Abstract: This paper describes a novel way to integrate sustainability metrics into a critical path method (CPM) based project schedule. To date, common industry practices of project controls do not include quantification and monitoring of environmental emissions associated with projects. This research team has addressed this gap by developing a method of estimating 100-year global warming potential (GWP) CO2-equivalent emissions associated with each activity of a CPM schedule. This methodology will transform a CPM schedule into a holistic tool, which can be used by project owners, contractors, construction managers, and other stakeholders to make meaningful decisions on the basis of duration, resources, cost and GWP emissions. This novel technique can be applied on virtually any type of project, including residential and commercial buildings, special purpose construction (such as data centers), power/utilities, infrastructure projects (highways/railways, bridges, aviation, transit facility buildings, etc.), signals and communication systems, and more, as exemplified through a few fictitious examples in this paper.Additionally, the paper describes (1) potential relationships between GWP, and resources and cost as well as (2) the impacts of delays and change orders on GWP emissions.
