Adaptive Approaches to Attain Net Zero Through Carbon Sequestration in Heritage Sites of Coastal Mediterranean Cities
摘要
Cities are facing colossal challenges, where the globe is turning to a boiling era, superseding global warming. Mediterranean nations bear witness to a dramatic surge in carbon emissions, culminating in a staggering 46 °C temperature record in July 2023, a rate 20% faster than the global average. This surge precipitates alarming consequences: rising sea levels, severe floods, wildfires, and sandstorms, all attributable to climate change (CC). Inaction threatens dire consequences for these nations, necessitating urgent measures to mitigate carbon emissions and adapt to CC. Carbon sequestration (CSn) emerges as a pivotal strategy in combating carbon emissions and CC. Drawing inspiration from natural processes found in forests, soil, and water bodies, CSn entails capturing and storing CO2, thereby reducing overall emissions. Implementing CSn techniques within the built environment offers the promise of widespread emission reversal. Urban areas can host carbon sinks (CSks) strategically placed to capture CO2, particularly in vulnerable coastal regions, aligning preservation efforts with sustainable architectural practices. Abandoned coastal heritage sites emerge as prime candidates for this transformative role, capable of sequestering carbon from both air and water. This study explores adaptive strategies for converting coastal heritage sites (CHSs) into CSks, facilitating CO2 sequestration towards achieving Net Zero (NZ) emissions while honouring historical legacies. The study examines CHSs across urban landscapes poised for integration into carbon sequestration initiatives. As a case study, the “Cita Della Scienza” building in Bagnoli, Naples, Italy, situated in one of the largest industrial zones along the coastal stretch east of Naples, embodies this potential. Predominantly built with steel and bricks, this structure presents an opportunity for preservation by transformation into a carbon sink hotspot. Retrofitting strategies include diverse CSn approaches, such as integrating greenery and bio-based materials native to Italy, ensuring environmental and cultural relevance.
