Howmet Aerospace

Howmet Aerospace, a US-based air transport services company, is committed to reducing its carbon emissions. In 2025, the company's total emissions are projected to be approximately 2.37 billion kg CO2e, comprising approximately 400 million kg CO2e from Scope 1, 360 million kg CO2e from Scope 2 (market-based), and 1.61 billion kg CO2e from Scope 3 emissions.

Looking back, Howmet Aerospace reported total emissions of approximately 2.95 billion kg CO2e in 2024 (390 million kg CO2e Scope 1, 400 million kg CO2e Scope 2 market-based, and 1.78 billion kg CO2e Scope 3). In 2023, total emissions were around 3.09 billion kg CO2e, with 390 million kg CO2e from Scope 1, 460 million kg CO2e from Scope 2 market-based, and 2.24 billion kg CO2e from Scope 3.

Howmet Aerospace has set several climate commitments:

• Near-term targets:
  • The company aims for a 21.5% absolute reduction in combined Scope 1 and Scope 2 emissions by 2024, against a 2019 baseline year.
  • Howmet Aerospace has also committed to a 33.6% absolute reduction, or 339,952 metric tons, of combined Scope 1 and Scope 2 global greenhouse gas (GHG) emissions by 2027 from a 2019 baseline.
• Long-term targets: Howmet Aerospace is striving for net-zero emissions by the end of 2050, which necessitates an annual 4.2% contraction in emissions from its 2019 baseline.

Historically, the company achieved a 19.2% decrease in direct and indirect GHG emissions (Scope 1 and Scope 2) in 2020 compared to 2019.
