A Carbon Tool (ACT) is an open source web application that enables users to estimate embodied carbon equivalent (LCA) content from Building Information Models (BIM) - using Speckle to solve the challenge of data interoperability in the AEC industry. It is designed to provide quick and efficient feedback during the design process to enable users to identify carbon hotspots and reduce the impact their design has on the built environment.
