Lifecycle assessment of a product is done keeping in mind mainly

Lifecycle assessment weighs a product's impacts from raw material to final disposal, keeping the end-of-life stage centrally in view.

Manufacturing is only one phase and does not capture the full cradle-to-grave picture.

Packaging is a narrow concern within the wider lifecycle.

Distribution covers transport but again forms just one segment of the whole.

Disposal decides how waste, recycling and pollution burden the environment at the end.

This whole-life view guides greener design and material choices.
