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.
Carpenter Technology’s Board of Directors maintains overall responsibility for Environmental, Social and Governance (ESG) related matters, including climate- related risks and opportunities. The Science, Technology, and Sustainability Committee reviews the actions and progress of sustainability efforts to reduce environmental impact, including reporting of metrics.
Carpenter Technology's ESG Steering Committee, which includes functional and business leaders, ensures the Company’s sustainability strategy is aligned across the enterprise and defines annual and midterm targets that inform our public reporting.
The Environmental, Health and Safety (EHS) team at Carpenter Technology oversees our environmental management system with technical experts in all facilities where we operate. The EHS team develops policies and protocols that establish our global standards for energy management and greenhouse gas emissions, air emissions, waste, water, scrap metal recycling, sustainable sourcing, safety standards, and training. In addition, the EHS team is responsible for ensuring we are compliant with applicable legal and regulatory requirements while aligning with best practices.
In 2023, Carpenter Technology received ISO14001 Certification for our facilities in Clearwater, FL; Hartsville, SC; Orwigsburg, PA, and Washington, PA. This brings the total number of ISO14001 certified facilities to nine, covering the largest facilities that generate over 90% of our business.
We identified a set of transition risks associated with the shift to a low-carbon and climate-resilient economy, including: carbon pricing relevant to facilities and products, mandates and regulations on existing products and services, and shifts in consumer preferences. We also recognize that extreme weather events pose a physical risk to our supply chain that could impact our operations.
We also see opportunities in the transition to a low-carbon economy: additional growth through new sustainable products and markets, and improved operational performance through increased efficiency of our operations. We believe we are well-positioned to take advantage of the opportunities as detailed in the Sustainable Solutions section.
We continuously track progress and seek opportunities for more goal setting activities to further minimize our impact.

In 2022, our Scope 1 and 2 emissions remained nearly flat over 2021 levels, despite the increase in production. As a result, our emissions intensity dropped to 3.14, more than 20% lower than our 2021 level. This came as a result of increased efficiencies in our plants, including higher manufacturing productivity and reduced heat waste. We also replaced certain equipment that ran on natural gas with an electrical alternative.
Metal manufacturing is an energy-intensive process, primarily using electricity and natural gas to melt and process metal alloys. Carpenter Technology actively monitors and manages energy consumption across all operating locations. Our goal is to maximize energy efficiency to reduce costs and minimize our impact on the environment. This is primarily achieved by minimizing manufacturing waste and material reprocessing.
We aim to achieve this by investing in new, more efficient technologies for furnace operations, lighting, and HVAC systems. In 2022, our energy intensity was 77.0 GJ per metric ton, a large improvement over 2021 intensity (95.1 GJ per metric ton) due to increased productivity in our plants and energy-saving programs like the LED replacement program at our Reading, PA facility.
Our Reading, PA facility has replaced hundreds of traditional HID light systems with LED fixtures. In some instances, energy usage has been reduced to 1/3 of original energy consumption and has improved safety through increased lighting levels while also minimizing the maintenance burden typically required with traditional lighting systems.
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. One recent example of water consumption and discharge reduction was the implementation of a water recirculation system, allowing our Reading facility to reuse and recycle more than 90% of water used in production. Looking ahead, we plan to introduce and expand the following activities to our other facilities:
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.
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 2022:
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.
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.
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.
