Lightweight, durable, recyclable aluminium part of a sustainable future


London, UK. As the world comes together in Paris to develop a plan of action to tackle the most significant sustainability challenge of the age, the International Aluminium Institute looks forward to a new international agreement on climate change.

Delivering improved quality of life for all, equitable access to resources and services, food security, mobility and urban development, in a carbon and labour constrained world requires innovative use of materials, with the potential to deliver more for less.

On a full life cycle basis, across its wide range of commonplace applications, aluminium products provide a net benefit to society and to emissions reduction. From transportation, building and construction to food and medical/pharmaceutical packaging, aluminium plays a critical role in both short- and long-life applications.

Reductions in vehicle and cargo/goods container weight across transport modes allows for greater efficiency and reduced energy consumption. Aluminium packaging protects the energy, water and resources invested in producing, growing and processing food. It also ensures the additional energy used to get that food to us - in transport, retailing, shopping, storing and cooking - is not wasted. Efficient, low loss aluminium cabling is bringing power to more and more communities and the use of aluminium in renewable energy generation, transmission and intelligent control systems is increasing.

Three quarters of the 1 billion tonnes of aluminium ever produced is still in productive use. A positive recycling story and of demand for light, strong, conductive, protective products and the durability of many of the aluminium applications. Much of the aluminium in long lifetime applications has not yet reached the end of the "first life", but will remain available for future recycling. Long lifetime products tend to have high recycling rates, greater than 90%.

The use of 1 kg of aluminium to lightweight a car or light truck can save a net 20 kg of CO2 over the life of the vehicle. This figure is even higher for more weight sensitive applications (for instance, up to 80 kg CO2 per kg of aluminium used in trains). The 20+ million tonnes of aluminium used in transport today could save 400 million tonnes CO2 and over 100 billion litres of crude oil over the vehicles' lives.

Depending on the source of electricity used in the electrolysis (smelting) stage of production, the aluminium greenhouse emissions footprint can be as low as 4kg CO2-e per kg of aluminium ingot (from renewable energy), with a global average of 12kg CO2-e per kg of aluminium ingot for all energy sources.

The International Aluminium Institute, through its Aluminium for Future Generations (www.world-aluminium.org) and Aluminium Story (www.thealuminiumstory.com) programmes collects and publishes transparent, timely and representative data on the global industry's sustainability performance, in order to demonstrate that:
•       it produces responsibly, by mitigating environmental impacts and contributing to the communities where it operates
•       its products bring a net benefit to society through reduced environmental impact; improved quality of life, health, safety & wellness and economic growth;
•       at the end of product life, the value of the metal, the energy and resource inputs used in its production are retained and realised as other products, through collection and recycling or energy recovery.




NOTES

The IAI is the global forum of the world's aluminium producers, representing over 60% of global bauxite, alumina and aluminium production. The key objectives of the Institute are to:

- Increase the market for aluminium by enhancing world-wide awareness of its unique and valuable qualities.
- Provide the global forum for aluminium producers on matters of common concern and liaising with regional and national aluminium associations to achieve efficient and cost effective co-operation.
- Identify issues of relevance to the production, use and recycling of aluminium and promoting appropriate research and other action concerning them.
- Encourage and assisting continuous progress in the healthy, safe and environmentally sound production of aluminium.
- Collect statistical and other relevant information and communicating it to the industry and its principle stakeholders.
- Communicate the views and positions of the aluminium industry to international agencies and other relevant parties.

Through the IAI, the aluminium industry aims to promote a wider understanding of its activities and demonstrate both its responsibility in producing the metal and the potential benefits to be realised through their use in sustainable applications and through recycling.
