Pratt & Whitney continues to take a leadership role in the development of environmentally responsible products, services and operations.
Pratt & Whitney introduced the Green Engine Program in the 1990’s to focus our Design for the Environment efforts, with the goal to minimize the use of Materials of Concern (MOC) in Pratt & Whitney engine designs. This effort resulted in our latest family of engines being in the forefront of Green Engine technology in the aerospace industry.
Materials of Concern
It is the policy of Pratt & Whitney to eliminate or reduce the use of MOC in the design, manufacture, assembly, disassembly, maintenance, repair, overhaul, operation and disposal of our products. The Pratt & Whitney MOC lists identify materials that are prohibited or restricted for use in Pratt & Whitney products. The lists provide substance classifications in accordance with specification PWA 328 and CPW 625 for use during the product design approval process. Material or process substance use declarations are also based on the MOC lists, as applicable.

To meet customer and regulatory compliance requirements, Pratt & Whitney depends on suppliers to submit and update Material Declarations on request, and to respond to material declaration requests for existing designs using the Material Declaration form above.
Pratt & Whitney’s declaration form is updated periodically to meet business needs, and additional forms may be developed for different types of suppliers. It is Pratt & Whitney’s intent to request the minimum level of information required to meet business needs.
Reach Regulatory Compliance
Safe Use Communication
Article 33 in the REACH regulation requires that safe use information be communicated for Substances of Very High Concern (SVHC) when an article contains an SVHC in a concentration above 0.1 percent weight by weight (w/w). International Aerospace Environmental Group (IAEG) has developed user information for determining SVHC weight calculations. To date, Pratt & Whitney has identified the following SVHCs at greater than 0.1 percent w/w in articles:
Supplier Assessments
To evaluate business continuity and compliance risk in our supply chain, Pratt & Whitney performs assessments of certain aspects of REACH at select suppliers. The assessment questionnaire is updated periodically to align with supply chain risk.
EU/UK REACH Authorisations
The REACH regulations require an Authorisation for continued use of Annex XIV Authorisation List substances in the European Economic Area and the UK after their assigned sunset dates. Because certain substances do not currently have suitable alternatives for use in all aerospace applications, Pratt & Whitney has worked with several industry consortia to obtain Authorisation to sustain supply chain business continuity. However, all members of our supply chain remain responsible for understanding and taking action on their obligations under REACH.
