Figure 1: Schematic overview of the product life cycle of a lubricant or other speciality. * (inbound)-gate-to-(outbound)-gate might contain more life cycle stages, up to the raw material acquisition phase, e.g. for integrated companies. The bars are for visualisation purposes only and do not represent physical boundaries.
The cradle-to-(outbound)-gate (partial) PCF includes the following emission sources (cf. Figure 1):
• The cradle-to-(inbound)-gate scope includes all GHG emissions resulting from the production, transport, and packaging of purchased raw materials required for the manufacturing of the product described by the declared unit.
• For the assessment of the emissions resulting from (inbound)-gate-to- (outbound)-gate activities, the lubricant manufacturer collects internally related input- and output data based on primary data for each operational site. Where collection of primary data is not practicable, secondary data can be used for inputs and outputs (see ISO 14067 Section 6.3.5). The manufacturer calculates the gate-to-gate GHG emission based on these data:
o (inbound)-gate-to-(outbound)-gate: ▪ summarizing all gate-to-gate GHG emissions originating from operations (production, storage and transport) in the plants producing or storing the product.
▪ summarizing all GHG emissions resulting from the production of energy purchased by the lubricant manufacturer energy purchases.
▪ summarizing indirect emissions, directly related to (inbound)- gate-to-(outbound)-gate activities.
The GHG Protocol “Scope” terminology iswidely used for Corporate Carbon Footprint (CCF) reporting and is applied and known in the industry. Therefore, an example for a product system of stereotypical lubricant manufacturers including the Scope terminology is provided to enhance the understanding (cf. Figure 2).
