The study finds that: (1) Overall, tax incentives significantly reduce corporate carbon and pollution emission intensities while enhancing production efficiency. When disaggregating tax incentives by different types of taxes, it is found that reductions in value-added tax, income tax, and business tax significantly lower carbon and pollution emission intensities, while reductions in consumption tax significantly improve corporate production efficiency; (2) The results of the heterogeneity analysis indicate that tax incentives significantly reduce carbon and pollution emission intensities for small-to-medium-sized enterprises and firms in non-pollution-intensive industries.

Interoperability—alignment of disclosure requirements across jurisdictions—enhances the effectiveness of reported information. Climate disclosure redirects capital from carbon-intensive activities by improving transparency and accountability. Corporate transition plans, defined here as strategies aligned with science-based targets (e.g., SBTi) or taxonomy-based criteria with interim milestones, transparent assumptions, and scenario analysis, are critical for investment decisions and competitiveness. However, companies, particularly SMEs, face limited data availability, high compliance costs, and fragmented regulatory approaches. Political resistance and divergent materiality standards further complicate global alignment. By mapping disclosure regimes and identifying points of convergence and tension, this study highlights how climate reporting supports the low-carbon industrial transition.

Real-time monitoring of the electrolysis process, time-dependent characterization of cathodic deposits, and electrochemical analyses reveal a three-stage cathodic deposition mechanism in the MKN molten salt system: initial underpotential deposition of Mg²⁺ transitions to co-deposition of Mg²⁺ and Al³⁺, and ultimately to exclusive reduction of Al³⁺, which is driven by progressive Al³⁺ accumulation.

This study proposes an innovative approach to quantify the degree of enterprise full production cycle management and construct an interpretable machine learning model with dynamic optimization, thereby addressing this challenge. By incorporating 12 soil pollution influencing factors, we predicted the soil benzo[a]pyrene (BaP) content of coking enterprises in China from 2020 to 2040. Additionally, we employed SHAP and partial dependence plots techniques to conduct an in-depth analysis of the relationships between each influencing factor and soil BaP content. The random forest algorithm was identified as the optimal model for predicting soil BaP content in coking enterprises, yielding an R² value of 0.771 and an RMSE value of 2.1. Among various influencing factors, full production cycle emission standard quantification result exhibited the most significant impact with an importance score of 24.4 %. Compared with natural environmental factors (such as sunshine, rainfall, and temperature), the production activities of enterprises themselves (such as production time and output) have a more significant impact on the accumulation of soil pollutants. The highest soil BaP content among coking enterprises in China in 2020 was 231.1 mg/kg. Assuming that the unpredictable variables such as output and the number of environmental violations remain unchanged, by 2040, the average content of BaP in the soil of coking enterprises is expected to increase from 6.1 mg/kg to 7.38 mg/kg, and the over-standard rate is expected to increase by approximately 12.24 %.

However, sustainability assessments often overlook key indicators such as the carbon footprint (CF), nitrogen footprint (NF), and net ecosystem economic benefit (NEEB). This study, therefore, aims to comprehensively evaluate the long-term effectiveness of substituting green manure (GM) for chemical nitrogen fertilizer (CNF) in improving productivity, nitrogen use efficiency, and NEEB, while simultaneously reducing CF and NF in a double rice cropping system. The experimental treatments included: no CNF (N0), conventional CNF (N100), N100 plus GM (GN100), 80 %N100 plus GM (GN80), 60 %N100 plus GM (GN60), and N0 plus GM (GN0). Annually, substituting GM for 20 % of N100 (GN80) increased grain yield by 12.2 %–99.1 %, harvest index by 3.4 %–20.8 %, nitrogen recovery efficiency by 38.5 %–148.0 % and NEEB by 19.0 %–129.0 % compared with N0, N100, GN100, GN60, and GN0 treatments. The results also revealed a strong positive correlation between CF and NF under GN80 and GN60 but showed trade-off relationships under N100 and GN100, indicating that reduced CNF substitution by GM can simultaneously mitigate CF and NF. In this study, methane emissions were the primary contributors to CF, while reactive nitrogen losses were the main drivers of NF. Compared with GN100 and GN0, GN80 significantly reduced annual CF by 24.1 % and 28.2 %, respectively. It also substantially lowered annual NF and yield-scaled NF by 17.3 % and 37.5 % relative to N100, and by 27.7 % and 31.3 % relative to GN100. Furthermore, GN80 notably decreased annual yield-scaled CF by 22 % compared to N0 and by up to 50 % compared to GN0. Therefore, we recommend the GM substitution for 20 % of N100 to enhance environmental sustainability without sacrificing yield or NEEB.

