Abstract

The low-carbon city pilot (LCCP) policy constitutes a crucial element in China’s endeavors to attain its carbon peak target. Thoroughly analyzing the carbon abatement effects and mechanisms of the LCCP policy is essential for supporting China’s goals of achieving low-carbon sustainability. We use panel data from 1997 to 2019, covering 249 Chinese cities, for a quasi-natural experiment. This study assesses the effect of the LCCP project on urban carbon emission intensity (CEI) using a difference-in-difference (DID) model. Furthermore, the article conducts analyses on policy coordination effects, impact mechanisms, and spatial spillover effects. Our research findings indicate that the LCCP policy substantially decreases urban CEI, a result that withstands a battery of robustness tests. The carbon abatement effect of LCCP policies is dynamic and typically endures for three years. Subsequent investigations unveil a cooperative impact between the LCCP policy and the carbon trading pilot policy. The decrease of urban CEI under the LCCP policy is primarily attributed to command and market tools, although the efficacy of voluntary tools remains unrealized. From the standpoint of adjacent nonpilot cities, our conclusions do not endorse the presence of spatial spillover effect for the LCCP project. The insights derived from our findings offer crucial guidance for policymakers exploring low-carbon models and pathways. [ABSTRACT FROM AUTHOR]

Abstract

With the continuous expansion of regional trade, interregional teleconnections have an increasingly pronounced impact on the changes in carbon storage caused by land use in China. Current research in this area remains remarkably limited, however. This study employs land-use data, carbon density data, and a multiregional input–output model to precisely quantify the embodied flow and spatial patterns of land-use carbon storage in China. We found that the carbon storage embodied in interprovincial trade in China accounts for 34.9 percent of total carbon storage, with cropland (44.9 percent) and woodland (43.6 percent) representing the highest proportions within their land-use categories. Inner Mongolia, Heilongjiang, and Tibet were found to be the most externally driven in terms of land-use-related carbon storage, with outflows exceeding 2,000 Tg C. Beijing, Tianjin, and Shanghai, on the other hand, were shown to consume up to 90 percent of land-use-related carbon storage inflows, showcasing the strongest external dependence. Additionally, Hunan (1,300.5 Tg C), Hubei (863.4 Tg C), Henan (1,534.6 Tg C), and Shanxi (2,223.6 Tg C) are the provinces where changes in land-use carbon storage are most significant, exerting the greatest influence on changes in China's total carbon storage. China's international export of land-use-related embodied carbon storage decreased by 3,964.7 Tg C during the study period, with woodland (1,516.8 Tg C) and grassland (1,505.7 Tg C) being the primary declining land types. Interestingly, as land utilization efficiency continues to rise, over half of the provinces have seen an increase in export trade value, while their corresponding embodied carbon storage has declined. The findings not only unveil the complex dynamics and spatial distribution at work in China's embodied land-use-related carbon storage but also provide practical insights and directions for achieving carbon neutrality goals.
