A CARBON FOOTPRINT ASSESSMENT FOR MANUFACTURING AND CONSTRUCTION PROCESSES OF BUILDING SLOPE EROSION CONTROL

Abstract

The increasing emission of greenhouse gases has raised the global surface temperature, contributing to natural disasters. The construction industry is the third-largest emitter of greenhouse gases, following electricity generation and transportation. To mitigate its impact, sustainability concepts have been integrated into construction practices, including the use of alternative materials, improved construction efficiency, and carbon footprint assessments. However, existing carbon footprint assessment methods remain limited, particularly in infrastructure projects. This study applies a carbon footprint assessment framework to evaluate key emission factors in the production and construction of embankment erosion protection using reinforced concrete lining. The results indicate a carbon footprint of 27.37 kg CO₂ per square meter, with concrete and reinforcement steel contributing 82.5% and 9.7%, respectively. The main sources of emissions include material use, fuel combustion in transportation, and energy consumption in material production and construction processes.