However, despite high removal efficiencies, WWTPs systematically release MPs into the environment through effluents. Beyond their direct ecological impact, MPs can act as carriers of micropollutants and pathogens. This study quantifies and characterizes MPs, including polyethylene, polypropylene, polystyrene, polyvinyl chloride, polymethyl methacrylate, and bio-based polymers, in the influent and effluent of five municipal WWTPs employing different treatment technologies. The selected WWTPs include a conventional activated sludge (CAS) system, a moving bed biofilm reactor, two plants with tertiary filtration (pile cloth and stainless-steel filters), and a hybrid CAS/membrane bioreactor (MBR). The study aims to systematically assess MPs removal efficiencies by applying a standardized method for sampling, preparation, and analysis. In-situ sampling was conducted using a pumping and filtration system capable of capturing MPs as small as 2 μm. Samples were treated with Fenton oxidation and density separation to eliminate potential interferences before polymer identification via thermal desorption gas chromatography-mass spectrometry (TD-GC/MS). MPs concentrations varied across WWTPs but remained within a relatively stable range (215.0–761.5 μg/L), corresponding to daily MP loads of 1.2–8.8 kg entering the plants. Polyethylene was the most abundant polymer in wastewater. Removal efficiencies varied by treatment technology, with MBR and tertiary filtration achieving the highest removal rates (&gt;99 %), unexpectedly followed by the CAS WWTP, which exhibited an MPs removal efficiency of approximately 99 %. Per capita MPs loads ranged from 26.1 to 296.8 mg/day in influents and 0.2–8.3 mg/day in effluents, depending on plant capacity and daily load. Despite high removal rates, WWTPs continue to discharge significant MPs quantities, particularly given that major polymers such as polyethylene terephthalate and polyamides were excluded from this analysis. This highlights the need for continuous MPs monitoring and improved removal strategies. Additionally, this study did not investigate sludge samples. However, MPs removal in WWTPs is strongly associated with their accumulation in sewage sludge, raising concerns about their fate during sludge disposal and potential environmental impacts.

Combined in situ infrared characterization shows that heating and the presence of competing molecules disrupt the cross-linked structure of EVA. Through theoretical calculations, it can be determined that the molecular polarity index and solubility parameters of BDG are closer to those of EVA, and it is found that there are mainly van der Waals forces and hydrogen bonding between BDG and EVA molecules, with stronger binding energy. Furthermore, the simulated diffusion behavior of the two solvents during EVA dissolution demonstrated that the diffusion of NMP and BDG exhibited sub-diffusive characteristics.

To address these issues, the present study proposes an innovative low-frequency vibration-assisted riveting (LVR) technology with low energy consumption, improving the rivet deformability and thus enhancing the joint strength and fatigue life.

Detailed Electron Backscatter Diffraction (EBSD) analysis unveils that LVR significantly promotes plastic deformation of the rivet and refines the grains, resulting in an improvement of the rivet hardness by 6.50% when compared to TR process. Notably, due to the vibration softening and friction reduction effects, this novel technique promotes material flow and increases rivet/hole interference by 43.87%, enhancing the shear strength and fatigue life of the joint by 6.69% and 47.75%, respectively.
