  7. Abstract:
  8. The destruction of structures due to disasters such as earthquakes and floods can cause significant environmental damage. Debris from collapsed structures is typically collected and transported through processes that involve the consumption of fossil fuels, and it is then dumped in landfills. Rebuilding the destroyed structures also requires materials and fuel, leading to further environmental harm. Therefore, the removal and transportation of debris, as well as the reconstruction of damaged structures, impose additional environmental damage through the consumption of non-renewable resources and the emission of various pollutants. Most research on sustainable construction has focused on the embodied energy of building materials and energy consumption during the construction and operational phases. Studies indicate that fewer analyses have been conducted on the damage caused by poor-quality construction and structures lacking resilience to natural disasters, as well as their environmental impacts. The objective of this study is to calculate the carbon footprint resulting from the demolition of non-resistant buildings against disasters per square meter and to estimate the environmental damage caused by the lack of structural resilience. The findings of this research can be used in developing regulations and policies aimed at reducing environmental pollution by promoting resilient construction and the retrofitting of vulnerable structures. In this study, common construction practices in Iran are first identified, and the resources consumed per square meter of building, including materials and fuel, are quantified. Subsequently, various sources of pollution emissions throughout the construction to reconstruction cycle are identified, and their mechanisms and quantities are determined. The amount of pollution generated per square meter of building is then calculated and presented based on the amount of carbon emissions. Quantitative assessment of the carbon footprint of the modeled building is essential for advancing research and providing strategies to reduce building carbon emissions. Finally, measures such as determining the level of damage and imposing fines, and their impact on reducing the negative effects of non-resilient construction on the environment, will be examined
