The purpose of this paper is to evaluate the monetary GHG reduction benefits and health co-benefits for the industrial sector under the imposition of a carbon charge in Taiwan. The evaluation proceeds from 2023–2030 for different rates of carbon charge for the GHGs by a model of “Taiwan Economic Input Output Life Cycle Assessment and Environmental Value” constructed in this study. It is innovative in the literature to simulate the benefits of GHG reductions and health co-benefits of air pollutions for the industrial sector under the imposition of a carbon charge comprehensively. The results consistently show benefits whether the charge is imposed on the scope 1 and scope 2 GHG emissions or on the scope 1 emissions only. The health co-benefits are on average about 5 times those of GHG reductions benefits in 2023–2030. The average total benefits with the summation of GHG reduction benefits and health co-benefits are 821.9 million US dollars and 975.1 US million US dollars per year, respectively. However, both the GHG reduction benefits and health co-benefits are consistently increasing at a decreasing rate in 2023–2030. The increased multiple for the rate of the carbon charge is higher than the increased multiple of the total benefits and this result shows that the increase of the carbon charge becomes less effective.

“…The assessment of carbon dioxide emissions CDE and economic costs related to the construction operations of unstabilized and stabilized base layers is performed by employing the "HERMES CO 2 " spreadsheet (Barbieri et al, 2021c). This tool evaluates the carbon footprints generated during a road lifespan as also documented by other studies (Pranav et al, 2022;Prasara-A and Bridhikitti, 2022). In this research, the focus is on the construction of a flexible pavement base layer and consequently only the "BASE" worksheet of the "HERMES CO 2 " spreadsheet is used.…”

“…Studies show that corundum-blended ECC could be an alternative pavement and/or pavement overlay composite material [53,60]. Moreover, ECC pavement overlay has not only superior mechanical and durability properties but also many advantages for life cycle assessment [59,60]. Hungria et al [61] evaluated a novel jointless ECC ultrathin whitetopping overlay.…”

“…Results from life cycle analysis showed that ECC overlay has better performance than unbonded concrete overlay and hot mix asphalt due to reduced thickness, long service life, and/or less frequent repair requirement. Pranav et al [60] performed an economic input-output life cycle analysis of ECC pavement overlay by incorporating corundum. Compared to full-depth concrete and ECC pavement overlay, corundum-blended ECC overlay pavement was a more sustainable material for almost all the parameters (economic impacts, energy consumption, environmental inventory, etc.)…”

Concrete structures cannot efficiently perform their functions over time due to chemical and physical external effects. Thus, enhancing the relationship between repair and aged structures, and also improving the durability properties of concrete is crucial in terms of sustainability. However, high costs, negative environmental effects, and incompatibility problems occur in repair/retrofit applications. Furthermore, three-quarters of the failures in the repaired/retrofitted structures are caused by a lack of repair durability. The need for repair in pavement/bridge decks is also frequently encountered, and early-age performance problems with repair materials cause pavement/bridge decks to be unavailable for certain periods of time. Engineered Cementitious Composite (ECC) can be effectively used as repair/retrofit and pavement/bridge deck material. It also has a minimal need for repair/retrofit thanks to its high durability properties. This article presents state-of-the-art research regarding the application of ECC as a repair/retrofit and pavement/bridge deck material. Studies in the literature show that the repair/retrofit properties of ECC outperform conventional concrete and steel fiber-reinforced concrete. ECC can be a solution to high early strength and drying shrinkage problems frequently encountered in the use of repair materials. It could also be used for different repair applications such as cast, sprayed, and trenchless rehabilitation. Moreover, ECC might fulfill specific requirements for pavement, pavement overlay, tunnel pavement, airfield pavement, and bridge deck. These superior performances are attributed to ECC’s kink-crack trapping mechanism, uniquely large inelastic strain capacity, strain hardening, high tensile strain capacity, and multiple microcracking and ductile behaviors, especially bonding behavior and self-healing.
