BETHESDA, MD -- An updated ranking of the environmental and sustainable practices of the United States' 10 largest publicly traded homebuilders will be released at 1:30 p.m. EST on December 7, 2010 in a major new report from the investment firm Calvert, one of the nation's leaders in the field of sustainable and responsible investing.

In alphabetical order, the 10 homebuilders ranked in Calvert's "2010 green homebuilder" survey are: DR Horton, KB Home, Lennar, MDC Holdings, Meritage Homes, NVR, Pulte Homes, Ryland Group, Standard Pacific, and Toll Brothers.

Among other things, the impact of the recession is gauged in the Calvert report as a factor in showing how the top U.S. homebuilders have held, gained or lost ground in the rankings. The 2010 report updates Calvert's first "green homebuilder" survey, which was issued in 2008.

News event speakers will be:

* Stu Dalheim, director, Shareholder Advocacy, Calvert;

* Report co-author Rebecca Henson, analyst, Sustainability Research, Calvert; and

* Jeffrey T. Mezger, president, CEO and board director, KB Home.

As an investor, Calvert seeks to discern how major U.S. homebuilders compare on policies, programs, and performance relating to the environment and resource efficiency. Calvert's 2010 Green Homebuilders Survey examines the 10 largest publicly traded US homebuilders on the basis of five "green" indicators: land, building materials, energy, water and climate change.
