Caterpillar Inc. last week announced it has been named to the Dow Jones Sustainability Indexes for the ninth straight year and has retained its Sustainable Asset Management Gold Class position in the Industrial Engineering sector. Columbus, Ind.-based Cummins Inc. was named to the Dow Jones Sustainability World index for the fifth year in a row.

Launched in 1999, the annual DJSI process involves a thorough analysis of corporate economic, environmental and social performance, assessing issues such as corporate governance and citizenship, risk management, climate strategy, standards for suppliers, product stewardship and occupational health and safety.

“As Caterpillar continues on its sustainability journey, our ongoing inclusion on the DJSI exemplifies our progress in aligning our sustainability efforts with our business strategy,” said Doug Oberhelman, Caterpillar group president.

A key focus for Caterpillar over the past year has been progress toward 2020 goals for products, services and solutions, as well as operations. Caterpillar continues to look for opportunities to improve efficiencies in operations and products and services offerings, increase recycling and remanufacturing, as well as increasing life cycle value throughout its product line.

“Our employees, dealers and suppliers continue to work together to help our customers achieve improvements in material and energy efficiency, emissions reductions and job site safety,” said Oberhelman. “At the same time, energy efficiency continues to be a key focus in our facilities; and we continually challenge ourselves to find innovative ways that will increase efficiency while reducing emissions.”

Caterpillar’s annual Sustainability Report further highlights the company’s focus on sustainability. The 2008 Sustainability Report, titled “Big Picture,” highlights how a focus on sustainable development continues to present a significant opportunity for business growth and profitability for both Caterpillar and its customers.

In the past year, Cummins expanded its Supplier Code of Conduct, has made solid progress toward achieving its greenhouse gas reduction commitment, developed a set of principles to guide its climate change strategy, updated its business case for diversity, and re-energized its corporate responsibility efforts.

“Cummins is committed to creating a thriving and sustainable business that values its stakeholders, the communities in which it operates and the environment,” said Tim Solso, Cummins chairman and CEO. “While we strive every day to be a better company, it is gratifying to see that our efforts are being recognized once again by inclusion in the well respected Dow Jones World Sustainability Index.”
