Based on a single market mechanism, the contract energy management model presents a new mode of energy saving. Due to the external impacts of energy efficiency, the market cannot achieve the ideal allocation of resources. Publicly funded energy-saving incentives can help fix the flaws in the energy-saving service market, thus increasing the efficiency and performance of energy-saving service companies. While designed to encourage contract energy management projects, the government's incentive policies are not achieving the intended effect because of the unequal distribution of support and the restricted range of incentives. Employing a two-stage dynamic decision-making framework, this article scrutinizes the influence of diverse government subsidy strategies on the operational choices of energy service firms, yielding the following conclusions: (1) Subsidies contingent upon performance, coupled with payment stipulations, prove more effective than fixed subsidies without such conditions. For effective contract energy management, the government's incentive policies should be differentiated across numerous energy-conservation fields. Energy-saving service providers in the same field, demonstrating varying levels of success, deserve uniquely designed incentives from the government. With the government's implementation of a variable subsidy policy, linked to pre-established energy-saving targets, each falling within a suitable range, a rise in these targets leads to a corresponding decrease in incentive effect on energy-saving service companies with lesser existing energy-saving capabilities. A subsidy policy lacking incentive negatively impacts energy-saving service companies performing below the industry average.
ZnS nanoparticles, embedded in a carbon aerogel matrix, were loaded onto the surface of zeolite NaA, creating a composite designated as C@zeolite-ZnS. This design utilizes zeolite NaA to absorb Zn²⁺ ions released by ion exchange and addresses the agglomeration issue of ZnS by employing the carbon aerogel as an efficient dispersion agent. Employing FT-IR, XRD, SEM, BET, and XPS analyses, the morphology and structure of C@zeolite-ZnS were assessed. Regarding Hg(II) ion removal, C@zeolite-ZnS demonstrated exceptional selectivity and a high removal rate, achieving a maximum adsorption capacity of 79583 milligrams per gram. At 298 K, with a pH of 6, an adsorption time of 30 minutes, and a Hg(II) ion concentration of 25 mg/L, the adsorption and removal rates were measured to be 9990% and 12488 mg/g, respectively. Thermodynamic studies have established that the adsorption process is characterized by a spontaneous uptake of heat energy. Beyond the initial adsorption cycle, the adsorbent displayed noteworthy stability and exceptionally high adsorption capacity, showcasing removal rates that went beyond 99%, after a maximum of ten cycles. In summary, the C@zeolite-ZnS composite, possessing stability, reusability, and the capacity to meet industrial emission standards following Hg(II) ion adsorption, presents a very promising prospect for industrial implementation.
India's rapid urbanization and industrialization have resulted in a gap between electricity demand and supply, which consequently reflects in higher electricity bills for consumers. Nationally, the worst cases of energy poverty are prevalent among lower-income families. Corporate social responsibility, a cornerstone of sustainable strategies, is the most effective tool in confronting the current energy crisis. Through an exploration of mediating variables, such as renewable energy resource (RER) appraisal, sustainable energy supply (SES) viability, and sustainable energy development (SED), this study seeks to determine the contribution of corporate social responsibility (CSR) to energy poverty alleviation (EPA). Data from professionals, economic experts, and directors across the country in 2022 was analyzed using a hybrid research methodology, specifically partial least squares structural equation modeling (PLS-SEM). Through rigorous research, the study ascertained that corporate social responsibility is a direct contributor to alleviating energy poverty. Furthermore, the research indicates that RER, SES, and SED are key drivers in reducing energy poverty. This study's findings will encourage policymakers, stakeholders, and economists to concentrate on the role of corporate social responsibility in tackling India's energy crisis. Further investigation into the mediating influence of renewable energy resources (RERs) on the study's value-added contributions is warranted in future research. The results of this study underscore CSR's function as an impetus for alleviating energy poverty.
The nitrogen-rich organic polymer poly(chloride triazole), designated as PCTs, was synthesized using a single step. This material functions as a heterogeneous catalyst, free of metal and halogen elements, to promote the CO2 cycloaddition in the absence of any solvent. Under the influence of 110 degrees Celsius, 6 hours, and 0.5 MPa CO2 pressure, PCT catalysts, featuring a profusion of nitrogen sites and hydrogen bond donors, catalyzed the cycloaddition of CO2 and epichlorohydrin to achieve an exceptional 99.6% yield of chloropropene carbonate. The activation mechanism of epoxides and CO2 by hydrogen bond donors and nitrogen sites was further investigated and understood using density functional theory (DFT) calculations. Concludingly, this investigation showcased nitrogen-rich organic polymers' versatility in CO2 cycloaddition. This paper offers insightful guidelines for the development of CO2 cycloaddition catalysts.

Essential to a country's economic growth, the construction sector generates a substantial quantity of construction waste, creating a significant burden for the environment and for society. Although past investigations have probed the effect of policies on construction waste management practices, a simulation model designed for ease of use while incorporating the dynamic, universal, and practical elements is conspicuously absent. A hybrid dynamics model for construction waste management, incorporating agent-based modeling, system dynamics, perceived value, and experienced weighted attraction, is developed to address this gap. Using data from the Shenzhen, China construction waste sector, this study evaluates the effects of five key policies on contractor strategic choices and the broader industry's trajectory. Resource management of construction waste is successfully facilitated by industry rectification and combination policies, minimizing illegal dumping, pollution during treatment, and lowering the treatment costs. The outcomes of this research will prove instrumental in guiding researchers, policymakers, and practitioners in evaluating the impact of construction waste policies and developing improved waste management solutions.
The financial market serves as a framework for this study's interpretation of pollution reduction by enterprises. Data on Chinese industrial enterprises is used in this paper to scrutinize the effects of bank competition on the amount of pollution discharged by these companies. Bank competition's influence on pollutant reduction is demonstrably significant, encompassing both overall and technical effects. Through streamlined financing, improved implementation of internal pollution control, and optimized bank credit resource allocation, bank competition actively works to reduce pollutant emissions. Further examination reveals that the types of banks and the levels of their branches can both play a role in moderating the effects of pollution reduction efforts, and the observed impacts demonstrate a substantial divergence under diverse environmental regulatory intensities.
