“…They found that the LCT effect of high-carbon state-owned firms is not obvious. Based on scenario analysis, Wang et al [ 57 ] compared the LCT potential of three tobacco companies through process optimization and product structure upgrades, and finally provided recommendations. By empirical research, Li [ 58 ] discovered that 30 per cent of power firms in China have high LCT efficiency.…”

To achieve the goals of carbon peak and carbon neutrality, the low-carbon transformation (LCT) of high-carbon firms is inevitable. We construct game models of a supply chain with different dominant types under a mixed carbon policy that embraces carbon cap-and-trade and carbon tax. Solving each dominant model, we derive the effective area and optimal threshold of the mixed carbon policy to guide LCT. We find that the selling price, market demand, and profit of the supply chain system are equal in different dominant models due to the mixed carbon policy, but when a company dominates the supply chain, its profit is higher than when it is a subordinate. In addition, the high-carbon manufacturers (HCM) will pursue LCT only when the sum of the carbon tax rates and carbon trading prices is within a certain threshold, and the subordinate HCM are more likely to be driven to pursue LCT. Therefore, the government should adopt a differentiated hybrid carbon policy, setting a high (low) carbon tax rate for the HCM in a dominant (subordinate) position.

“…Li et al (2017) analyzed the carbon footprint of the manufacturing section of a domestic brand of cigarette based on the LCA method. Wang et al (2018) developed a comprehensive energy consumption model to provide a theoretical basis for reducing emissions in the cigarette yarn-making section. No carbon footprint studies have been reported for tobacco growing, which is an important stage of tobacco production.…”

Introduction: Tobacco, as a significant cash crop in China, warrants a comprehensive investigation into the spatiotemporal dynamics of its carbon footprint in order to address greenhouse gas (GHG) emissions and foster low-carbon, environmentally friendly agricultural practices.Methods: Employing the life cycle assessment (LCA) methodology, this study aims to scrutinize the temporal variations in the carbon footprint across different functional units of tobacco production in China from 2004 to 2017, thereby elucidating its composition and key influencing factors.Results and Discussion: The findings reveal that the average carbon footprint per unit area and per unit yield of tobacco production in China during the aforementioned period amounted to 4,098.99 kg CO2-eq∙ha−1 and 1.97 kg CO2-eq∙kg−1, respectively, exhibiting an upward trend over time. Notably, fertilizer and agricultural films emerged as the primary sources of greenhouse gas emissions in Chinese tobacco production, accounting for 26.63% and 24.54% of the total emissions, respectively. Remarkably divergent carbon footprints were observed among various provinces in China. Specifically, Jiangxi, Hunan, and Guangdong exhibited the highest carbon footprints per unit area, with values of 4,908.65 kg CO2-eq∙ha−1, 4,852.90 kg CO2-eq∙ha−1 and 4,833.56 kg CO2-eq∙ha−1, respectively. Likewise, Jiangxi, Fujian, and Yunnan recorded the highest carbon footprints per unit yield, reaching 2.31 kg CO2-eq∙kg−1, 2.23 kg CO2-eq∙kg−1 and 2.22 kg CO2-eq∙kg-1, respectively. Conversely, Inner Mongolia, Hebei, Jilin, and Heilongjiang exhibited lower carbon footprints per unit area, namely, 3,952.06 kg CO2-eq∙ha−1, 3,751.08 kg CO2-eq∙ha−1, 2,935.81 kg CO2-eq∙ha−1, 3,264.83 kg CO2-eq∙ha−1 and 2,830.92 kg CO2-eq∙ha−1, respectively. Moreover, these regions displayed both high yield and productivity. This investigation highlights the significance of implementing measures such as scientific fertilization, reducing agricultural film usage, and expediting the mechanization process of tobacco cultivation to foster the development of an environmentally sustainable tobacco industry in China.

“…Two scenarios were created to replace the initial embodied carbon by modifying two variables within the system framework. The results demonstrated that increasing prefabrication rates and adopting low‐carbon materials would significantly reduce carbon emissions (Wang et al., 2021).…”

The aim of this article is to identify and estimate different inventories of emissions during construction activities. A unique approach for simulating construction materials and their stochastic embodied greenhouse gas (GHG) emissions is proposed. The % of carbon released by various equipment and materials with respect to construction activities was also measured to assess emissions inventory supported by construction project case example. Finding shows that the gross carbon emissions from construction materials was 5419.576 ton of CO2 whereas carbon emissions from sustainable construction materials was 752.383 ton of CO2. The findings of the study, which revealed a significant potential for an 86.19% reduction in carbon emissions by utilizing substitute substances in construction materials compared to conventional materials, have led to the proposal of important measures. These measures are crucial for identifying the primary sources of carbon emissions in construction activity and play a pivotal role in promoting sustainable construction practices and achieving green ratings for construction projects. The research will help sustainable construction & will pave the way for achieving an effective green rating for construction projects.
