Kaiser Aluminum has published its 2025 Sustainability Report, highlighting the company’s sustainable business practices and initiatives.

The report (available here) reflects Kaiser’s commitment to its corporate values, which continue to guide how the company pursues sustainable value creation and form the foundation of its culture and strategy.

Keith A. Harvey, Chairman of the Board, President, and CEO of Kaiser Aluminium, said: “I’m proud of our team and the progress we achieved in 2025 as we advanced our strategy and strengthened the foundation of our business.

“Our values continued to guide our decisions and reinforce our commitment to operating responsibly, investing with discipline, and supporting the long-term sustainability of our operations.

“The completion of the most significant capital investment cycle in our recent history, combined with improved financial performance and continued progress toward our environmental goals, reflects the dedication of our people and our focus on creating lasting value for our customers, stockholders, and communities.”

Highlights from the report include:

  • Expansion of high-recycled-content product portfolio: the company introduced two new high-recycled-content products and commercialised alloy 6026A, which is fully compliant with the EU Restriction of Hazardous Substances directive.
  • Progress toward greenhouse gas emissions reduction goals: the company continued to advance its 2030 emissions intensity targets, achieving a combined Scope 1 and 2 emissions intensity that was 17% below the 2019 baseline. This progress reflects the first full year of the Warrick rolling mill operating on lower carbon grid power and ongoing efforts to expand high-recycled-content offerings.
  • Investment in people and talent development: the company expanded learning and development programmes designed to strengthen leadership capabilities, support employees at key career stages, and build a stronger manufacturing talent pipeline through growing partnerships with colleges and universities focused on skilled trades.
  • Ongoing commitment to community engagement: Throughout 2025, the company strengthened community partnerships through employee volunteerism, charitable sponsorships, and corporate giving, reflecting its commitment to being a responsible and valued community partner.

In addition, Kaiser Aluminum deployed $137 million in 2025 capital expenditures to support growth, modernisation, and operational excellence.
