The measurement boundary refers to the extent of coverage when measuring the carbon footprint of a product. There are two common types of measurement boundaries:
Cradle-to-Grave: This covers the full product life cycle from resource extraction ('cradle') to the use phase and disposal phase ('grave').
Cradle-to-Gate: This covers the partial product life cycle from resource extraction (cradle) to the downstream transportation and storage (i.e., before it is purchased by the consumer).
