The greeNG Program

Our focus on environmental performance extends beyond compliance. Our corporate values strongly support environmental sustainability and it is an important subject to our many diverse stakeholders. Our greeNG Program is leading the charge in integrating environmental sustainability throughout our organization. Through a focus on resource conservation and efficiency in our operations, we are driving long-term affordability that is providing value to our customers as well as our shareholders.

Environmental sustainability is one of six nonfinancial performance metrics at Northrop Grumman, stressing its importance throughout the organization. The Policy Committee of our Board of Directors oversees the alignment of the program with Northrop Grumman's strategic objectives.

Employee participation is a key driver of our success. In 2017, we launched a new internal program website and voluntary training module to further engage and educate employees on their role in advancing environmental sustainability at Northrop Grumman. Our annual Earth Day celebrations provide opportunities for employees to learn more about how they can get involved with environmentally-focused initiatives at work, home and within their communities.

METHODOLOGY

Our environmental sustainability goals, along with greenhouse gas, water, and solid waste inventories, include our full portfolio of facilities where we have operational control (consolidation approach). This represents more than 98 percent of our global floor space.

 

We develop our inventories in accordance with The GHG Protocol Corporate Standard and in alignment with the International Aerospace Environmental Group Greenhouse Gas Reporting Guidance.

 

We are committed to maintaining high-quality data and performance tracking through third-party verification to the International Organization for Standardization (ISO) 14064-3. We perform verification of our Scope 1 (direct), Scope 2 (indirect, location- and market-based), and Scope 3 (other indirect) Business Travel emissions and Water use data.

Greenhouse Gas Emissions Reduction
Greenhouse Gas
Emissions

To reduce greenhouse gas emissions from our operations, we focus on improving the efficiencies of our buildings, information technology infrastructure and manufacturing processes.

2017 Highlights

  • Exceeded and remain committed to our 2020 reduction goal of 30 percent.
  • Implemented projects that are estimated to reduce annual emissions by 10,180 MTCO2e.
  • Two new buildings received LEED certification
  • Northrop Grumman received an A- for leadership performance on the CDP Climate Change program.

Our CDP Climate Change response is available on our website and includes details on our climate change risk management, energy consumption and Scope 2 market-based and Scope 3 emissions.

Potable Water Use Reduction
Water
Conservation

We are committed to minimizing our water consumption and emphasizing action in regions where water stress is a reality, including California and parts of Australia. Our conservation efforts are enhancing our environmental stewardship and creating long-term operational cost savings for the company.

2017 Highlights

  • Implemented water conservation projects to reduce annual water consumption by 64 million gallons per year.
  • Reduced water use at our California locations by 11.8 percent from our 2014 base year.
  • Completed two additional site water assessments. In total, the 11 completed site assessments represent more than 70 percent of our water use.

Solid Waste Diversion
Solid Waste
Diversion

To minimize our impact on local landfills, we focus on solid waste management by creating opportunities to optimize our processes, minimize material use and reduce costs. Our strategies for increasing solid waste diversion include recycling, composting, reuse, and donating useful supplies to local organizations.

2017 Highlights

  • Implemented solid waste projects estimated to divert approximately 400 tons from landfill.
  • Performed 25 site solid waste assessments to better inform our solid waste management strategies.
  • Our El Segundo and Redondo Beach, California facilities implemented paper towel composting to divert 50 tons of material per year from landfills.
  • Our Linthicum, Maryland facilities expanded recycling programs and installed recycling compactors, diverting 33 tons of waste from the landfill.

Diversion Rate2

Diversion Rate

1) GHG emissions are in units of Metric Tonnes Carbon Dioxide Equivalent (MTCO2e) and include gases CO2, CH4, N2O, HFCs, PFCs, SF6, and NF3.
2) Diversion rate includes waste to energy but does not include construction and demolition debris.

Renewable Energy

We continue to evaluate opportunities to procure renewable energy for our facilities. In 2017, the following renewable energy sources produced 22,111 MWh of electricity:

  • Two Northrop Grumman owned on-site solar systems.
  • One landlord-owned solar system installed at a leased facility.
  • Long-term purchase commitments for Renewable Energy Certificate (RECs).

Green Buildings

In 2017, we received LEED certification for two new buildings at our Melbourne, Florida and Linthicum, Maryland sites. We have operations in 15 certified green buildings, which total more than two million square feet of floor space.

13 Buildings

U.S. Green Building Council Leadership in Energy and Environmental Design (LEED) standards.

2 Buildings

U.S. Environmental Protection Agency ENERGY STAR® Program for energy-efficient equipment and building systems design.

ECOSYSTEM
CONSERVATION

Forests play an important role in sequestering carbon and maintaining biodiversity around the world. To promote forest conservation, we continue our multiyear commitment and purchase of 11,000 MTCO2e of American Carbon Registry-certified carbon offsets.

These conservation-based carbon offsets are generated by the Mississippi Valley Reforestation Project in the southeastern United States and support the reforestation of one million acres of the Lower Mississippi Alluvial Valley, one of the most important ecosystems in North America.

ZERO Waste

In Palmdale, California, our Aircraft Integration Center of Excellence maintains its Silver level Zero Waste certification from the U.S. Zero Waste Business Council. This signifies more than 90 percent of site waste is diverted from landfill, incineration and the environment.

First aerospace production and manufacturing facility in the United States to receive this certification.

RAINWATER HARVESTING

The rain harvesting system at Northrop Grumman subsidiary Park Air Systems in Peterborough, United Kingdom captures rainwater from the roof, filters the water and stores it in the tanks shown. The water is used for toilets on the ground floor of the building and saves more than 120,000 gallons per year, a reduction of 70 percent of water use at the facility.
