“…Since mid-twentieth-century climate, scientists collected the detailed observations on weather phenomena. And, the study revealed that global surface temperature would raise between 3 and 4°C by 2100 if the carbon emissions continue at their current rate (https:// www.britannica.com/science/global-warming) to meet the countries' energy demand by burning fossil fuels (https:// www.britannica.com/science/global-warming) (Sabouni et al 2014;Deng et al 2020;Naims 2016). A new study by the NASA researchers (Environmental Research Letters) had confirmed that global warming is heating up the planet by measuring the Earth's skin temperature using the atmospheric infrared sounder (AIRS) technique (https://www.eurekalert.…”

The anthropogenic carbon dioxide (CO 2 ) denseness in the earth's atmosphere is increasing day-to-day by combusting fossil fuels for power generation. And, it is the most important greenhouse gas (GHG) responsible for 64% of global warming. Solvent-based carbon capture gained more attention towards researchers because of its easiness to integrate with the coal-fired power plant without significant modifications. During CO 2 absorption, the physical property of the solvent gets changed. A change in the solvent's physicochemical property affects further CO 2 absorption, thereby increasing the carbon-capture energy demand. The present experimental study encompasses CO 2 absorption studies using 30 wt% aqueous monoethanolamine (MEA), 2-amino-2methyl-1-propanol (AMP) and piperazine (PZ) followed by the detailed analysis of physicochemical properties (pH, carbon loading (α), viscosity (μ), density (ρ) and surface tension (σ)) of various CO 2 -loaded solutions. The results revealed that these properties are exhibiting interdependent eccentrics. Furthermore, an empirical model was developed to predict the carbon loading of the tested solvents. This model includes the tested physicochemical properties, reaction mixture temperature, diffusivity and change in the mass of solvent during carbon loading. In addition, an empirical model for viscosity as a function of temperature, carbon loading and molecular weight of solvents was developed. These models appear to predict the carbon loading and the viscosity well with greater accuracy.Keywords CO 2 capture . Carbon loading . Diffusivity . Viscosity . Surface tension .

“…The explanation of this fact from a chemical view is straightforward: the carbon component of non-renewable energy is converted into carbon dioxide during the combustion process. In this context, other scholars have found that the industry structure and technological level can reduce the CO2 emissions from non-renewable energy consumption (Al-mulali, Lee, Mohammed & Sheau-Ting, 2013;Han & Chatterjee, 1997;Lantz & Feng, 2006;Hogan & Jorgenson, 1991;Sohn, 2007;Deng, Alvarado, Toledo & Caraguay, 2020). The former ndings of industry structure and CO2 emissions are also con rmed in studies using China as a context (Zhou, Zhang & Li, 2013;Zhang, Liu, Zhang & Tan, 2014;Wang, Wu, Sun, Shi, Sun &Zhang, 2019;Guan, Meng, Reiner, Zhang, Shan & Mi et al, 2018), as well as technological level and CO2 emissions (Ang, 2009;Wang, Zeng & Liu, 2019;Yunfeng & Laike, 2010).…”

BackgroundWith the economic development, China has become the world's largest CO2 emitter. Given that climate warming has increasingly become the focus of the international community, Chinese government committed to reducing its CO2 emission intensity substantially. Prior studies find that the evolution of economic structure and technological progress can reduce CO2 emissions, but lack of considering CO2 emissions and output as a whole. In addition, the role of education expenditure is relatively overlooked. This paper contributes to the literature by examining the link of CO2 emission intensity, non-renewable energy consumption and education expenditure in China during 1971-2014. ResultsWe use the ARDL approach and find that in the long run, every 1% increase in non-renewable energy consumption results in a 0.92% increase in CO2 intensity, while every 1% increase in operational education expenditure reduces the CO2 intensity by 0.86%. In the short term, 36% of the deviation from the long run equilibrium is corrected in the next period.ConclusionsWe draw out two important conclusions and make important policy recommendations. First and foremost, as long as the increase in operational educational expenditure exceeds the increase in non-renewable energy consumption, CO2 intensity of real GDP will decrease in the long run. This means that in the development stage when economic activities are still highly dependent on non-renewable energy sources, the Chinese government should continue to vigorously increase expenditures on public education. Second, the increase in non-renewable energy consumption will result in an increase in CO2 intensity of real GDP. Therefore, gradually increasing the proportion of clean energy consumption in the energy nexus is another powerful starting point for China to achieve its goal of reducing CO2 intensity of real GDP.JEL ClassificationC32.

“…It is because the countries need to meet their electricity demand, which requires them to burn more fossil fuel than switching to renewables. Deng et al [4] also argued that the use of non-renewable is increasing in South America due to increasing urbanization and economic growth in the region. It raises a need for South American governments to focus more on acquiring higher renewable energy levels to meet the sustainable economic growth requirements.…”

The present research investigates the environmental effects of trade, Renewable Energy Consumption (REC), and industry value-added in South America, doing spatial analyses from 1990-2018. The income per capita has a positive effect on the local CO 2 emissions. Further, it has negative environmental spillovers in neighboring countries regarding consumption-based CO2 emissions but not in terms of territory-based CO 2 emissions. Exports have negative and positive effects on consumption and territory-based CO 2 emissions, respectively. Moreover, exports carry positive environmental spillovers in neighboring countries in case of both consumption and territory-based CO 2 emissions. Imports have a positive effect on consumption-based CO 2 emissions but could not affect territory-based CO 2 emissions. Industry value-added has negative environmental spillovers in the case of consumptionbased CO 2 emissions. REC helps to reduce consumption and territory-based CO 2 emissions in both local and neighboring countries.
