1. This document contains the amendments adopted by the Executive Board of the clean development mechanism (CDM) (hereinafter referred to as the Board) at its eightieth meeting, to the Standard for sampling and surveys for CDM project activities and programme of activities (Sampling Standard) (v.04.1) (CDM-EB50-A30-STAN). The document will be consolidated in a revised version of the PS.
2. The entry into force of this document is with immediate effect.
1. The following paragraph shall read as follows:
10. Where there is no specific guidance in the applicable methodology, project proponents shall use 90/10 confidence/precision as the criteria for reliability of sampling efforts for small-scale project activities and 95/10 for large scale project activities.6 This reliability specification shall be applied to determine the sampling requirements for each individual parameter value determined through a sampling effort.7,8
8. If there is more than one parameter to be estimated in a CDM project activity, then a sample size calculation should be done for each of them. Then either the largest number for the sample size is chosen for the sampling effort with one common survey or the sampling effort and survey is repeated for each of the parameters. A random sub-sample within the common survey is allowed as long as: (i) the reliability specification (e.g. 90/10 confidence/precision for small-scale project activities and 95/10 for large-scale project activities) is achieved for each individual parameter, and (ii) the random sub-sample is consistent with the design of the survey and the corresponding sample size calculation.
2. The following paragraph shall read as follows:
20. Parameter values shall be estimated by sampling in accordance with the requirements in the applied methodology separately and independently for each of the CPAs included in a PoA except when a single sampling plan covering a group of CPAs19 is undertaken applying 95/10 confidence/precision20 for the sample size calculation. In the latter case the populations of all CPAs in the group are combined together, the sample size is determined and a single survey is undertaken to collect data (e.g. if the parameter of interest is the daily usage hours of light bulbs, it may be feasible to undertake a single sampling and survey effort spread across geographic regions of several CPAs when either homogeneity of included CPAs relative to the light usage hours can be demonstrated or the differences among the included CPAs is taken into account in the sample size calculation). Several groups of CPAs may be formed and sample sizes may be calculated for the groups. Currently PoAs applying large scale CDM methodologies are not included for applying single sampling plan covering a group of CPAs pending further analysis.
