European aluminium rolling and recycling company Speira has created a label, called Valis, for an independently verified carbon threshold.

The label marks products with a CO₂ footprint of less than 4 tonnes of CO₂e per tonne of aluminium.

It aims to provide a reliable basis for reporting, as well as enabling consistent, verifiable carbon accounting over time.

Cédric Rauhaus, Speira’s Head of Marketing, said: “With our new label Valis, we define a clear and independently verified carbon threshold.

“Every product carrying the label is backed by an Environmental Product Declaration and confirmed by an external authority.

“This means carbon performance you can document, report, and rely on.”

This process aims to ensure that the environmental data is accurate, and ready to be used for ESG reporting, audits, or customer requirements.

The verifications were carried out according to ISO 14025:2006 by Tetis Institute, a spin-off from the University of Genoa in Italy.

They cover all major cold- and hot-rolled, as well as coated, products from Speira’s Specialties.

These are primarily the alloys for transport applications and shipbuilding, for mechanical engineering and energy technology, and, most of all, for functional and aesthetic applications in architecture.

Generally, the declarations are an important tool for planners and engineers to compare the environmental impact of products in concrete terms and optimise the sustainability of their projects.

Additionally, in the construction sector in particular, sustainability standards such as BREEAM, LEED, and DGNB – voluntary certification systems for sustainable construction and operation – require EPDs.

Here, low-carbon aluminium from Speira can be used in façade elements as well as in roofing, window, and shading technology and, thus, contribute to “green buildings”.

Speira’s EPDs follow the cradle-to-gate approach and consider the use of primary metal, internal and external scrap, and alloy surcharges, as well as the composition, melting and casting, rolling and cutting.

The Life Cycle Assessments included were carried out by Alea Design, a spin-off from the University of Modena in Italy.
