“…To identify an economy's system-wide dependence on natural gas, the notion of embodied energy can be employed, which is defined as the total energy (direct plus indirect energy use) required to produce and sustain a certain good or service (Chapman, 1974;Costanza, 1980). The concept has been widely applied to investigate embodied energy use at urban scale (Chen et al, 2017b;Li et al, 2014), sub-national scale (Chen et al, 2017c;Gao et al, 2018;Zhang et al, 2015), national scale (Lenzen, 1998;Zhang et al, 2017) and global scale (Gasim, 2015;Kan et al, 2019a;Wu and Chen, 2017). It has been also extended to evaluate individual energy source, such as embodied oil use (Tang et al, 2012;, embodied coal use Xia et al, 2017) and embodied nuclear energy use (Cortés-Borda et al, 2015), as well as many other elements like carbon emissions (Su and Ang, 2015;, methane emissions (Wang et al, 2019;Zhang et al, 2016) and PM emissions (Meng et al, 2016).…”

As an extension of our previous study on natural gas use in world economy (Kan et al, Energy Policy 124 (2019) 215-225), this paper explores policy implications based on a time series analysis uncovering the evolution of natural gas use embodied in global supply chains during 2000-2011. Due to increasing gas supply from gas-rich regions to gas-scarce regions and outsourcing of energy-intensive industries, trade imbalance of embodied natural gas is intensifying globally, corresponding to strengthening gas resource relocation and environmental stress shift. Regarding trade patterns, EU and Russia remain the leading (net) importer and exporter of embodied gas, respectively. And global trade relations are diversifying over time, with more suppliers and recipients joining the international trade. Based on the New Policies Scenario provided by IEA, a long term forecast of embodied gas use illustrates need to prepare for a world with changing energy mix, with respect to growing availability of low-cost natural gas and robust demand growth coming from emerging economies, especially China, who is struggling to fight against air pollution through coal-togas switch. Potential room to expand natural gas utilization is also targeted, and the expansion requires coordination of all the agents in global supply chains.

“…It can be seen that the division of Tapio decoupling is the further development and improvement of the decoupling theory. At present, the Tapio decoupling index has been widely used in related literature [13,[19][20][21]. Therefore, this study uses the Tapio decoupling model to measure the city dematerialization level.…”

“…The dematerialization trend of developed countries or economies may be offset by the resource intensification of developing countries or economies [14]. Hence, at the global level, it is difficult to determine whether dematerialization has occurred in country level or economies [13][14][15]17]. Similarly, due to the different levels of economic development of cities within the country, it is necessary to conduct dematerialization research at city level to judge the development stage of the city [20].…”

Dematerialization is a phenomenon in which resource consumption and pollutant discharge decrease during economic development. In order to explore the optimal paths of Beijing’s dematerialization, this study combines material flow analysis method and the Tapio decoupling model to construct a city dematerialization evaluation model, and establishes a system dynamics model to simulate the comprehensive dematerialization levels and the dematerialization levels of eight materials under four scenarios. The results show that the key factors affecting the dematerialization levels of resource and discharge end were non-metals consumption and CO2 emissions respectively. During 2016–2030, Beijing would achieve weak decoupling state under four scenarios, but the degree of dematerialization would be different. For the comprehensive dematerialization level, during 2017–2024, an industrial restructuring (IR) scenario, which would strengthen R&D investment and optimize the industrial structure, would be the optimal choice. During 2025–2030, an environmental governance (EG) scenario, which means increasing the investment in pollution control, would bring about the best dematerialization level. There would be differences in the optimal dematerialization paths for eight materials. For example, economic sustainable degrowth (ESD) and EG scenarios would be the optimal paths for dematerialization of atmospheric pollutants in the period 2017–2021 and 2022–2030, respectively.

“…It follows from the above considerations that most studies focus on the analysis of decoupling GDP growth from resource use. Only a few studies [12,22,34] examine the use of raw materials while taking into account various categories of these raw materials, such as biomass, non-metallic minerals, fossil fuels, and metal ores. However, to the best of our knowledge, there are only several studies that investigate the problem of decoupling economic growth from fossil fuels on a global scale.…”

Decoupling Economic Growth from Fossil Fuel Use—Evidence from 141 Countries in the 25-Year Perspective

2020

This study offers an in-depth analysis of the decoupling of economic growth from fossil fuel use in 141 countries over the last 25 years. The study is based on the Tapio decoupling approach, and two methods of measuring fossil fuel use, i.e., domestic material consumption (DMC) and material footprint (MF), are applied. Groups of countries with similar decoupling patterns are identified through the k-medoids method. Next, the relationship between these patterns and the level of countries’ development is examined. The results reveal that using different measures of fossil fuel use yields different processes of decoupling economic growth from fossil fuel use. In particular, when the DMC indicator is considered, relative decoupling is observed in most analysed cases. When the MF indicator is applied, the decoupling states of individual countries change more frequently. Finally, in highly developed countries, absolute decoupling is frequently observed, although only when the DMC indicator is used.
