General Motors GM Opens First-Ever LEED-Gold Certified Automobile Manufacturing Facility Lansing, Mich. -- General Motors’ new Lansing Delta Township Assembly Plant has received a gold certification from the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) program. The building is the only automotive manufacturing plant in the world – as well as the largest facility and the most complex manufacturing site -- to ever receive any level of LEED certification. Over the first ten years of operations, the facility is expected to save over 40 million gallons of water and 30 million kwh of electricity. LEED Certification
