Skanska Conceives Solution for Calculating Embodied Carbon in Construction Materials

Skanska USA, alongside the Carbon Leadership Forum and partners in industry, today announced the creation of the Embodied Carbon in Construction Calculator EC3 tool, a ground-breaking solution for calculating and evaluating the carbon emissions embodied within a wide array of building materials. The EC3 tool, which was initially conceived by Skanska and developed with C Change Labs, was jointly seed-funded by Skanska and Microsoft—who determined that a collaborative, open-source solution was the optimal path toward maximizing the impact of this groundbreaking tool in reducing global carbon emissions.

Two trillion square feet of buildings will be built or undergo a significant renovation between 2015 and 2050 worldwide, according to the independent non-profit Architecture 2030. Over the average 30-year lifecycle of a new building completed in 2019, roughly half if its carbon will come from embodied carbon—or the emissions associated with building construction, including extracting, transporting and manufacturing materials. Considering that materials used for construction are estimated to consume 75 percent of all new materials annually by volume, the case for reducing the carbon emissions embodied in building materials is clear.

Embodied carbon reduction is an imperative for Skanska in meeting its long-term carbon goals. Skanska is a signatory to the Paris Climate Accord which has set aggressive global emissions reductions. However, traditional assessments of a building’s emissions and life-cycle costs focus primarily on energy efficiency—or the operational carbon of a structure. Until now, due to lack of data or data too complex to evaluate, few tools or benchmarks were available to facilitate awareness of the embodied carbon opportunity—which is to reduce the carbon footprint of a structure even before it is made operational.
