Introduction: Strengthening the early warning of greenhouse gas emissions from agriculture is an important way to achieve Goal 13 Sustainable Development Goals. Agricultural carbon are part gases, and accelerating development green low-carbon great significance for China high-quality economic goal “carbon neutrality in peak dioxide emissions”. Methods: By measuring total agricultural seven administrative regions 2000 2021, paper analyzes influencing factors by using STIRPAT environmental pressure model, on this basis, predicts trend under different scenarios extreme learning machine model optimized genetic algorithm. Results: The results showed that improved algorithm can overcome shortcoming easy fall into local optimal solution, thus obtaining higher prediction accuracy. At same time, a continuous fluctuation trend, due constraints level, industrial structure, human capital, spatial differentiation. It worth noting that, context development, all have potential “peak emissions” 2030, with only slight difference at peak. Discussion: research provide evidence government formulate flexible, accurate, reasonable appropriate reduction policies, which helpful strengthen exchanges cooperation regional rural fixation, actively steadily promote China's neutrality”.

The contributions of this research are making the theoretical analysis impact mechanism urbanisation on carbon emissions efficiency (CEE), and then empirically analysing effects CEE in Western China from 2010 to 2019 by applying super-efficiency epsilon-based measure model with undesirable outputs Tobit model. Major findings are: (1) mean 11 western provinces show a trend declining increasing over those 10 years, demonstrating U-shaped change characteristics. (2) Guangxi has most significant decrease, while Chongqing showed only small fluctuation; Guizhou characteristic that first it rises, descends, rises again; CEEs Inner Mongolia Yunnan have been production frontier surface 2015, presents declining, after 2015. other six present increasing. (3) Chongqing, Sichuan, Mongolia, high level CEE, followed Shaanxi, Xinjiang, Guangxi, Guizhou, an intermediate Gansu, Ningxia, Qinghai, lowest CEE. (4) relationship, meaning process influence was inhibition, stimulation. At present, shows negative impacts tipping point not yet arrived. should follow path high-quality quickly shift right side curve.

With China’s proposed carbon peak and neutrality goals, energy conservation emission reduction are becoming increasingly urgent for the ecological protection high-quality development of Yellow River Basin. Based on a systematic combing through saving (ESER) policies in Basin, this paper empirically analyzed impacts objectives collaboration measures ESER efficiency prefecture-level cities by comprehensively adopting super-slack-based measure (Super-SBM) model two-way fixed-effect model. The results study found that: (1) with continuous improvement policies, level Basin has been significantly improved; (2) dual-objective significant promotional effect lag effect, while impact multi-objective is not significant; (3) dual-measure multi-measure can effectively promote This indicates that, terms objective setting be too much, should pay attention to mutual coordination different policy strengthen collaboration.

The concept of high-quality development (HQD) is characterized by its emphasis on efficiency, equity, and environmental sustainability. In the context China’s new urbanization development, metropolitan area plays a crucial role in facilitating sustaining HQD. This study focuses Changchun Metropolitan Area (CCMA) as case to measure efficiency (HQDE) at county level using super-efficiency SBM model spatial autocorrelation model. Additionally, we examine spatio-temporal distribution characteristics HQDE terms economy, innovation, coordination, greenness, openness, sharing (EICGOS). main findings are follows: (1) CCMA ranges from 0.7 0.8 with an initial rapid increase followed gradual decline; however, there notable variations among different counties. (2) Regarding structure within area, highest observed half-hour living circle 2-h accessibility while lowest found 1-h commuting circle. Over time, declining trend core leading areas. (3) dimensions, demonstrates economic (EDE), whereas green (GDE) exhibits lower levels compared other dimensions. Furthermore, efficiencies across all dimensions show decline over time. (4) Spatially distributed patterns reveal significant agglomeration areas for region. High-high predominantly concentrated central region southern Liaoyuan low-low primarily exist northwest Songyuan specific counties Changchun. To attain HQD CCMA, it advisable bolster scale city, mitigate developmental disparities between cities, expedite transformations old industrial cities. These offer valuable point reference optimizing resource allocation devising strategies foster regional
