Our carton packages are made of on average 70% paperboard from renewable wood fibres. For caps and plastic layers, we are increasing the use of plant-based plastic made from sugarcane. Renewable materials, such as paperboard made from wood fibres and plant-based plastic made from sugarcane, are better for the climate. They absorb CO2 in the atmosphere as they grow, and they are replenished naturally over time, as opposed to fossil-based materials that release new CO2, stored in the ground for millions of years.
To understand the environmental performance of our products, an important starting point is to base our decisions on knowledge and facts. One tool we use to find out about the climate and environmental impacts of our products is a Life Cycle Assessment (LCA).
A Life Cycle Assessment (LCA) is a method that measures the environmental impact of different products. It analyses each step of the value chain: energy use, the extraction of raw materials and its use, production, transportation, product handling, recycling, and end of life. LCAs ordered by Tetra Pak are conducted by independent researchers and are independently reviewed by an expert panel. An LCA gives insight into what the key issues are for us to address so we can improve the environmental performance of our products.
In the dairy chilled category, a third-party peer reviewed Life Cycle Assessment (LCA) shows that Tetra Pak® carton packages have between 73% and up to 81% lower climate impact than a plastic bottle*.
