As Northrop Grumman continues to grow as a global security company, we remain committed to sustainable performance through effective environmental stewardship; strong corporate citizenship; devotion to diversity and inclusion; and maintenance of high standards of ethics, business conduct and corporate governance.
Our purpose at Northrop Grumman is to provide our customers with products and services that help them meet their critical mission requirements. As Northrop Grumman continues to grow as a global security company, we remain committed to sustainable performance through effective environmental stewardship; strong corporate citizenship; devotion to diversity and inclusion; and maintenance of high standards of ethics, business conduct and corporate governance. They are fundamental to our business success, part of our key measurements and integral to our culture.
An important demonstration of our commitment to sustainable top performance is our Corporate Responsibility Report, which we have published since 2008. The third-party-reviewed report is consistent with Global Reporting Initiative standards and helps us to track our corporate responsibility progress.
Among our sustainability achievements in 2016: We were honored as an industry leader in the Dow Jones Sustainability Index for North America, and we maintained our leadership on the Carbon Disclosure Project (CDP) Climate Change disclosure ranking. We extended our commitment to ethical business conduct into our supply chain through an updated Supplier Code of Conduct, reaching approximately 9,500 supplier companies. And we were ranked 31st on DiversityInc’s annual list for the Top 50 Companies for Diversity. We were the only aerospace and defense company to make the list.
Northrop Grumman’s commitment to environmental sustainability is demonstrated by our 2020 greenhouse gas reduction, water conservation and solid waste diversion goals. They complement our environmental conservation support within our communities and, for our customers, where our innovative technologies are meeting their needs for operational effectiveness as well as environmental analysis. For example, our radar and sensor capabilities provide global climate and weather information to decisionmakers, enabling them to understand the risks of changing environmental conditions on their missions.
Two important tenets of our corporate citizenship are to expand the global pipeline of diverse and talented science, technology, engineering and mathematics (STEM) students and to assist our veterans. In 2016, Northrop Grumman and the Northrop Grumman Foundation contributed more than $19 million to diverse STEM-related groups. Additionally, for the past 10 years, our Operation IMPACT (Injured Military Pursuing Assisted Career Transition) program has focused on assisting severely wounded service members as they transition from the military to the private sector.
I’m proud of our performance in environmental sustainability, and I particularly want to recognize our employees whose efforts are keeping us on our path to corporate responsibility leadership.
