ISO 14067

ISO 14067 is the international standard that sets out how to quantify and report the carbon footprint of a product.

It builds on the life cycle assessment standards ISO 14040 and ISO 14044, and covers the goal and scope of a study, the boundary, data, allocation, how to treat carbon from plants and land use, and what a report must contain.

Following it is a way of working, not a certificate. A footprint can follow ISO 14067 without anyone having checked it; the report should say whether it has been independently reviewed.
