scope:

This Guideline establishes requirements and principles for undertaking comparative LCA studies of auto parts incorporating weight changes due to material composition, manufacturing technology, or part geometry, whether intended or not intended to be disclosed to the public.

This Guideline provides a framework for LCA of auto parts made of any material(s) and the effect of weight changes on use stage fuel consumption when comparing two or more design options.

Note: Examples of materials include metals, polymers, bio-based materials, or a combination of materials.

This Guideline applies only to auto parts used in vehicles with internal combustion engines (ICE), in accordance with Clause 5.2.

Notes:

(1) Internal combustion engine (ICE) is defined in Clause 3.

(2) Future editions of this Guideline might be expanded to any type of automobile.

This Guideline is intended for application in North America.
