Construction carbon assessment: challenges and method
Construction is highly emission-intensive through materials (concrete, steel) and site energy. Environmental regulation (RE2020, EPDs) is structuring here.
Main emission sources
Construction materials (concrete, steel, insulation) dominate by far, ahead of site energy, machinery and transport. The footprint is mainly upstream (Scope 3).
Reduce and comply
Low-carbon materials (decarbonised concrete, wood, reuse), electric machinery and optimised logistics. EPDs and RE2020 require knowing products' footprint. UltraCarbon certifies the footprint of materials and components.
Frequently asked questions
What is an EPD (FDES)?
An Environmental and Health Declaration Sheet: the standardised LCA of a construction product, including its carbon footprint. It feeds RE2020.
Is concrete the main issue?
The cement in concrete is highly emitting. Low-carbon concrete, wood and reuse are major reduction levers.
