Can Northrop Grumman Hit Net Zero by Backing Small Suppliers
Northrop Grumman’s latest sustainability report outlines its ESG initiatives, with a strong emphasis on emissions reductions, employee engagement and ethical supply chains.
The company targets net zero greenhouse gas emissions across its operations by 2035, aiming for a 50% reduction by 2030.
“Motivated by our mission and the countless lives around the world counting on us, this team stands ready and committed to deliver a brighter, more sustainable future for all,” says Kathy Warden, CEO at Northrop Grumman, in the report.
Reducing emissions across the supply chain
Supply chains play a crucial role in Northrop Grumman’s sustainability goals.
The company reported a 13% drop in emissions compared to its 2019 baseline and sourced 12% of its electricity from renewable sources in 2024. To meet its net zero target, it is working with suppliers to reduce emissions throughout the production and logistics chain.
Beyond emissions, Northrop Grumman is tackling water and waste management. By 2030, the company plans to cut overall water withdrawals by 10%, reuse 10% and replenish another 10%, prioritising areas where water scarcity is a concern.
At the same time, it aims to reduce solid waste sent to landfill and incineration by 10%. These efforts require strong collaboration with suppliers to ensure responsible sourcing, waste reduction and more efficient manufacturing processes.
Strengthening ethical and diverse supplier networks
Ethical and responsible supply chain management remains a key focus. The company works closely with suppliers to uphold high standards of integrity, transparency and compliance.
In 2024, more than 99% of Northrop Grumman’s full- and part-time employees completed ethics training, reinforcing a culture of accountability across the organisation.
Northrop Grumman also continues its long-standing commitment to supporting small businesses.
It exceeded the US government’s 23% small business spending target for the 20th consecutive year, with 35% of its total domestic spend going to small suppliers. This investment in smaller firms strengthens local economies, drives innovation and ensures a diverse range of suppliers contribute to its defence and aerospace projects.
The company’s focus on supply chain sustainability extends to technology and innovation. Through its Technology for Conservation (T4C) initiatives, Northrop Grumman expanded supplier engagement, with a 14% rise in participants across 75 sites.
New projects such as Virtual Reality SAFE and the Project Reclaim Recycling Process were launched to improve resource efficiency and reduce environmental impact.
Embedding sustainability in operations
Sustainability is not just about emissions and supply chains; it is also embedded in Northrop Grumman’s workplace culture and corporate citizenship efforts.
Employee engagement is a priority, with 86% of workers reporting a positive experience at the company. A further 82% feel a strong sense of belonging and inclusion.
Safety remains central to operations, with Northrop Grumman maintaining incident rates below the aerospace industry average. “Our commitment to safety and environmental protection remains central to our business,” says Mike Witt, Vice President of Corporate Environment, Health and Safety and Chief Sustainability Officer.
Community engagement also plays a role in the company’s sustainability strategy. Employees contributed nearly 140,000 volunteer hours in 2024, valued at US$4.6m.
Additionally, more than 2,000 employees donated $1.7m through the ECHO Workplace Giving Program, reinforcing Northrop Grumman’s role as a responsible corporate citizen.
As Northrop Grumman continues to innovate in aerospace and defence, sustainability remains a guiding principle.
With strong commitments to emissions reductions, responsible supply chains and ethical business practices, the company aligns its long-term success with global sustainability goals.
