Bridges Carbon Calculator
This easy-to-use spreadsheet tool created by Atkins for the BCSA and Tata Steel calculates the carbon footprint of typical steel composite bridges. It requires a minimum of data and preliminary design quantities to generate an initial result, which can be further refined as more information becomes available. It is accompanied by a helpful User Guide explaining exactly what the tool is, and how to use it. The results are displayed graphically showing the relative proportions due to construction, maintenance, and traffic delays. The construction element is further sub-divided to show the proportions for the deck, substructures and foundations. This allows a bridge designer to see where the major CO2 burdens are, allowing the focus of design development to be on the big issues in terms of reducing emissions.
