GREENHOUSE GAS (GHG) EMISSIONS
Carpenter Technology is committed to protecting the environment and minimizing our impact through a managed sustainability program. You can learn about our environmental sustainability program through our public disclosures, including our annual Sustainability Reports, our Sustainability Accounting Standards Board (SASB) report, and our Task Force on Climate-related Financial Disclosures (TCFD) report.
The EHSS team oversees Carpenter Technology’s environmental management system and develops policies and protocols that establish our global standards for energy management and GHG emissions, air emissions, waste, water, scrap metal recycling, sustainable sourcing, safety standards, and training. The EHSS team also supports compliance with applicable legal and regulatory requirements and alignment with best practices.
The majority of Carpenter Technology’s manufacturing facilities are ISO14001 certified. These facilities generate over 90% of our business.
Risks: Carbon pricing relevant to facilities and products, mandates and regulations affecting existing products and services, shifts in customer preferences, and extreme-weather events that could disrupt the supply chain.
Opportunities: Growth through sustainable products and markets, improved operational performance through increased efficiency, and support for customers navigating the transition to a lower-carbon economy.
Climate: Reduce GHG emissions
Energy: Reduce energy intensity
Water: Reduce fresh water intensity
Waste: Reduce and recycle waste
Air Emissions: Reduce air pollution emissions
Air Emissions: Reduce air pollution emissions
Sustainable Sourcing: Source materials sustainably
Specialty alloy manufacturing is energy intensive, primarily using electricity and natural gas to melt and process materials. Carpenter Technology actively monitors energy consumption across its operations and seeks opportunities to improve efficiency, reduce waste, and optimize manufacturing processes while meeting customer and operational requirements.
In 2025, energy intensity marginally increased to 79 GJ per metric ton shipped. We continue to review energy performance at the site and corporate levels, share best practices, and identify operational improvements as we work toward our goal of reducing energy intensity 5% from the 2019 baseline.
Water use and management is an important component of our manufacturing process, as water is used to cool material at specified rates.
We look to implement best practices in water use, including:
We manage wastewater discharge in accordance with the National Pollutant Discharge Elimination System Permits implemented by the U.S. Environmental Protection Agency (EPA). All sites conduct routine monitoring of treated wastewaters and stormwaters through sampling and analysis to ensure compliance with respective permits and limits.
Carpenter Technology also uses the WRI Aqueduct Water Risk Atlas to identify facilities located in areas of elevated water stress.
Water consumed is the difference between total water used and water discharged over the course of the calendar year.
By preventing waste in our manufacturing processes, we can reduce environmental risk and operational costs. We track the amounts and types of waste generated by each facility and review audits of our third-party waste management partners.
In addition to waste reduction, we reuse, recycle, or recirculate as many byproducts as possible. In 2025:
Our waste management approach ensures that all waste, including hazardous and nonhazardous waste, is disposed of in compliance with national and international waste management requirements, including the EPA's Resource Conservation and Recovery Act (RCRA) and the EU’s Restriction of Hazardous Substances Directive (RoHS). We dispose of waste at approved Treatment, Storage, or Disposal Facilities (TSDFs) that have obtained proper environmental permits for disposal. Also, we encourage recycling office waste, including e-waste which is handled by our IT department to ensure it is done properly.
We had zero reportable spills in 2025. At our facilities, we train our employees on emergency procedures and how to respond in the event of a spill.
We closely monitor and report air emissions from our major manufacturing sites. All air emissions data can be found in our latest SASB table.
All manufacturing facilities strictly comply with applicable regulatory requirements regarding emissions limits and hold valid air permits. We have implemented measures to reduce emissions, including dust, mist, and fume pollution capture and control systems, and efficiency is always a consideration during equipment repair and upgrades.
Carpenter Technology does not operate in areas of high biodiversity risk or in areas with critical habitats, as identified and defined by scientific and conservation organizations such as IUCN and UNEP-WCMC. In addition, the company does not engage in activity associated with land disturbance or tailing ponds. Because our operations do not pose a significant risk to biodiversity, the topic does not reach the threshold of materiality in comparison to other operational areas.
Nonetheless, Carpenter Technology manages biodiversity responsibly and in accordance with applicable laws and regulations and will continue to assess and monitor the impact of our operations on biodiversity. We continue to manage areas within our sustainability program that overlap with considerations in biodiversity such as greenhouse gas emission reduction activities, air emission management, and water management.
We are committed to conducting our business in an ethical, legal, and socially responsible manner. We expect our suppliers, customers, and vendors around the world to operate in line with the values outlined in our Code of Business Conduct and Ethics, Human Rights Policy, and Supplier Code of Conduct.
Carpenter Technology is proud to create products that contain as much recycled or reclaimed material as possible. We rely heavily on the use of reclaimed metal in our production of highly specialized metal alloys to reduce the need to procure carbon-intensive inputs:
We are committed to finding more ways to incorporate recycled scrap into our operations based on applicable environmental regulations and best management practices while regularly working with our customers to recycle scrap materials.
We also source materials from suppliers that align with our sustainability mission to reduce environmental impact through carbon-neutral programs, including our main source of pure nickel.
In 2023, we launched our Sustainable Supplier program. We are working with our suppliers to better understand their primary sources of emissions and ways that we can work together to reduce environmental impact.
