The International Aerospace Environmental Group (IAEG), established in 2011, is an international organization that focuses on environmental issues and regulations within aerospace. Boeing is one of the founding members of this organization along with 11 other industry leaders.
With the ever-increasing number of regulations adopted globally, there was a large need to have an organization representing our industry while focusing on the myriad laws and regulations impacting health and the environment.
This group seeks to drive continual improvement in the processes used by the aerospace industry, thereby delivering consistently high-quality products and regulatory compliance with reduced environmental impacts.
Chemical regulations can originate from any number of countries that are implementing new policies. However, many of the regulations that impact the aerospace industry’s use of certain substances are initially brought forth by the European Chemicals Agency (ECHA) or the U.S. Environmental Protection Agency (EPA).
One of the European Union regulations administered by ECHA is REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals). Companies that manufacture or import certain substances into Europe are required to register with ECHA, and collect and report information on substances imported or used above one metric ton per year.
ECHA evaluates the information that is submitted by companies and assesses the risk to human health and the environment. A substance may be identified as a substance of very high concern (SVHC) if it is carcinogenic, mutagenic, toxic for reproduction, or persistent or bioaccumulative and toxic. Materials that are labeled as SVHC may become subject to authorization under the REACH regulation for continued use in Europe. When a substance is placed on the authorization list it is assigned two dates: a last application date to apply for authorization and a sunset date, which is the date when the substance can no longer be used within Europe without having been granted approval to continue use through an authorization application.
REACH regulations do not only affect Boeing. They also have an impact on the operations of Boeing’s suppliers, some approved processors and maintenance repair operations that service Boeing aircraft.
IAEG currently has about 50 member companies representing more than half of the aerospace industry with a combined annual turnover of more than $400 billion. There are several working groups that have a variety of focuses, ranging from monitoring and surveillance to reporting and replacement technologies. In particular, Working Group 2 (WG2) focuses on replacement technologies and has more than 40 participants representing more than 26 member companies.
In late 2015, the IAEG executive committee approved a change in the IAEG charter to allow collaborative work between member companies under a collaborative agreement. This was followed by a revision to the WG2 charter to define how these collaborative activities could proceed. The years of 2016 and 2017 were dedicated to developing the process flow for new replacement technology efforts and establishing the initial projects’ statements of work and collaboration agreements.
Five replacement technology projects were initiated in 2017 and are described in the sidebar.
As part of the REACH regulation it is necessary for all businesses in the aerospace industry that conduct business in Europe to find replacements for the regulated hazardous chemicals. Many of these materials pose a great challenge to finding an alternative that performs well enough to pass the performance requirements.
Collaborative efforts among these companies shows that there is an industrywide effort to find alternatives to hazardous materials and to be more environmentally conscientious. Additionally, the cost savings can be significant for the participating companies; the collaboration allows each of these companies to contribute a portion of the project financing rather than each individual company funding the entire effort independently.
Collaborative research among competitors can be difficult and requires a careful balance of strategic sharing of proprietary information to advance the technology and protection of proprietary information for competitive advantage. Individual companies are responsible to use their unilateral business discretion to decide if and how to utilize results of the collaborative research and efforts.
We hope these initial collaborative projects will be the beginning of a great resource for the aerospace industry to overcome technical challenges and find solutions together for hazardous chemical replacements.
