Invited Speaker: Measuring embodied carbon in foundations: Why, how, and whatâ€™s next?-PPT Presentation

PPT Presentation

Pdf Summary

The presentation explains why and how the geotechnical industry can measure and reduce embodied carbon in foundations, while advancing sustainability and climate action. Drivers include climate commitments, regulations, client requirements, supply-chain expectations, and the potential to reduce costs and project risks.<br /><br />The EFFC–DFI Carbon Reduction Guide recommends action across materials, procurement, transportation, worksites, and electricity. Key strategies include reducing material quantities, choosing lower-carbon or reused materials, engaging suppliers, setting procurement standards, and using Environmental Product Declarations (EPDs) for product-specific carbon data. The industry’s free Excel-based carbon calculator measures cradle-to-gate emissions across Scopes 1, 2, and 3, using project inputs such as materials, fuel, electricity, transport, equipment, and waste.<br /><br />Case studies show practical results. At a Singapore refinery expansion, stone columns and vibro compaction replaced driven concrete piles, cutting estimated emissions by 75% while also offering schedule and cost advantages. In a Florida high-rise project, redesigning drilled shafts reduced concrete use and carbon by 10%, alongside cost and schedule savings. Further reductions may come from lower-carbon cement, reused steel, improved site investigation, carbon-focused design, and load testing.<br /><br />The presentation also highlights the circular economy: eliminate waste and pollution, keep products and materials in use at their highest value, and help regenerate nature. Geotechnical firms can take quick steps such as reusing site spoils, drilling fluids, and materials, and reducing waste through better design. Foundation reuse is a larger opportunity, supported by testing, analysis, and reliable records of installation.<br /><br />The central message is that carbon reduction is achievable on every project and can bring financial and schedule benefits. Progress requires better data, earlier design decisions, material availability, and a shift toward planning foundations for reuse and value beyond their initial service life.
