Main barriers
Cities transitioning to low-carbon infrastructure face challenges balancing growth with environmental protection. Expanding urban areas while retrofitting existing infrastructure requires investment and coordination. A key barrier is the misconception that new construction is better than circular practices like reuse and modular buildings, often seen as lower quality. Standardized regulations based on functionality, along with changing public and policy attitudes, are essential for wider adoption.
Assessing biobased materials requires extensive Life-Cycle-Analysis (LCA), accounting for sourcing, use, disposal, and reuse. New EU LCA requirements in 2025 will impact how companies evaluate carbon footprints for buildings over 1000 sqm.
Green and blue infrastructure faces obstacles from competing land uses and sustainability concerns. Long-term maintenance and community engagement are crucial but difficult to prioritize. Uncertainty around carbon capture and negative emissions technologies adds complexity, and electrification efforts require addressing grid capacity, stability, and equity. These challenges emphasize the need for cohesive strategies, investment, and supportive policies for long-term sustainability.
