Early Phase Integrated Carbon Assessment (EPIC) is a whole-life carbon tool developed by EHDD. It is designed to support climate-positive decisions during early project phases, when data are scarce but emission reduction potential is high. EPIC is a model which combines regionally specific background data with forward-looking projections and peer-reviewed findings. This allows EPIC to overcome the lack of data and assess the relative impact on a project’s embodied carbon footprint, operational carbon footprint, and landscape carbon foot print. EPIC allows users to enter only a few project parameters to test the most effective carbon reduction strategies. EPIC can be accessed as a free web application, or through our API.
