Alcoa

Aluminium and aluminium products producer Alcoa, headquartered in the US, reported global Scope 1 emissions of approximately 15.16 billion kg CO2e and Scope 2 (market-based) emissions of approximately 10.52 billion kg CO2e in 2025. Their Scope 1 and 2 (market-based) emissions combined for 2025 were approximately 25.68 billion kg CO2e. For 2024, they reported Scope 1 emissions of approximately 15.57 billion kg CO2e and Scope 2 (location-based) emissions of approximately 4.44 billion kg CO2e, with combined Scope 1 and 2 (location-based) emissions of approximately 20.01 billion kg CO2e.

Alcoa has set an ambition to achieve net-zero Scope 1 and Scope 2 greenhouse gas emissions across its global operations by 2050. Interim intensity targets include a 30% reduction in GHG emission intensity from refining and smelting (Scope 1 and Scope 2) by 2025 and a 50% reduction by 2030, both against a 2015 baseline. They have also committed to aligning their GHG (Scope 1 and 2) emissions reduction targets with the 'well below 2°C' pathway by reducing GHG emission intensity by 50% by 2030 from a 2015 baseline.

In 2020, Alcoa reported its most comprehensive emissions data, including Scope 3, with total emissions of approximately 64.01 billion kg CO2e. This included Scope 1 emissions of approximately 18.5 billion kg CO2e, Scope 2 (location-based) emissions of approximately 5.4 billion kg CO2e, and Scope 3 emissions of approximately 40.64 billion kg CO2e. Key Scope 3 categories in 2020 included processing of sold products (approximately 34.12 billion kg CO2e), purchased goods and services (approximately 3.91 billion kg CO2e), and fuel and energy-related activities (approximately 1.34 billion kg CO2e).
