The intent of the study was to prove the concept and functionality of developing calculators for estimating embodied carbon at the scale of a city and assessing whether this type of data would be useful for developing and communicating embodied carbon policies. The prototype calculators proved effective for estimating order-of-magnitude embodied carbon impacts of the different policies and were able to generate meaningful outputs that, with additional future research and development, could help inform real-world policy decision-making. For instance, preliminary results from the prototype calculators indicated that requiring reductions in building embodied carbon intensity was the most impactful for making city-scale reductions, followed by incentivizing adaptive reuse. However, multiple significant data and functionality gaps were identified as being critical for future development before the calculators could be applied in a real-world policy setting.Technical Report
