Thinking differently about embodied carbon (again)
The construction sector is once again confronted with a challenge it thought it had already mastered: understanding and managing embodied carbon in a way that is accurate, consistent and genuinely useful. Although the term has become familiar across the industry, its practical application remains clouded by misconceptions. The RKD article argues that the industry must “think differently” about embodied carbon, especially as upcoming European regulations will require mandatory disclosure for large buildings from 2028 and for all buildings from 2030. This shift places embodied carbon at the centre of design decision‑making rather than treating it as an optional add‑on.
Embodied carbon encompasses all emissions associated with a building before it is occupied and after it reaches the end of its life: material extraction, manufacturing, transport, construction, maintenance and demolition. While the calculation may appear straightforward on paper, the reality is far more complex. Every choice involves assumptions about materials, industrial processes, datasets, methodologies and system boundaries. The apparent simplicity of the formula hides a network of variables that demand technical expertise and consistent criteria.
The article highlights several common pitfalls: assuming that a simple calculation means a simple problem; overlooking the fact that mitigation benefits unfold over decades; and underestimating the true complexity of materials and their supply chains. To move forward, the industry must professionalise its approach, improve data quality and adopt coherent methodologies that allow results to be compared reliably.
The core message is unambiguous: embodied carbon is no longer an emerging concept but a critical design parameter that will determine the sector’s ability to meet European climate targets. Thinking differently means embracing its complexity and acting with greater precision, transparency and responsibility.
