Reducing embodied carbon in floor build-ups

About this CPD

The floor zone is one of the largest sources of embodied carbon on a residential project. This CPD breaks down where that carbon comes from — cement content, screed thickness, insulation choice — and shows the specification changes that move the needle.

Backed by independently verified Environmental Product Declarations, we look at how anhydrite screeds can reduce embodied carbon by up to 90% compared to traditional cementitious systems.

Learning outcomes

• Read and compare EPDs for floor screed products.
• Understand the carbon impact of cement content and screed thickness.
• Identify lower-carbon alternatives without compromising performance.
• Align floor specification with RIBA 2030 and LETI targets.
