2017 Corporate Forum Participation

In 2017, we participated in EHS forums across the United States. As corporate members, we received valuable updates and information with regards to health, safety and environmental sustainability.

As a founding member of the International Aerospace Environmental Group (IAEG), a global aerospace and defense industry association, we support environmental compliance and environmental sustainability initiatives in collaboration with our peers to discuss and find solutions common to industry challenges. Engaging with IAEG provides Northrop Grumman with a forum to discuss our challenges and provides valuable insights into the concerns of our industry peers that might affect our business in the future. We engage both at the Board level, supporting the organization’s governance and strategy, as well as at the work-group level, providing subject matter expertise for the following work groups:

  • Chemical Reporting.
  • Replacement Technologies.
  • Greenhouse Gas Management and Reporting.
  • Reach Process Authorization.

  • Supply Chain Environmental Sustainability Survey Harmonization.
  • ISO 14001: 2015 Transition Guidance.
  • Toxic Substances Control Act Compliance.


Through robust environmental compliance programs and awareness campaigns, we remain committed to conducting our operations in a manner that minimally impacts surrounding environments.

  • Comply with all applicable laws and procedures within our regions of operation, adhere to Northrop Grumman policies and procedures and reduce our environmental footprint.
  • Strive for excellence and promote efficiency, affordability, innovation and forward-thinking in our operations.

Hazardous Waste Management

Northrop Grumman is committed to responsibly managing hazardous waste generated within our operations in compliance with any legal requirements. Our corporate policies emphasize maintaining visibility on our hazardous waste (HW) streams from the point of generation to final disposition and minimizing HW where it is economically and technically feasible. HW generation is a standard byproduct of our business operations, and fluctuates based on product demand and development as well as operation and maintenance of our sites. As a result, our EHS professionals spend time ensuring HW is managed and disposed of properly. The data below represents HW generated from product manufacturing, research and development and facilities and maintenance activities at our U.S.-based, auditable sites.

Chemical Management

As a Department of Defense contractor, emerging technologies, material specifications from our customers, and fluctuations in demand for our product drive our use of hazardous materials. We comply with the federal Toxic Release Inventory (TRI) Program reporting requirements by calculating total usage of chemicals covered under this program. In addition to tracking usage, our employees also look for opportunities to substitute and minimize the use of toxic chemicals where possible. We are committed to responsibly managing chemical usage in Northrop Grumman operations in compliance with any legal requirements.

The TRI data represents all U.S.-based operations required to report to the EPA and/or state governments, and follows the EPA’s reporting schedule.


Our commitment to ensuring strong environmental, health and safety performance is demonstrated by the presence of our Corporate EHS audit program. Our internal audit department has delegated responsibility for managing and administering global EHS compliance audits to Corporate EHS. Delegating this responsibility helps ensure that company professionals who understand EHS compliance and management are reviewing performance. The scope of the audits includes federal/national, state and local regulatory requirements, standards organization codes (e.g., fire codes) and company policy and procedures. Our audits also assess each site's EHS Management system, which is required by company policy and is evaluated based on ISO 14001 and OHSAS 18001 standards.

Our practice is to conduct Corporate EHS compliance audits at auditable sites every three to four years. Assessments of our management systems emphasize the effectiveness and integration of key fundamentals into day-to-day business operations.


EHS management determines auditable sites by reviewing operations at our facilities using tools such as questionnaires, site visits and telephone interviews to evaluate the existence and extent of EHS-related risk. If the EHS risks warrant review, then those facilities are included as auditable sites. We conduct reviews of site operations and auditability annually or as operations change at Northrop Grumman sites. Northrop Grumman’s audit program is global and, at present, includes sites throughout North America, Europe and Australia. Currently, there are 77 Northrop Grumman sites in the audit program, which accounts for 72 percent of the company's global square footage.


Each Corporate EHS Audit is led by an EHS management systems auditor who evaluates each site's compliance management strategies and the overall effectiveness of the site's compliance program. The audit team composition is an important consideration during the annual audit scheduling process. Audit teams are formed to ensure sufficient subject matter expertise is available; audit topics are appropriately assigned; and to make sure the audit team is given adequate time to conduct a thorough review of the EHS programs at the site. These subject matter experts are assigned a topic within the audit to review and evaluate.


We are continuing to strengthen and increase transparency of our audit program through the use of an Environmental Management Information System (EMIS). Our audit program, sectors and sites will begin utilizing this system in 2018. The system will automate our audit process by creating efficiencies in execution, review of findings, and timely closure of corrective actions. In addition, this system will provide management at all levels of the organization an opportunity to conduct more comprehensive trend analysis. Focusing on trend analysis will improve our ability to benchmark EHS program performance throughout the company and focus on continual improvement. For more information on our Health and Safety programs see page 43.


In addition to establishing an internal EHS management system, we have 23 ISO 14001 registered sites across the globe, which make up approximately 38 percent of Northrop Grumman square footage and include approximately 28 percent of our employees. These sites work diligently to achieve and maintain this widely recognized certification.

In 2017, the Northrop Grumman Australia Office received both the AS/NZS ISO 14001:2015 and AS/NZS 4801:2001 certifications, highlighting the team’s commitment to EHS excellence.
