Low-carbon aluminum
Primary aluminum with a carbon footprint that is 3 times better than the industry average
EcoLum™ is primary aluminum with an emissions intensity1 that is 3 times better than the industry average.2 Produced from smelters that use renewable energy, EcoLum™ is offered in a full range of products, including billet, foundry, slab, wire rod, unalloyed high purity, and P1020.
- EcoLum™ primary aluminum is produced with less than 4.0 metric tons of CO2e for every ton of metal, including both direct and indirect (Scope 1 and Scope 2) emissions from mining, refining, smelting and casting
- Cradle-to-gate carbon footprint data,3 third-party verified, available to customers
- Products can be offered with certification from the Aluminium Stewardship Initiative
- Verified according to ISO 14025, and life cycle analysis per ISO 14044
- Corporate (GHG) inventory calculations third-party verified and consistent with ISO 14064

Low-carbon alumina
Alumina products from a refinery portfolio with average emissions intensity two times better
than the industry average2
The world's only low-carbon alumina brand, EcoSource™, is delivered from a refinery portfolio with an average emissions intensity that is no more than 0.6 metric tons of carbon dioxide equivalents per ton of alumina produced, including both direct and indirect (Scope 1 and Scope 2) emissions from bauxite mining and alumina refining. Leveraging Alcoa's mine-to-refinery advantage, this emission intensity is less than half of the global industry average.2
- Available as smelter-grade (SGA)and certain non-metallurgical (NMA) grades
- Cradle-to-gate carbon footprint data, third-party verified, available to customers
- Products can be offered with certification from the Aluminium Stewardship Initiative
- Locations certified against international quality standard ISO 9001 and environmental standard ISO 14001
- Corporate greenhouse gas (GHG) inventory calculations third-party verified and consistent with ISO 14064

Aluminum with recycled content
Aluminum with at least 50 percent recycled content, supporting the circular economy
Aluminum's status as a nearly infinitely recyclable metal makes it a key enabler of the circular economy. EcoDura™ contains at least 50 percent recycled content,4 conserving significant amounts of energy and reducing the environmental impacts associated with producing virgin aluminum. EcoDura™ is manufactured in North America and Europe, using clean scrap from verified sources and is available to customers globally.
- EcoDura™ locations are ISO 9001 certified
- The product can contribute to LEED® certification points for sustainable building and construction projects
