“…However, from the back end, it appears that the situation is worse in terms of a carbon‐free atmosphere. Natural climatic changes can generate a variety of problems, such as sustaining the effects of global warming and causing the decline of natural settings such as agriculture, marine life, and land vegetation (Mohammed et al, 2021). Artificial processes can also lead to higher carbon dioxide emissions.…”

Policymakers face a daunting task when it comes to achieving sustainable environmental development and avoiding additional environmental degradation. This study examines the significance of green technology innovation and green financing in creating a more sustainable environment. The impact of green technology innovation and green investment on carbon dioxide (CO2) emissions has yet to be empirically and theoretically examined in the literature, especially in conjunction with a moderating component, particularly social globalisation. Accordingly, this research examines the role of green technological innovation and green financing in reducing CO2 emissions in the G7 countries. Our study uses empirical research data from a panel of the G7 countries covering the period 1995 to 2019. We employ advanced panel approaches to address panel data analysis concerns, such as cross‐sectional dependence, structural break, and slope heterogeneity (the Banerjee and Carrion‐i‐Silvestre unit root and cointegration test and cross‐sectional augmented ARDL). This study shows that green technology innovation (GINV) as well as green financing (GFIN) have a negative but significant impact on CO2 emissions. Whilst economic growth has shown a positive and significant impact on CO2 emissions in the G7 countries, social globalisation positively moderates the relationship between CO2 emissions and GDP, but negatively and significantly causes GFIN and GINV with CO2 emissions amongst the G7 countries. According to our study, countries would be able to meet the United Nations' SDG‐7 and SDG‐13 targets if they implemented green financing and green technology policies.

“…The meaning of Ca-CO 2 -H 2 O system is the reaction between calcium and CO 2 in the presence of water under natural or accelerated conditions from humidity, temperature, pressure, and duration to form calcium carbonate (CaCO 3 ). The products from this system are called precipitated calcium carbonate (Mohammed et al 2021).…”

Mineral carbonation based on lime (Ca(OH)2) and carbon dioxide (CO2) is a carbon sequestration and also a soil improvement method. This paper investigates the effects of varying Ca(OH)2 (1%, 5%, and 10%) and water ratios (6%, 7%, 8%, 9%, and 10%), and mineral carbonation duration (1 hr, 3 hrs, 5 hrs, and 7 hrs) on the conversion of lime to calcium carbonate in clay-free sand. Two different silicon sand samples which have different grain sizes were used in the experiments. Reacted lime ratio, used lime ratio, and unused Ca2+ ratio were calculated. The lime fixation point was determined as 1% by the total weight of the soil. The average carbonation ratio at the lime fixation point was found to be 84.10 ± 7.75%, which was the highest value. As the lime in the soil increased, the reacted lime and the use of lime decreased. The appropriate water ratio was determined as 6%. Fines supported the conversion of more lime to calcium carbonate. The conversion of lime to calcite was completed in the first few minutes (short-term), but the strength of the lime-treated soil improved over time. The progress of the mineral carbonation reaction in the solid was according to the Dome Principle (DPinC). The conversion of lime to CaCO3 ratio, reacted lime ratio, used lime ratio, and unused Ca2+ ratio was calculated for the first time.

“…CO 2 capture and storage and mineral carbonation methods play an important role in reducing the amount of CO 2 in the atmosphere. Mineral carbonation uses industrial, natural, and waste minerals that have calcium or magnesium in their composition so that they can capture CO 2 through the carbonation process [29].…”

“…According to Mohammed, et al [29], mineral carbonation improves soil strength because the new carbonation products expand and ll voids in the soil, which increases strength. Carbonation in stabilized soils is limited by pressure and CO 2 concentration.…”

Although the treatment of soils with lime-based materials is used in many earthworks projects, there are only a few studies that deal with the quantification of their carbonation.The objective of this work was to investigate the influence of carbonation in mixtures between two samples of tropical soils and Electric Arc Furnace Slag (EAFS) in terms of Unconfined Compressive Strength (UCS), mini-CBR index, mini-CBR expansion, and Resilient Modulus (RM) properties. Four types of curing were used: (1) conventional sealed curing in a humid chamber; (2) conventional sealed curing in a humid chamber followed by unsealed curing with exposure to air; (3) conventional sealed curing in a humid chamber followed by unsealed curing in an accelerated carbonation chamber. In addition, tests were performed to determine the carbonation depth by spraying phenolphthalein, pH, scanning electron microscopy (SEM), and X-ray diffraction (XRD). It was found that the results of the soil-EAFS were better than those of the soil samples not stabilized for all the curing processes analyzed. In the curing processes (1), the formation of calcium aluminum silicate hydrate structures (CASH) was found to improve the mechanical behavior of soil-EAFS mixtures. The formation of calcium carbonate (CaCO3) was observed in curing processes (2) and (3), which significantly improved the mechanical properties. Thus, the carbonation process increases the strength and stiffness of the soil-EAFS mixtures, which guarantees the durability of these mixtures over the years.
