Urgency reduce CO₂ emissions is present in various areas including architecture. To do this, it is essential to adopt a cyclical rather than linear perspective when approaching construction processes. To effectively achieve the decarbonisation of architecture, it is crucial to promote innovative and sustainable solutions, such as those promoted by Holcim , which enable carbon reduction throughout the entire life cycle of buildings. Globally scalable building solutions can be achieved by optimizing resources, leveraging 3D printing technologies, utilizing recycled materials, and integrating nature into the urban environment.. In exploring different options for achieving CO₂-free architecture, we selected approaches that support energy efficiency, modernization, the use of new technologies, and contribute to a positive impact on nature and the surrounding environment.
