We will enhance the sustainability performance of our products through development of innovative and eco-responsible offerings and provide customers with verified sustainability performance data. By doing so, we aim to improve their environmental footprint and contribute positively to a more circular industry approach to aluminium.
- Life-cycle assessment (LCA) pre-study conducted, which will serve as the foundation for how to achieve verified sustainability information on Gränges’ products starting from 2020.
- 62 per cent (44) of product development projects were assessed to lead to improved climate performance for Gränges’ customers.
Aluminium as the “green metal”
Thanks to aluminium’s lightweighting properties and its recyclability, customers and end users can improve resource efficiency and climate performance by enabling less, longer and smarter usage of materials. Less usage because of aluminium’s light weight and its recyclability; longer usage due to its high corrosion resistance and durability; and smarter usage due to its versatility and impermeability. Aluminium is often called the “green metal” because of these properties which support a resource efficient society.
A study* from 2016 concluded that lightweighting of transport vehicles leads to substantial fuel and carbon emissions savings. The potential lifetime saving for a passenger car was estimated at 500 kg to 2,000 kg of carbon dioxide per 100 kg weight reduction.
Developing products that can increase customers’ sustainability performance and reduce their environmental footprint is a top priority at Gränges. Incorporating sustainability into product development expands the scope of sustainability considerations beyond production processes to the entire life-cycle of the products. The biggest opportunities for improving products’ sustainability performance is in the early stages of the product development process, when the product characteristics are decided. Gränges for example works to develop products that are based on more recycled aluminium and which improve energy efficiency in the usage phase.
Life-cycle sustainability performance
In 2019, Gränges continued to prepare for assessing and declaring its products’ sustainability impact to help customers make fact-based sustainability evaluations of Gränges’ products and to improve products’ sustainability performance.
The company conducted a life-cycle assessment (LCA) pre-study in the operations in Europe. In line with the prestudy, Gränges plans to build its declarations on LCA methodology in accordance with ISO 14040 and ISO 14044. Results from the pre-study confirmed that alloys based on a high share of recycled aluminium had a significantly lower carbon footprint and that the raw materials contributed to most of the carbon footprint, even for alloys based on a high share of recycled aluminium.
From 2020, Gränges plans to start communicating products’ sustainability performance as a first step towards the 2025 target that 80 per cent of its products should have verified sustainability information available.
