MADISON, WI - January 14, 2008 - Leonardo Academy announced today the release of the post-event emissions offsets report for the CB Richard Ellis Group, Inc. September 2007 World Conference and further announced that this event has earned Gold Level Certification for offsetting event emissions under Leonardo Academy's Cleaner and Greener(R) Certification Program. To earn this level of certification, the CB Richard Ellis conference offset more than 200% percent of its carbon dioxide emissions that affect climate and more than 60% of each of the emissions covered by the program that affect health. The final report, containing graphics that show the sources of the emissions, the emissions and the offsets, can be downloaded from: http://www.leonardoacademy.org/Resources/reports/index.htm.

The Leonardo Academy's Cleaner and Greener(R) Program certifies organizations and events for offsetting emissions from energy use. This program addresses the emissions that impact both human health and climate. Leonardo Academy worked with CB Richard Ellis to calculate the emissions caused by this event and gathered donations to support offsetting these emissions. Michael Arny, President of Leonardo Academy, said, "Reducing and offsetting emissions that affect climate and health is a critical part of reducing our environmental impacts. Everyone can take action and follow the leadership of CB Richard Ellis and the donors that supported these emissions offsets."
