Addressing the embodied carbon data gap

Aecom also reviewed carbon tools and noted further inconsistency. The report authors warn: “The variation between carbon tools and their outputs limits the ability for carbon assessment results to be compared. This, in turn, restricts the development of consistent datasets, impacting the development of clear, consistent benchmarks and targets. Furthermore, this may encourage gamification and hinder competition within the carbon tool market, as industry will likely wish to utilise the tool that produces the lowest carbon assessment results.”
