Zamak: The carbon footprint officially revised downward in the Ecoinvent database
A major update cuts previous emission estimates by a factor of three and confirms the material’s potential
The latest update of the Ecoinvent database corrects a long-standing injustice: due to the absence of published environmental data until now, zamak had been historically penalized by largely overestimated carbon figures. Long evaluated at around 2,400 kg of CO₂ per ton, this alloy—used in many products, including packaging—now displays a revised footprint below 671 kg according to the latest LCA data, representing a three- to four-fold reduction. This recalibration positions zamak as a sustainable and technically efficient option, particularly in comparison with aluminium and plastics, which often show values three to four times higher. Fully recyclable without loss of properties, zamak finally benefits from an accurate and fair assessment, allowing brands to compare their materials on reliable grounds and to steer their environmental strategies with greater precision.
