Cummins Recognized as Sustainability Leader on Global, Regional Levels

COLUMBUS, Ind. (Sept. 13, 2007) -- The Dow Jones Sustainability Index has named Cummins Inc. (NYSE:CMI) to its World index for the third year in row, recognizing the Company' s continued commitment to economic, environmental and social leadership. This index represents the top 10 percent of the world's largest 2,500 companies in these corporate sustainability metrics.

In addition to the World Index, Cummins was also named to the North American index, which represents the top 20 percent in each sector.

The updated indices, based on Dow Jones' annual review, become effective with the opening of the equity markets on Sept. 24.

Cummins is one of the 11 U.S. companies among the 45 global members of the industrial goods and services sector on the World Index. In its annual review, the Dow Jones Sustainability Index analyzes companies in three broad categories -- economic, social, and environment counting for 22, 36 and 42 percent, respectively, of the total score in the industrial sector.

Specific issues considered include corporate governance, risk management, branding, climate change, supply chain standards, labor practices, corporate citizenship and philanthropy, employee development, environmental management systems, and environmental policy and procedures and the scope of their application.

“We are honored to be included among this elite group of companies that have demonstrated a commitment to sustainability issues,” said Christine Vujovich, vice president, marketing and environmental policy. “Cummins strives to deliver value and excellence to all its stakeholders, whether they are investors, customers, employees, or the communities in which we live and work. We aim for continued improvement in these important sustainability areas, but this recognition is a sign that our efforts are headed in the right direction.”

Cummins works hard to make improvements to its sustainable practices every year. For example, Cummins has committed to reducing its global greenhouse gas emissions by 25 percent as a percentage of net sales from 2005 to 2010, as part of its membership in the U.S. Environmental Protection Agency' s (EPA) Climate Leaders Program. To meet this goal, Cummins has engaged the internal expertise of its environmental and facilities leaders to make energy assessments and improvements in its operations.
