Dow and Amcor announced a collaboration that pairs Dow's low carbon polyethylene with Dow's Carbon Footprint Ledger. The goal is to help brands and retailers measure emissions tied to packaging materials. Dow brings the resin and carbon accounting method, while Amcor handles design and manufacturing. The companies have not named specific packaging applications, participating customers, or emissions reduction targets. No timeline or comparative life cycle assessment was provided. Dow says the ledger uses mass balance accounting and is checked against ISO 14067 and the Greenhouse Gas Protocol Product Standard, though the assurance provider is not identified. Packaging emissions are often a major part of Scope 3 for consumer goods companies. That makes this worth tracking, but the missing detail means the real test will come when actual products and verified footprint data are published.
