Our goal is to make all of our packages from 100 percent renewable materials. Already, our cartons made mostly from plant-based materials have a significantly lower climate impact than packages made from fossil or mineral sources. The lifetime carbon impact of a Tetra Recart food package, for example, is five times less than its steel or glass equivalent. With renewable materials, products can also have positive environmental, economic and social impacts, capturing carbon as well as reducing emissions during their lifecycle, and promoting sustainable land use and biodiversity.

On average more than 70 percent of a Tetra Pak carton by weight is paperboard. This, along with plant-based polymers, present in caps and sleeves, significantly increases the share of materials from renewable sources in a package. This share is determined by summing the weight of both materials and dividing it with the weight of the package.
Additives, such as the printing ink and the pigment giving color to the cap, represent a minor part of the package weight (typically <1%), and are disregarded in the calculation of the share of renewable material.
The use of renewable materials that are continuously replenished, such as wood fibre from trees or bio-based plastic from sugarcane, plays an important role in reducing resource scarcity and mitigating climate change.
