primary data

quantified value of a process (3.1.3.5) or an activity obtained from a direct measurement or a calculation based on direct measurements

Primary data need not necessarily originate from the product system (3.1.3.2) under study because primary data might relate to a different but comparable product system to that being studied.

Note 2

Primary data can include GHG emission factors (3.1.2.7) and/or GHG activity data (defined in ISO 14064-1:2006, 2.11).
