From 2008 to 2014, a steady rise in low-carbon emission regions transpired, with Suining city being a notable beneficiary. The ensuing period, spanning 2014 to 2020, witnessed a stable growth trend in carbon emissions, alongside the emergence of medium emission zones in Guang’an, Suining, and Yibin. Noteworthy, Ya’an and Leshan cities showcased low emissions, owing to their abundant forest resources and a predominant focus on low-emission industries.
County-Level Analysis
Zooming into the county-level analysis, the distribution of carbon emissions across administrative regions offers a nuanced perspective. Counties with high carbon emissions, ranging from 1% to 6%, are primarily concentrated in key areas such as the Shuangliu District and Wuhou District of Chengdu, the Yubei District, and Tongliang District of Chongqing. In contrast, regions with lower industrialization levels surrounding the Sichuan Basin feature prominently as hubs of low carbon emissions, accounting for 21% to 41% of the total.
The evolving spatial structure, as depicted in Figure 5, highlights a transition from a multi-center-periphery layout to a dual-core-periphery configuration over time. Initially, higher carbon emissions were clustered in the central counties, gradually shifting towards the eastern and western core regions. This transformation underscores the dynamic nature of carbon emissions within the CCEZ, reflecting spatial redistribution patterns and evolving emission trends across diverse administrative levels.
In the region encompassing Fucheng District and Jiangyou in Mianyang, Jingyang District in Deyang, as well as Yubei District, Shapingba District, and Banan District in Chongqing, there have been noticeable patterns of carbon emissions over the years. For instance, in 2003, there was an increase in carbon emissions across most counties within the Chengdu-Chongqing Economic Zone (CCEZ), with certain areas like Xindu District, Qingbaijiang, Chenghua District, and Longquanyi District of Chengdu showing higher emissions. Similarly, in 2006, there was a shift in the distribution of carbon emissions from a multicenter to a dual-core pattern, expanding from core areas like Jinjiang District, Shuangliu District of Chengdu, and Yubei District of Chongqing.
Furthermore, by 2014, there was a noticeable growth in carbon emissions, particularly in the central part of the CCEZ, leading to an expansion of regions with medium carbon emissions. However, in 2017, due to the implementation of carbon emission reduction policies, there was a decrease in the overall distribution of carbon emissions in the CCEZ, especially in counties with high and relatively high emissions in the central region. Moving forward to 2020, total carbon emissions continued to rise steadily, with a stable trend in high and relatively high emission counties, indicating a shift towards faster growth rates in surrounding counties driven by development.
Exploring Carbon Emission Dynamics: Spatial Patterns
Understanding the spatial distribution of carbon emissions at a granular level is essential for effective emission reduction strategies.
