The Clean Development Mechanism was established in the Kyoto Protocol (1997) to help countries achieve their emission reduction targets. The CDM “requires the application of a baseline and monitoring methodology to determine the amount of Certified Emissions Reductions (CERs) generated by a mitigation CDM project activity in a host country.” CDM methodologies consist of five categories for its project activities: large-scale; small-scale; large-scale afforestation and reforestation (A/R); small-scale A/R; and carbon capture and storage (CCS) project activities.
As of March 16, 2022, there are one hundred approved small-scale methodologies (UNFCCC, 2022). This paper of 5 sections provides a summary of selected revisions (from version 18.0. to version 14.0.), to a small-scale Clean Development Mechanism (CDM) methodology “AMS-I.A.: “Electricity generation by the user” (hereinafter referred to as “AMS-I.A.”).
