A new scoping study from the Lower Carbon Concrete Group (LCCG) and ConcreteZero published in October 2024 highlights viable solutions to close the "carbon gap" in UK concrete production by the early to mid-2030s. Concrete production is responsible for around 8% of global CO2 emissions, making decarbonising the industry an urgent priority.
The study defines the "carbon gap" as the difference between projected emissions from concrete production and a Paris-aligned pathway to net zero that is outlined in the UK government’s Industrial Decarbonisation Strategy. Focusing on the embodied carbon of concrete, the study explores several measures to significantly reduce emissions.
The analysis identifies the concept of "Goldilocks pathways"—viable routes to achieving net zero emissions that balance current best practices with innovative technological advances.
While existing solutions such as efficient use of concrete and reducing clinker content can kickstart progress, the report underscores that urgent, concerted and coordinated action across the sector is essential to fully close the carbon gap

Key Findings
Immediate action is required to rapidly progress and scale all potential concrete decarbonization levers to effectively close the carbon gap.
The development of near zero carbon Portland cement, including reclaiming cement from demolition waste and implementing carbon capture and utilization (CCU) technologies, is essential for reducing emissions.
Developing clinker-free concretes presents a promising avenue for achieving net zero emissions in concrete production while addressing the limitations of traditional materials.
The study emphasizes that closing the carbon gap will demand a coordinated effort across the industry. The findings of this report are likely applicable to concrete markets beyond the UK.
Next Steps: The LCCG is preparing a second phase of research to further test and refine the proposed methods, with funding and participation now being gathered.
