The construction industry contributes significantly to CO₂ emissions, particularly through the use of conventional concrete, which involves cement production. At the European level, the European Commission estimates that approximately 7–8% of total greenhouse gas emissions come from cement production (EC, 2024). In this context, low-carbon concrete solutions are becoming essential for achieving the climate objectives set under the European Green Deal.

In Romania, although the technology is available, its application remains sporadic. According to data from the National Institute of Statistics and the Ministry of Development, only 3% of infrastructure projects supported through the NRRP included the use of ecological concrete solutions in 2024. The technical criteria imposed in tenders remain general, and the lack of clear regulation on low-emission construction materials limits the adoption of these innovations.

Adopting these solutions could reduce emissions generated on a construction site by up to 40%, according to calculations by EIT Climate-KIC. Moreover, applying alternative mixtures with slag, fly ash, or geopolymeric binders provides performance comparable to traditional concrete, with clear environmental benefits.

Accelerating the transition requires an adapted regulatory framework, financial incentives, and professional training for builders. Without firm interventions, the industry will remain anchored in outdated technical solutions, with negative impacts on urban sustainability.
