the world to achieve Platinum-level certification and the Tahoe Environmental Research Center (TERC) at Lake Tahoe, one of only five laboratories in the world to achieve Platinum-level certification.

In February 2014, UC Davis and Diamond Developers formed a joint venture to create a sustainable city in Dubai, United Arab Emirates.
