“…CO 2 coefficients of NCC and STC‐ZERO are obtained from Table 2. In Table 6, the data for PC steel stranded wire, steel deformed bars, PC steel strand fixers (steel), temporary steel fixer for AFRP tendons, sheath (polyethylene), scaffolding materials, water proofing surface materials are taken from the database of National Institute for Land and Infrastructure Management, Japan (2019) 27 as estimated by Shinozaki et al 36 Carbon coefficient of asphalt pavement materials are obtained from the paper by Kanda et al 37 Furthermore, CO 2 coefficients of AFRP and GFRP 28 are selected as described in Section 4.1. It is to be noted that the carbon emission of precast segment concrete, cast in situ concrete and traffic barrier concrete for the 2G Non‐metallic Butterfly Web Bridge (Bessodani Bridge) is estimated based on the corresponding applied concrete mix proportions utilizing the carbon coefficients of the component materials obtained from the reference materials 17,18,19…”
