Ecolab Named to Carbon Disclosure Leadership Index for Third Consecutive Year

Oct 2, 2012 10:00 AM EDT

(3BL Media) St. Paul, MN – October 2, 2012 – For the third consecutive year, Ecolab Inc. has been named to the Carbon Disclosure Project (CDP) S&P 500 Carbon Disclosure Leadership Index (CDLI). The CDLI highlights companies that have demonstrated a commitment to strategy, governance, stakeholder communications and transparency in their reporting practices.

"At Ecolab, we strive to manage our operations responsibly while we deliver sustainable solutions to more than one million customer locations around the world,” said Douglas M. Baker, Jr., Ecolab chairman and chief executive officer. "We are honored to once again be recognized by the CDP for our responsible business initiatives and commitment to reduce greenhouse gas emissions.”

The methodology used to score companies was developed by the CDP with guidance from PricewaterhouseCoopers LLP. Companies were scored on the comprehensiveness of their disclosure practices as well as on aspects of their company’s performance in relation to climate change. The report is used by institutional investors and the broader market to assess how companies are managing climate change issues.

Ecolab has made continued progress in its sustainability goals through several company initiatives and also partnered with customer locations around the world to help reduce waste and water and energy consumption.

The CDP is an independent not-for-profit organization that works to reduce the risks posed by climate change by encouraging almost 6,000 of the world’s largest companies to report on their climate change strategies, greenhouse gas emissions and energy use. More information, including a full list of the companies on the 2012 CDLI, can be found at www.cdproject.net.
