Life Cycle Assessment
Description of Declared or Functional Unit
Cut-off Criteria
This LCA is in compliance with the cutoff criteria specified in the PCR, as no known processes were excluded from
this assessment outside of the specific items listed within the “System Boundary” section below.
The functional unit represented here is a single lavatory including the associated packaging and accessories.
To express these impacts in terms of 1 metric ton of product, multiply each result by 47.4.
Allocation
Impacts are allocated to individual products with a unit process approach. Typically, product mass is used to build
the impact allocation factors. Product-specific quality data is also employed to match impacts to products.
Background Data
Primary manufacturing data was collected directly from Kohler Co. vitreous manufacturing operations for calendar
year 2013. Secondary (supply chain) data was taken from the U.S.-Ecoinvent v2.2 database.
year 2013. Secondary (supply chain) data was taken from the U.S.-Ecoinvent v2.2 database.
Data Quality
Primary manufacturing data was collected directly from process experts for the five Kohler vitreous plants within
North America. Wherever secondary data is used, the study adopts critically reviewed data for consistency,
precision and reproducibility to limit uncertainty. The data sources used are complete and representative of North
America in terms of the geographic and technological coverage and are a recent vintage (i.e., less than ten years
old). Any deviations from these initial data quality requirements for secondary data are documented in the critically
reviewed LCA report.
reviewed LCA report.
Secondary data primarily references the U.S.-ecoinvent v2.2 database. This database is widely distributed
throughout the United States and is referenced within the LCA community. All ecoinvent datasets have been
critically reviewed.
When a product is produced at more than one plant, impacts are weighted by unit volume to produce a single result.
