The Minamata Convention on Mercury calls for Hg control actions to protect the environment and human beings from the adverse impacts of Hg pollution. It aims at the entire life cycle of Hg. Existing studies on the Hg cycle in the global environmental–economic system have characterized the emission-to-impact pathway of Hg pollution. That is, Hg emissions/releases from the economic system can have adverse impacts on human health and ecosystems. However, current modeling of the Hg cycle is not fully looped. It ignores the feedback of Hg-related environmental impacts (including human health impacts and ecosystem impacts) to the economic system. This would impede the development of more comprehensive Hg control actions. By synthesizing recent information on Hg cycle modeling, this critical review found that Hg-related environmental impacts would have feedbacks to the economic system via the labor force and biodiversity loss. However, the interactions between Hg-related activities in the environmental and economic systems are not completely clear. The cascading effects of Hg-related environmental impacts to the economic system throughout global supply chains have not been revealed. Here, we emphasize the knowledge gaps and propose possible approaches for looping the Hg cycle in global environmental–economic system modeling. This progress is crucial for formulating more dynamic and flexible Hg control measures. It provides new perspectives for the implementation of the Minamata Convention on Mercury.

“…In compliance with input-output analysis, Schultz [43] analyzed linkages among 20 standard sectors for the first time using hypothetical extraction method (HEM), this method suppose that a sector is eliminated and then compare total output changes in the economic system before and after the removal of this sector, aiming to measure the importance of this sector in the whole economic system and quantitatively analyze impacts on other sectors. HEM is generally applied to research the economic effect of a sector [42][43][44][45][46][47][48], and identification of a key sector to formulate targeted policies based on the analysis results [49][50][51][52], even extended to resource consumption and carbon emission research fields to analyze the linkages of resources consumption and carbon emission of different countries or regions [53][54][55][56][57][58]. On the foundation of HEM, Duarte et al [59] pointed out that modified hypothetical extraction method (MHEM) calculates the vertically integrated consumption and divide linkage effect into four components which aims to analyze the linkage of water use in Spain.…”

The purpose of this paper is to explore the relationships between the construction sector and the rest of the Chinese economy in the energy consumption as it is crucial in energy consumption of the whole economy. Therefore, this paper uses the Modified Hypothetical Extraction Method (MHEM) to quantify the linkages of energy consumption in 2002, 2005, 2007, 2010, 2012, 2015, 2017 and 2018, providing a new perspective for energy consumption linkage studies in China. In this paper we discover the volumes and paths of energy consumption net flows from other blocks to the construction sector and identify the key energy suppliers of the construction sector. The empirical findings show that the indirect energy consumption exceeded the direct energy consumption between 2002 and 2018, representing more than 90% of total (direct plus indirect) energy consumption of the construction sector. Between 2002 and 2018, the indirect energy consumption of the construction sector increased from 27,579 to 111,760 × 104 tons of coal equivalent (tce). We further find that the construction sector has the largest inflows of energy consumption to obtain its own demand than other sectors from 2002 to 2018. The average annual energy consumption net flows from other seven sectors to the construction sector were 1477, 687, 47,998, 6067, 1483, 7362 and 1923 × 104 tce in 2002–2018, respectively. Moreover, we find that the Manufacturing sector is the largest energy supplier of the construction sector between 2002 and 2018.

“…As the largest Hg emitter in the world (UNEP, 2019), China plays an essential role in the global Hg cycle, and has been the target for many studies on Hg emissions. Studies on China's Hg emissions have been devoted to compiling national and regional Hg emission inventories (Hu et al., 2018; K. Liu et al., 2018; Q. Wu et al., 2016; Z. Wu et al., 2020; L. Zhang et al., 2015), exploring the trends of Hg emissions in China from different perspectives (e.g., demand and supply) (H. Zhang et al., 2018), revealing the impact of trade on Hg emissions (L. Chen et al., 2018; He et al., 2021; Li et al., 2017; Zhang et al., 2018), and evaluating the effect of air pollution control measures on Hg emissions (Q. Chen et al., 2022; K. Liu et al., 2019; Zhao et al., 2015). Studies have also investigated the impact of economic development on Hg emissions in China during different periods.…”

China is important in the global mercury (Hg) cycle and is experiencing substantial economic structure transitions. There are pronounced differences in economic development, industrial structure, and consumption patterns across regions in China. However, the impacts of regional economic structure transitions (i.e., production and final demand structures) on Hg emissions in China remain unknown. Here, we reveal the transboundary impacts of changes in regional economic structures on provincial Hg emissions in China. We found that the transitions of production and final demand structures in coastal regions led to Hg emission reductions in China during 2007–2017. In particular, production structure changes in East Coast contributed to 36 metric tons of national Hg emission reduction, where 28 metric tons occurred in other regions (especially Hebei). Its final demand structure transition contributed to 19 metric tons of national emission reduction, where 15 metric tons occurred in other regions (especially Henan). Unfortunately, production structure changes in Northwest and final demand structure changes in Southwest contributed to Hg emission increments in China during 2007–2017. For instance, changes in the final demand structure of Southwest caused 34 metric tons of emission increments, mainly from provinces within the region. Thus, spatially explicit measures for China's Hg emission control can focus on the optimizations of production structure in Northwest and final demand structure in Southwest, as well as the promotion of interregional joint actions between East Coast and North China (especially Hebei and Henan). The findings of this study can inform region‐specific policy decisions and interregional joint efforts to control Hg emissions around the world.
