SAN DIEGO, Sept. 27, 2013 /PRNewswire/ -- For the third consecutive year, Sempra Energy (NYSE: SRE) has been named to the CDP's prestigious Standard & Poors 500 Climate Disclosure Leadership Index, a tool used by investors to assess companies' disclosure of management practices related to greenhouse-gas emissions. 

The annual listing ranks companies on the S&P 500 that maintain good internal data management concerning climate change risks.  Only three U.S. utility companies are ranked on the 2013 Climate Disclosure Leadership Index.

"We appreciate this recognition of our sustainability efforts by the CDP," said Randall L. Clark, vice president of corporate responsibility and corporate secretary for Sempra Energy. "Our low-carbon business model is focused on natural gas, energy efficiency and renewable power."

Earlier this month, Sempra Energy also was named to the Dow Jones Sustainability North America Index for the third consecutive year and, for the first time, to the Dow Jones Sustainability World Index. 

In 2013, more than 5,000 companies worldwide were asked to report on climate change through the CDP (formerly the Carbon Disclosure Project) and its signatories, which represent $87 trillion, or one-third of the world's invested capital. The 2013 CDP S&P climate change report presents the progress achieved by 334 companies in reducing emissions, responding to climate-related risk and opportunities and mobilizing influence to manage climate change.
