The analysis confirmed that 100 per cent of RUSAL's metal meets the low-carbon aluminium (LCA) benchmark of less than 4 t CO2/t within Scopes 1&2, aligning with benchmarks from leading international analytical agencies such as Fastmarkets and S&P Global. Additionally, in 2023, RUSAL improved the full-scope carbon footprint of its LCA brand ALLOW to 5.9 tons of CO2 equivalent per ton of metal, down from 6.1 tonnes the previous year.
This remarkable achievement is primarily due to the use of renewable energy sources, especially hydropower, to power RUSAL's production facilities and an extensive modernisation program for aluminium smelters. The program includes the renewal of electrolysers, transition to pre-baked anode technology, installation of new gas emissions treatment facilities, and improvements in air monitoring systems. In 2023 alone, RUSAL retrofitted 309 electrolysers across its smelters. The modernisation of alumina assets, which significantly contribute to the carbon footprint of the final product, is also a key focus.
RUSAL's ALLOW INERTA™ brand, featuring the lowest carbon footprint in the industry, is one of the frontrunners of RUSAL's decarbonisation efforts. Its cutting-edge production technology significantly reduces the total volume of greenhouse gas emissions during the electrolysis process. This solution allows for reducing carbon dioxide emissions within Scopes 1 and 2 to 0.01 tonnes of CO2 equivalent per tonne of aluminium (compared to the industry average of 11.4 tonnes of CO2 equivalent).
Increasing the recycled content in primary products is another critical component of RUSAL's decarbonisation strategy. A major milestone in this area is the production of primary equivalent foundry alloys (PEFA) with a 30 per cent share of secondary aluminium content, which has successfully launched and been delivered to its first customers.
