Low-carbon aluminum
Primary aluminum with a carbon footprint that is one-third the industry average
EcoLum is primary aluminum with an emissions intensity1 that is one-third the industry average.2 Produced from smelters that use renewable energy and low carbon alumina sources, 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 is third-party verified and available to customers.3
- EcoLum primary unalloyed aluminium cradle-to-gate carbon footprint is 4.5 metric tons of CO2e per ton of metal, aligned with International Aluminium Institute (IAI) cradle-to-gate carbon footprint methodology and guidance
- Products can be offered with certification from ASI
- Verified according to ISO 14025, and life cycle analysis per ISO 14044
- Corporate greenhouse gas (GHG) inventory calculations is third-party verified and consistent with ISO 14064

Low-carbon alumina
Alumina products from a refinery portfolio with average emissions intensity less than half
of 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 is third-party verified and available to customers.3
- Products can be offered with certification from ASI
- Locations certified against international quality standard ISO 9001 and environmental standard ISO 14001
- Corporate greenhouse gas (GHG) inventory calculations is 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
