The BETCRETE 3.0 work package focused on Sustainability indicators has demonstrated that it is possible to collect and analyze key sustainability data from the concrete industry, and that the industry is moving in the right direction toward reducing its climate impact. The main reduction in average GWP (Global Warming Potential) per cubic meter of concrete has so far mainly been achieved through the increased use of alternative binders, supported by updated standards and improved cement types. However, further progress is constrained by factors such as stricter technical requirements, availability of alternative materials, slow implementation of updated regulations, and inconsistent climate-related demands in procurement processes.

To achieve long-term national roadmap goals, there is a clear need to establish a national database of sustainability indicators for the concrete sector, extend data collection over time, and develop new indicators that reflect different construction segments and industry changes. Future developments in low-carbon binders must also be integrated into sustainability assessments. Additionally, data systems must be developed to enable efficient digital data transfer and be accessible for small and medium-sized enterprises.

BETCRETE 3.0 has laid a solid foundation for future work. However, realizing the full potential of climate-improved concrete will require coordinated efforts in policy, innovation, standardization, and data infrastructure.
