Environmental Sustainability (greeNG)

Northrop Grumman's Conservation Efforts 

As a global security company, we share our customers' priorities and support their strategic objectives. As world events repeatedly demonstrate, the linkage between social stability, strong governance, environmental protection, and economic health is increasing. Therefore, commitments and action to conserve environmental resources and mitigate risks associated with climate change are of paramount importance for this generation and beyond.


The company is committed to achieving the greeNG 2020 goals which include:

  • Reducing absolute greenhouse gas (GHG) emissions 30% from 2010 levels;

  • Reducing absolute potable water use 20% from 2014 levels; and

  • Achieving a 70% solid waste diversion rate (percentage of total solid waste that is diverted from landfill).


We are integrating environmental sustainability into our organizational culture, applying a multi-faceted strategy that supports our corporate values and is balanced to drive value creation and performance. To increase and maintain focus on performance, our executives are accountable for achievement of sustainability goals. Environmental Sustainability is one of the company's non-financial corporate performance metrics.

The link between environmental sustainability and executive compensation demonstrates the level of commitment from our Board of Directors and reinforces the role of leadership and engagement throughout Northrop Grumman.


2016 Highlights:


2015 Highlights:

  • We attended the White House Supplier Greenhouse Gas Roundtable, hosted by President Obama and the Council on Environmental Quality, launched in conjunction with the promulgation of Executive Order 13693 – Planning for Federal Sustainability in the Next Decade
    • Executive Order 13693 establishes a 2025 goal for the federal government to reduce its greenhouse gas emissions by 40% from 2008 levels, with the explicit charge to achieving emissions reductions in its supply chain
    • Northrop Grumman was one of a dozen major suppliers to the federal government to attend the Roundtable, having demonstrated alignment to the federal government's goal via the 2020 greeNG goals
  • We scored a perfect 100 on the CDP Climate Change disclosure, earning our fourth consecutive disclosure leadership distinction and place on CDP's distinguished Carbon Disclosure Leadership Index.
  • The first Northrop Grumman-owned on-site solar power systems were installed and activated in St. Augustine and Melbourne, Florida. The systems generate 0.56 MW of clean power for the two sites.
  • We advanced our efforts to identify water conservation opportunities at our sites in California, in response to the unprecedented drought conditions and the California Governor's Executive Order B-29-15. Specifically, we:
    • Completed water use assessments at our large California sites to evaluate operational conservation and source alternatives to reduce potable water use; and
    • Established the Enterprise Water Council, comprised of sector facilities, engineering and EHS professionals to recommend water conservation project priorities that balance cost, water use impact, and risk mitigation drivers.
  • We conducted comprehensive solid waste assessments at select U.S. sites to evaluate waste streams and opportunities for waste reduction and diversion. Common opportunities observed include tailored engagement plans, innovative solutions and right-sizing disposal services to reduce waste generation and improve solid waste diversion.

The Palmdale Aircraft Integration and Center of Excellence earned Silver-level Zero Waste Certification from the U.S. Zero Waste Business Council, successfully diverting more than 90% of its waste from landfill, incineration and the environment.

The site was one of several Northrop Grumman locations recognized by the California Department of Resources Recycling and Recovery as a Waste Reduction Awards Program (WRAP) winner for comprehensive waste reduction and recycling activities.
