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.



CO₂ Emissions Intensity


Looking ahead, we will continue to drive toward our intensity goal by:

  1. Recycling waste heat from our furnaces to improve efficiency of furnace operations.
  2. Converting natural gas-fueled boilers and furnaces to electric.
  3. Increasing the share of carbon-free grid electricity, using renewable and nuclear based energy.
  4. Improving our operational efficiencies.



Our product portfolio and specialty alloy manufacturing operations are differentiated from the many traditional metal manufacturers around the world, resulting in lower GHG emissions intensity compared to those metal manufacturers:

  • Our specialty alloys do not require the coking or iron ore operations that are found in carbon steels, which require carbon-intensive inputs like coal.
  • Our melting operations use low-carbon electric arc furnaces and vacuum-induction melting furnaces, as opposed to blast furnaces.
  • The majority of our material inputs are from reclaimed or recycled steel and alloys.
  • Over 90% of our electricity is sourced from nuclear power and other carbon neutral sources of power.

Our reported environmental data covers all manufacturing operations. The data is tracked at the facility level and reported to the EHS team using a data management system and defined process.




Crude Steel CO₂ Emissions Intensity

Although Carpenter Technology manufactures specialty alloys and stainless steels, we are often compared to the broader steel industry. To help put our emissions into the context of the broader steel industry and align to SBTi's steel industry sector decarbonization approach, we also report our crude steel emissions intensity. As demonstrated, our crude steel emissions intensity is world-class for the industry and below SBTi's publicly stated target for a "well below 2dc" scenario.





We also aspire to achieve net-zero carbon emissions by 2050 for Scope 1 & 2 emissions. Meeting this goal will require technological advancements, such as carbon capture systems and the use of hydrogen in specialty alloys, and customer partnerships before becoming commercially feasible. We are committed to evaluating and investing in new technologies that will move us towards a net-zero future.


To set these targets, we conducted a detailed assessment of our operations, including onsite audits and an analysis of our historical data. We identified a set of opportunities to reduce CO₂ emissions, then prioritized those initiatives based on the greatest impact.

We also reviewed the Science Based Targets initiative (SBTi) guidance for the steel industry. SBTi’s sector decarbonization approach for the steel industry is based on the production of crude steel. Using the SBTi approach — measuring our emissions intensity only for manufacturing crude steel — we are below the target levels for a “well below 2°C” scenario. However, we continue to process material beyond the initial melting step associated with crude steel; our targets are for the entirety of our operations.
