Long-term Sustainability of the Aluminium Industry

Aluminium’s unique combination of properties makes it a valued material across many end-use markets. Global demand for aluminium is expected to grow by 80% over the next 30 years. This growth reflects aluminium’s potential as a material that can enable sustainable development and provide solutions to global challenges. As societal expectations and momentum towards a more sustainable future builds, the aluminium industry must continue to adapt, minimising the impacts associated with production of the metal today while also developing technological pathways for the future.

The International Aluminium Institute has brought together its long-standing material flow analyses, life cycle analyses, waste management experience and industry statistics to provide a holistic view of the long-term sustainability of the industry. This presentation will: provide an overview of future demand scenarios for aluminium to 2050 and potential pathways for GHG reduction across the sector; and highlight opportunities to advance the technological developments that will be needed to meet growing demand whilst reducing environmental impacts.
