Carbon emission inequality has become a critical factor constraining the coordinated development of socio-economic systems and natural environment. This exacerbates disparity in carbon emissions across regions, hindering efforts to achieve sustainable environmental justice. Previous research primarily focused on structure footprints their influencing factors, but there been limited quantitative inequality, particularly from multi-scale perspective. study constructs 250 m-high-resolution consumption-based footprint grid for China uses Theil index reveal significant spatial inequalities footprints. The results indicate that smaller-scale analyses better spatiotemporal heterogeneity within regions. At county level, exhibit inequalities, with hotspots concentrated regions such as Beijing–Tianjin–Hebei, Yangtze River Delta, Pearl Delta. top 5% areas highest (139 cities) contributed 19.6% national total, indicating concentration few large cities. decomposition shows county-level cities 55% inequality. also reveals complex relationship between income, well urban-rural disparities. underdeveloped central western pronounced lag effect, growth rate rural surpassing urban areas. impoverished inter-provincial marginal overlap significantly low-emission zones, demonstrating characteristics “low-carbon growth”. To peak neutrality targets, must adopt comprehensive measures reduce including strengthening monitoring, implementing differentiated reduction policies, promoting at level.

Analysis of the spatial variation characteristics regional carbon sources/sinks is a prerequisite for clarifying position balance zones and formulating measures to reduce emissions increase sinks. Studies sinks have often used coefficient method, which limited by sample size, measurement error, low resolution. In this study, 31 cities in middle reaches Yangtze River urban agglomerations (MRYRUA) were studied with improved CASA (Carnegie Ames Stanford Approach) model estimate grid-scale net ecosystem productivity (NEP) explore spatial-temporal evolution budgets from 2005 2020. By calculating index (CBI), economic contribution (ECC), ecological support (ESC), zoning was conducted. Corresponding suggestions are based on results. From 2020, increased high north-central region south. addition, sink functional distributed rich resources. Low-carbon shifted Poyang Lake Urban Agglomeration Wuhan City Circle; low-carbon optimization occurred Circle Agglomeration. Carbon intensity control high-carbon rapid development.

The local land use carbon budget (LUCB) balance is an important factor in achieving regional neutrality. As the basic unit of China’s economic development and social governance, county level part realization “double carbon” goal. This paper focuses on 1069 units within Yangtze River Economic Belt (YREB). It utilizes data use, nighttime light, energy consumption, factors to construct emission models. spatiotemporal characteristics LUCB these are analyzed using standard deviational ellipse (SDE) spatial autocorrelation methods. Additionally, a zoning study conducted by examining contribution coefficient (ECC) emissions, ecological support (ESC), their coupling relationship. results show that (1) total emissions (LUCE) increased significantly during research period, sink was relatively stable. (2) spatially high east low west, with center gravity moving southwest as whole. (3) shows positive has significant agglomeration characteristics, which mainly high–high low–low types. (4) ECC ESC west east, coordination degrees two low. (5) According ESC, divided into low-carbon conservation area, comprehensive optimization area. helpful promoting sustainable neutrality YREB.

Spatial planning, recognized as a systematic policy instrument for regional development and governance, plays crucial role in achieving carbon peak neutrality. This study establishes framework sources/sinks estimation compensation optimization conducts empirical research representative coal resource-based city. We analyzed the spatial–temporal distribution characteristics of net emissions Huaibei from 2006 to 2020 using spatial correlation model an improved Carnegie–Ames–Stanford approach (CASA). Then, we applied normalized revealed comparative advantage (NRCA) index SOM-K-means clustering categorize pattern into payment, balance, areas. These areas were further integrated with “Three-zones Three-lines” reclassify nine partition types. Finally, proposed targeted emission reduction sink enhancement scheme. found that urban sinks exhibit significant mismatch, intensity reaching 166.76–383.27 t·hm−2 2020, showing rapid increase followed by stabilization. The high-value area, centered Xiangshan District, exhibits circularly decreasing characteristic, gradually extending central city Suixi County. In optimized payment level contributive coefficient surpasses ecological support (3.92 < ECC 6.04, 2.09 ESC 3.58). space balance area type is primarily situated mining subsidence areas, leading lower overall (0.42 0.57, 0.49 1.13).

In the urgent context of global climate change and carbon neutrality goals, effective balance regulation is critical for achieving temperature control targets. Metropolitan areas encounter significant challenges in emission reduction, energy transition advancement, enhancement sequestration capabilities. However, traditional analysis methods have limitations capturing dynamic changes guiding precise regulation. Therefore, this study developed a dynamic–static classification system based on Ecological Support Coefficient (ESC) Economic Contributive (ECC). This examined emissions China’s 14 national-level metropolitan from 2000 to 2020. The results showed that: (1) Carbon an increasing trend, exhibiting spatial distribution with higher levels north, moderate central region, lowest southeast. contrast, exhibited pattern east, lower west. (2) Static revealed that ECC ESC northern regions were relatively weaker than those other regions. Dynamic further upward trend economic ecological capabilities these areas. along coast within Yangtze River Belt needed optimize their economic–ecological coordination efficiency.
