Carbon12 is a wooden building in Portland, Oregon's Eliot neighborhood, in the United States. The eight-story structure built with Oregon-made cross-laminated timber (CLT) became the tallest wood building in the United States upon its completion.^[1]

Carbon12 is an 85 ft. (26 m) mixed-use building situated on the corner of North Williams Avenue and 12 Northeast Fremont Street. It was designed, developed, and built by Ben Kaiser of PATH Architecture and Kaiser Group Inc., using CLT panels made by Structurlam.^[2] With a rooftop deck, the height is 95 ft. (29 m).^[3] Work on the Carbon12 started in July 2016, and it was completed in 2018. It is named after the atomic weight of carbon (12 AMU), as the carbon footprint was one of the primary motivators to choose timber^[4] and its street address (12 NE Fremont St.). The Carbon12 building is advertised to be one of the most efficient and environmentally friendly wooden buildings in the U.S.
