UL Environment Issues Highest Available Sustainability Certification for Laptops

NORTHBROOK, Ill. Feb. 14, 2011

UL Environment tested the ThinkPad T420 to IEEE 1680.1 criteria including reduction or elimination of environmentally sensitive materials in product and packaging, energy conservation, end-of-life management and corporate environmental practices. 

"The market for more environmentally-friendly laptops is growing due to consumer preference, energy regulations and corporate sustainability practices," said Wenc. "We applaud Lenovo for their dedication to creating greener options for this industry, and are proud to offer them a certification that proves the environmental attributes of the Thinkpad T420."

During the testing process, UL Environment assessed product documentation and records, physically examined product samples, independently tested the product for compliance to ENERGY STAR® 5.0 requirements and conducted onsite audits of manufacturing facilities.
