Low-Carbon Aluminium in Packaging: Carbon Footprint, Smelting Emissions, and Sourcing Guide

Low-carbon aluminium in packaging is becoming a procurement requirement as brands face Scope 3 reporting obligations. The article explains why the carbon problem starts at the smelter, where primary aluminium production can emit over 16 tonnes of CO2 per tonne when powered by fossil fuels. Switching to renewable electricity, increasing recycled content, and adopting inert anode technology are the three main pathways to lower emissions. The article also covers the lack of a universal definition for low-carbon aluminium and the different thresholds used by frameworks like the First Movers Coalition and Fastmarkets. Product Carbon Footprint (PCF) methodology aligned with ISO 14067 is emerging as the preferred measurement standard. For packaging buyers, understanding these metrics and verification requirements is essential for credible sourcing decisions.
