Amidst the global shift towards a low-carbon development trajectory, hickory industry in Lin’an District is progressively embracing green, low-carbon, and sustainable practices. This study, leveraging life cycle assessment (LCA) methodology, meticulously scrutinizes carbon footprint of by segmenting its into two distinct subsystems: plantation factory. Through comprehensive, year-long monitoring soil greenhouse gas (GHG) emissions plantations, our findings underscore that while total GHG from eco-complex management (ECM) surpassed those intensive (IM) 10.7% (p < 0.001), ECM significantly mitigated per kilogram produced, achieving reduction 1.0495 kgCO2eq. advantage primarily attributable to ECM’s diminished reliance on chemical fertilizers. Within factory subsystem, when processing 1 kg hickory, digital incurred 2.5923 kgCO2eq kg−1, whereas family workshops exhibited lower 1.9544 kg−1. Notably, packaging stages collectively accounted for over 90% subsystem’s emissions, with natural being primary contributor during processing. To estimate emission potential within industry, this research draws parallels strategies employed other industries outlines tailored propel development.

Vegetation to some extent can reflect the overall state of ecological environment, and increasing vegetation cover improve quality environment. The southwest karst region China is a typical ecologically fragile area an important barrier. Against backdrop intensified human activities, dynamics in have attracted widespread attention. Analyzing changes their responses activities for regional development. This study based on SPOT-VGT NDVI data from 1998 2020 employs trend analysis, “baseline” determination, multiple regression, residual principal component analysis investigate characteristics China. Additionally, it quantifies specific impacts various these changes. research findings indicate that (1) over past 23 years, interannual variability seasonal differences been significant, exhibiting trend. Spatially, this demonstrates decreasing south north northeast. (2) Over time, areas where has improved gradually expand, effectiveness restoration increases with time. (3) Overall, influence growth landscape (4) socioeconomic factors affecting primarily include economic development level, population labor migration, urbanization development, construction. These results provide scientific basis formulating reasonable environment protection strategies by humans.

This paper explores how optimizing vessel speeds can help reduce carbon emissions in the maritime industry. Focusing on liner shipping routes between China and Europe, it examines pricing mechanisms, including taxes trading under European Union Emissions Trading Scheme (EU ETS), impact operational costs reduction. With use of advanced optimization methods, such as Non-dominated Sorting Genetic Algorithm-II (NSGA-II) Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS), this research balance adjusting minimizing emissions. The findings show that companies China–Europe route financial strain carefully managing voyage times. study compares two scenarios tax policy rights terms results comparison based given parameters indicate a reduction 1124 tons with scenario, while scenario allows more voyages yearly (5.24 vs. 5.30). demonstrates one being economical, other is also environmentally efficient.

Economic development often results in significant greenhouse gas emissions, contributing to global climate change, which demands immediate attention. Despite implementing various low-carbon policies promote sustainable economic and environmental progress, current evaluations reveal limitations deficiencies. Therefore, this study utilizes a dataset detailing policy intensity at prefecture-level city China investigate the impacts of these on carbon emission reduction from 2007 2022 334 cities, employing fixed-effects model. Additionally, it assesses policies’ efficacy. The findings indicate negative correlation between China’s supported robustly by multiple tests. Specifically, one-unit increase correlates with 0.53-unit emissions. Furthermore, heterogeneity analysis shows that variations urban agglomerations, resource endowments, pollution levels, intensities influence effectiveness reducing This underscores achieves reductions through technological innovation, industrial transformation, welfare crowding out, transfer, varying across different contexts, intensities. Based analysis, we recommend several policies: formulating strategies tailored local conditions, enhancing regional policies, establishing cross-regional coordination mechanisms, so on. These recommendations not only offer valuable insights for but also serve as useful references green other developing countries.

Although Chinese government proposed emissions will peak by 2030, how do different development models affect in future? Here, we analyzed spatial temporal trends of over past two decades. Then constructed STIRPAT model based on ridge regression analysis. Finally, one national eight at sub-regional scales were generated because effects population, economy, energy consumption vary across regions periods. Meanwhile, established nine future various levels, forecast their from 2020 to 2060 sub-region models.
