### Calculation Results and Analysis of Carbon Footprint Pressure Index
#### 3.2.1 Temporal Variation Characteristics of the Carbon Footprint Pressure Index
With regard to the factor of accelerated economic development, all counties and districts were vigorously seeking opportunities for industrial upgrading and economic expansion. The industrial sector, in particular, witnessed remarkable growth. For instance, in Quyang County, the local ceramic and building materials industries successively expanded their production scales in an attempt to increase their market shares. They constructed additional production workshops and production lines, which led to a significant spike in the demand for energy resources like coal and electricity during the production process. This, in turn, resulted in a rapid escalation of carbon emissions. Kangbao County, which had primarily relied on traditional agriculture and animal husbandry, also began to gradually introduce processing and manufacturing enterprises during this period. Although these enterprises contributed to economic growth to some extent, their relatively limited technological capabilities and low energy utilization efficiency in the production process inevitably led to an increase in carbon emissions. Many similar scenarios repeatedly played out in various counties and districts, jointly fueling the upward trend in the carbon emission footprint pressure index. However, from 2015 to 2020, a turning point emerged, and the carbon footprint pressure index showed a slight downward trend. This positive change is, in fact, a direct manifestation of the growing awareness of ecological protection within the region and the effective implementation of corresponding policies. An increasing number of counties and districts have come to recognize that economic development should not be achieved at the expense of the ecological environment. Consequently, they have adopted a series of practical measures in succession. For instance, to enhance awareness of ecological protection, various regions have initiated a wide array of environmental publicity activities aimed at helping residents develop a deeper understanding of the ecological environment's significance for quality of life and sustainable regional development. Residents have begun to voluntarily participate in environmental protection initiatives, such as waste sorting and energy conservation. Educational institutions, community groups, and various organizations have proactively engaged in public welfare initiatives, such as tree planting and ecological restoration. These efforts have significantly enhanced the vegetation coverage in the region, bolstered the carbon sink capacity of the ecological system, and facilitated the absorption and sequestration of increased levels of carbon dioxide, thereby mitigating the pressure associated with carbon footprints. In the aspect of policy implementation, government departments have played a powerful guiding role. Local governments have successively introduced stringent environmental access systems, imposing strict restrictions on high-energy-consuming and high-polluting enterprise projects. They no longer blindly pursue economic growth indicators but instead place greater emphasis on the quality of green development. Concurrently, there has been an intensified effort to promote clean energy initiatives, which includes encouraging both businesses and residents to adopt renewable energy sources, such as solar and wind energy. Additionally, enterprises have been incentivized to implement energy-saving technological transformations and enhance energy utilization efficiency through the provision of subsidy policies. These combined efforts have contributed to the gradual decline of the carbon footprint pressure index.
