Strong focus Protecting the planet AAR is gathering baseline data to assess company-wide environmental impacts. In recent years at our facilities, we have focused on using energy more efficiently and are working to convert to LED lighting. We also continue to identify and evaluate opportunities to create a cleaner, safer workplace, and to adopt sustainable practices to reduce our environmental impact. Recent actions include: Cadillac, Michigan Installed a chiller at one of its facilities that recirculates chilled water to cool presses as opposed to using city water from a well field that was released to the sewer, resulting in savings in water and sewer usage. Miami, Florida Airplanes are washed with recycled water. Wastewater from our aircraft wash is treated to reduce metals before discharge to the sanitary sewer. Garden City, New York Installed new plastic media blast cabinet with an advanced filter recovery system that allows 99% recycling of media and minimizes waste. Oklahoma City, Oklahoma Continued focus on reduction of classified waste. Dispose of waste oils and off-spec fuels from the aircraft with waste disposal services that recycle. Trois-Rivières, Quebec, Canada Recycles battery and fluorescent tubes via a governmental program and disposes of used and expired hazardous products (e.g., Alodine, alumiprep, paint, oil) through a recycling supplier. Windsor, Ontario, Canada Partnered with Safety Kleen to remove all waste chemicals safely. Rockford, Illinois Installed five ION generators in two HVAC units to provide ionized air to the main and support office area, and to airplanes when under maintenance. ELECTRICITY WATER WASTE AIR Governing with integrity We believe that our Doing It Right ® culture is based in a foundation of strong corporate governance and values that emphasize not only ethics and compliance, but integrity. We strive to establish, implement and maintain an effective governance structure that is agile and responsive to business needs and evolving best practices, and that sets high ethical standards. Our Code of Conduct promotes these standards and guides our business practices and procedures. We require all new hires to complete the Code of Conduct training, and training is also an annual requirement for all employees. Setting high standards By putting quality and safety at the forefront of everything we do, we not only comply with industry standards, but set even higher expectations. This level of commitment requires the dedication of our entire team. We provide training, share best practices and promote a culture in which collaboration is key to identifying, reporting and eliminating any hazard or incident. We are proud that AAR was recognized in 2021 as the first independent third-party MRO for implementing a safety management system in accordance with requirements set forth in the SMS Voluntary Program by the Federal Aviation Administration (FAA), the European Union Aviation Safety Agency (EASA), Transport Canada Civil Aviation (TCCA) and the International Air Transport Association (IATA). As a startup back in 1955, we were supplying parts to the aviation industry, efficiently moving inventory and setting in motion our participation in America’s great technology boom. Today, as we continue to expand, our strong values, purpose-driven model and a culture of integrity provide safe, efficient and sustainable solutions for the aviation industry.
