Abstract: As the world moves towards a lower emission society to limit global warming to the 1.5oC target, we see that the end-markets for aluminium are influenced providing new market opportunities for the aluminium industry. In addition, we see an increasing number of end-user companies of aluminium also commit to limit their own emissions according to the 1.5oC target. Evidence of this is, for example, the Science Based Target Initiative (SBTi) that was set up by the United Nations, World Wildlife Fund, and the World Resource Institute after the Paris Accord to help companies to decarbonise. At the end of 2024 close to 10 000 companies worldwide have joined SBTi and are setting targets. SBTi not only require targets on own direct emissions, but also emissions from the supply chain.
We will discuss what impact these decarbonisation targets and strategies will have on the aluminium industry both from a market and supply chain perspectives. For example, we expect material and supplier selection will not only be based on the traditional functionality and cost, but also include sustainability targets. Furthermore, we will discuss carbon footprint of aluminium and roadmaps to decarbonise. Finally, we will point to strategies aluminium ingot and semi suppliers might adopt to create business opportunities based on end users’ decarbonisation targets.
