“…From a spatial perspective, areas with high carbon emission contributions and economic development are often located in important water source areas, major river basins, and coastal areas, consistent with the findings of Xiong et al [64]. The payment areas are faceted on the northern shore of Taihu Lake, the southern shore of the Yangtze River, and the eastern coast, a phenomenon related to economic, policy, and geographic factors.…”

As a world-class urban agglomeration, the Yangtze River Delta urban agglomeration is significant for China’s carbon neutrality strategy when calculating the carbon budget and dividing carbon compensation zones. This paper focused on 129 county-level cities in the core area of the Yangtze River Delta urban agglomeration, calculating the carbon budget for 2000–2020 using night-time light data and analyzing the evolution of spatiotemporal patterns. On this basis, a carbon compensation zoning model was constructed using the K-means algorithm; 129 cities were divided into different carbon compensation zones after combining this model with the main functional zones. The results showed that (1) the carbon emissions increased, with overall stabilization after 2012. The distribution of high carbon emission areas evolved from a “core-periphery” pattern into a “Z-shaped” pattern. Ecological carbon sinks showed a continuous decline, with the southern sinks performing better than the northern ones. (2) The carbon budget of the study area showed a deficit, gradually widening and exhibiting an unbalanced spatial distribution characterized by a “high in the south and low in the north” pattern. (3) Eleven types of carbon compensation zones were designated after overlaying the main functional zones. Low-carbon development suggestions were proposed for each zone type.

“…Although carbon balance zoning in this study was similar to that of Xiong's, it differed in the selection of zoning indicators. Xiong used the carbon productivity to measure regional carbon emissions from the perspective of economic benefits, while we used the ECC to characterize regional carbon productivity [44]. This indicator is more consistent with the energy utilization rate among cities within the MRYRUA.…”

“…The ESC is the quotient of the ratio of carbon absorption of a certain unit to carbon absorption of the whole region and the ratio of carbon emission of the unit to carbon emission of the whole region [44]. It reflects the strength of regional carbon sequestration capacity from the perspective of carbon balance.…”

“…Carbon balance analysis and zoning has become an important research field in the context of global climate warming [41] and China's "double carbon" targets [42]. Most studies rely on indicators affecting the regional carbon balance to establish functional zoning and make low-carbon policy recommendations [43,44]. Vaccari et al conducted a carbon balance study for the city of Florence and found that green spaces offset 6.2% of direct carbon emissions, which informed subsequent development planning in the city [45].…”

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

“…Nevertheless, due to factors such as uneven economic development and disparities in natural resource endowments across China, the development degree of forest carbon sinks varies between regions, and there are significant differences in the coordination of different benefits. To achieve a regionally balanced development of forest carbon sinks, effective performance management systems have been implemented in various regions [4]. In terms of performance management, efficiency measures are designed to provide quantitative information on the performance of the evaluated object, enabling horizontal performance comparison as well as vertical performance monitoring.…”

Forests have multifunctional roles. They not only increase forest carbon sinks through afforestation and management, but also indirectly realize multiple benefits of "economy + ecology + society". Therefore, we construct a multiple output-benefit system of forest carbon sinks based on the development of forest carbon sinks in provinces of China. This system is also able to distinguish the importance of forest carbon sinks from other outputs. For the efficiency evaluation of multi-level output systems, this paper constructs a cross-evaluation model based on evidential reasoning method, the original efficiency information by conducting efficiency evaluation before information fusion. Further, the spillover effects and influencing factors of forest carbon sink efficiency are analyzed through a spatial regression model to explore the spatial characteristics of forest carbon sink efficiency in China. The results show that: (1) there is a large gap between the cross-efficiency levels of forest carbon sinks in various regions of China, with significant spatial correlation. For the perspective of direct output benefits, the cross-efficiency of the eastern region is higher, while the cross-efficiency of the northwestern region is lower; for the perspective of indirect output benefits, the cross-efficiency of the southeastern region is higher. (2) China's forest carbon sink has a significant positive spillover effect, and the indirect output cross-efficiency has a significant negative impact on the forest carbon sink in its own region. Further analyzing the impact of indirect output cross-efficiency, it is found that the cross-efficiency of the ecological dimension and the cross-efficiency of the social dimension have a significant negative impact on the forest carbon sink in its own region, and the economic dimension has a significant positive impact on the forest carbon sink in its own region. In conclusion, corresponding policy recommendations are proposed for the development of forest carbon sinks to promote the realization of the dual-carbon goal.
