21. Information and data for the inventory of the carbon in living aerial biomass, dead biomass and, where applicable, the soil must be gathered at the following times:(1) in the case of an early project, at the same time as the activities needed to ensure completeness at the project filing stage in order to determine the initial carbon stock in the reservoirs of the lot or part of a lot for the project and of the equivalent lot and thereby establish the starting point for the simulation of the baseline scenario and project scenario provided for in Chapter IV of this Title; or
(2) in other cases, before any site preparation work to plant seedlings or sow seeds in order to determine the initial carbon stock in the reservoirs of the lot or part of a lot for the project and thereby establish the starting point for the simulation of the baseline scenario and project scenario provided for in Chapter IV of this Title; and
(3) at the end of each reporting period, within the meaning of section 2, in order to determine annual changes in the carbon stock in the reservoirs of the lot or part of a lot used for the project during that period and then to calculate the project outcome as provided for in Chapter VIII of this Title, using data from the report generated by the CBM-CFS software;
(4) all measuring and other equipment used for the inventory of the lot or part of a lot for the project pursuant to this Chapter must be used in accordance with the manufacturer’s instructions, be maintained in good working order and work reliably when used.
