Ge You said that group buys contribute to a low carbon life and happiness at a news conference Tuesday in Beijing.

The Chinese movie star has a contract with Lashow.com and is currently promoting the group purchase website's "proposal for low carbon happiness".

Lashow.com CEO Wu Bo said they are devoting themselves to bringing about happiness at low expense.

Group buying activities consume less energy and resources, and generate less carbon dioxide emissions, the company said in its handout.

Consumers gathered online on locally and nationally based websites to organize group purchases and save on various items.

Lashou.com, the group purchase website, launched on Mar 10, 2010.
