Chris has been designing and building zero-carbon buildings throughout his 25-year career. From 2005 to 2018, he was a lead instructor in a hands-on design/build program at Endeavour Centre and was responsible for many zero-carbon, zero-toxin, and zero-waste buildings.
In 2019, he helped found Builders for Climate Action and codeveloped the BEAM tool for measuring material emissions in residential buildings. He authored four major studies of embodied carbon in new construction for Canadian governments and helped Canadian cities develop an embodied carbon policy.
Chris published eight books on green construction, most recently coauthoring Build Beyond Zero: New Ideas for Carbon Smart Architecture (Island Press, 2022) with Bruce King. He also manages the Carbon-Free Buildings Program at the Rocky Mountain Institute.
