The Early Phase Integrated Carbon Assessment (EPIC), created by EHDD, serves as a comprehensive tool for evaluating carbon emissions throughout the entire lifecycle of a project. Intended to aid in making climate-positive choices during the initial stages of development—when information may be limited yet the potential for emission cuts is significant—EPIC integrates region-specific background information with future projections and scholarly research. This innovative approach enables EPIC to compensate for data shortages and evaluate the overall influence on a project's embodied, operational, and landscape carbon footprints. By allowing users to input only a few basic project details, EPIC facilitates the exploration of the most effective strategies for reducing carbon emissions. Moreover, EPIC is readily available as a free web application, as well as through an API for broader accessibility and integration. This accessibility makes it easier for project teams to incorporate sustainability into their planning from the outset.
