greenhouse gas emissions sources within the system boundary; greenhouse gas emission factors and calculation methodologies; life cycle inventory analysis; a base year and details of the organisation’s base year re-calculation policy; and the greenhouse gas emissions calculated as attributable to the life cycle of the product. Defining the including the system boundary The scope of the LCA report should include a description of: the product and its function; the functional unit; all assumptions made in the LCA; and the measurable parameters and system boundary of the product over its entire life The system boundary is best displayed as a flow chart (for example figure 2, ISO 14040:2006). An organisation should incorporate all relevant stages of the life cycle of the product in the LCA system boundary. Any decision to exclude life cycle stages, processes, inputs or outputs must be clearly stated, and the reasons for and implications of their exclusion justified. Setting a base year and base year re-calculation policy Organisations must set a base year to allow for their product’s emissions to be accurately compared over time, consistent with the steps outlined under 4.2.2. Chapter 14 of the GHG Protocol Product Standard provides additional guidance for product footprints: Setting Reduction Targets and Tracking Inventory Changes over Time. Emissions sources within the system boundary An organisation must consider all sources of greenhouse gas emissions within the system boundary of the product, including the relevant stages of the product’s life cycle. These may include: emissions resulting from the transformation, production, processing and acquisition of raw materials; emissions resulting from manufacture, production and final assembly;
