UPS (NYSE: UPS) has been named to the 2011 Carbon Disclosure Project's Global 500 "Carbon Disclosure Leadership Index" and is one of only four companies in the world to receive the highest score.

UPS scored 99 out of 100 on the Leadership Index, demonstrating UPS's strong commitment and continued high performance on environmental issues.

"I am sincerely gratified UPS's commitment to sustainability and transparency is being recognized by one of the world's most respected organizations evaluating environmental performance," said Scott Wicker, UPS's chief sustainability officer. "Our programs to improve our energy efficiency, to reduce our carbon impact and to invest in new alternative fuel technologies are paying off in creating a better environment for our employees, our customers and our communities."

The index, a key component of CDP's annual Global 500 report, highlights the constituent companies within the FTSE Global Equity Index Series (Global 500) that have displayed the most professional approach to corporate governance regarding climate change information disclosure practices. Companies are scored on their climate change disclosure, and high scores indicate good internal data management and understanding of climate change related issues affecting the company.

The index is compiled by Pricewaterhouse Coopers (PwC) on behalf of CDP and provides an evaluation tool for institutional investors and other stakeholders. In 2011 it includes 52 companies from the Global 500 Index based on analysis of responses to a CDP questionnaire, which focused on greenhouse gas emissions, emissions reduction targets and risks and opportunities associated with climate change.

"Companies that make the Carbon Disclosure Leadership Index have demonstrated good internal data management practices for understanding greenhouse gas emissions," said Paul Simpson, chief executive officer of the Carbon Disclosure Project. "They have shown a strong awareness of the business issues related to climate change including climate-related risks and opportunities. Those organizations that give clear consideration to measuring and reporting on climate change issues will be best placed to capitalize on the opportunities from managing them."

The DJSI reports on the sustainability performance of companies based on an in-depth analysis of economic, environmental and social criteria such as corporate governance, water-related risks and shareholder relations, with a special focus on industry-specific risks and opportunities.
