SIG has invested in physical PPAs that will secure enough renewable energy capacity to power all of its carton packaging production in Germany from January next year.

The physical PPAs encompass a combination of on-site solar installations, renewable electricity from on-shore wind turbines on a real-time supply basis, and a flexible top-up of hydropower.

This type of PPA involves the physical delivery of energy from assigned renewable power generators.

Arnold Schuhwerk, head of category polymers and energy global at SIG, said: “Securing physical renewable power for our carton packaging production is the highest attainable level of responsible energy sourcing”.

He added: “Alongside our growing global portfolio of on-site solar installations, we see power purchase agreements as the most sustainable way to directly invest in renewable energy capacity”.

The company claims that its investments in renewable energy for carton packaging production have already avoided over half a million tonnes of CO₂ equivalents. This is one of the ways in which SIG says it is working to cut greenhouse gas emissions from its operations and value chain as part of its ‘Climate+’ ambition.
