.
