On October 16, 2013, Ms. Sara Greenstein, Senior Vice President of UL and President of UL's Environment Business Division, and a four-member UL delegation paid a business visit to China Building Materials Test and Certification Group Co., Ltd. (hereinafter referred to as "CTC"). CTC General Manager Ma Zhenzhu, Deputy General Managers Shi Xinyong and Chen Lu, Board Secretary Huang Lihua, and others accompanied the meeting.

The two sides introduced their respective development and business situations, and conducted extensive exchanges and discussions on EPD certification for green building material products, LCA product life cycle assessment, and other topics. The two sides reached a preliminary consensus on further strengthening cooperation between CTC and UL in business areas such as hazardous substance testing, environment, and safety. Founded in 1894, UL is a globally leading product testing and certification organization and the founder of U.S. product safety standards. As an institution with leading comprehensive strength in the field of domestic building materials and construction engineering inspection and certification, CTC's cooperation with UL will help promote China-U.S. technical exchanges in areas such as building materials product standards, testing methods, certification specifications, and environmental health, and further play a role in promoting China-U.S. trade and supporting the upgrading and transformation of China's traditional building materials industry.

The UL delegation also visited the exhibition room of China Building Materials Academy, the State Key Laboratory of Green Building Materials, and the CTC Environmental Testing Laboratory.
