The amount of environmental pollution can be caused by several factors. These factors are not in the same position in terms of importance and impact, and not all of them can necessarily be seen together in one place or time. Therefore, the main purpose of this study is to investigate the asymmetric impact of oil prices, foreign direct investment and economic growth on carbon emissions in Iran d...

Given the importance of the issue and the undeniable role of the environment in the community's life, in this research, it is attempted to test the hypothesis of the relationship between the government size and composition of government expenditure (Current and developmental) on carbon dioxide emissions in Iran during 1971-2016 based on autoregressive distributed lag approach. To better explain...

In this study, a contract for vertical and horizontal coordination is developed in which transportation mode and carbon emissions tax play a key role in determining the values of the contract parameters. The contract is designed for simultaneous coordination of cooperative advertising and periodic review replenishment decisions of a supplier and two competitive retailers. To obtain the optimal ...

T he main aim of this study is to investigate the impacts of population total, gross domestic product per capita, urbanization rate and energy use on carbon emissions in Nigeria for a period of 1981-2015 using autoregressive distributed lag approach to co-integration (ARDL). The empirical results revealed evidence of a long run relationship among the variables. The generalized ridge ...

Based on China’s carbon emissions of agriculture, the authors appraise the area differentiation of carbon emissions of agriculture; examine the influential factors of agricultural carbon emissions in China. The results show that the performance of China’s agricultural carbon emissions is on the rise. The agricultural carbon emissions in the west of China increase rapidly. The area differentiati...

Unbalanced use of fossil fuels has made the environmental crisis as major challenge for governments. In the same methods, international and domestic institutions have designed and implemented various policies and plans to reduce greenhouse gas emissions, which are the cause of environmental pollution. One of the successful policies to reduce emissions is carbon tax policy. Considering the envir...

this work investigates the effect of the application rate and type of sludge throughout the soilcarbon cycle in a semiarid mediterranean agro-ecosystem. we study the two-year evolution of the variouspools of soil organic and inorganic carbon and their influence on soil respiration. we applied three rates (40, 80 and 160 mg/ha) of two types of sludge –aerobically and anaerobically digested sewag...

Mining is among the oldest industries. It is the primary source of raw materials for most of the sectors. Little is known about the complex inter-sectoral carbon linkages of the mining industry. In this work, we estimate the inter- and intra-sectoral carbon linkage impacts of the mining sector across ten major economies by applying an input-output model, and the hypothetical extraction method a...

In this study, an attempt is made to investigate the effect of energy consumption on environmental pollution in Iran. For this purpose, a basic model (the whole economy) and three sectoral models (household, commercial and public; industry and transportation) has been estimated with an autoregressive distributed lag approach in the period 1971-2017. The results of the model estimation show the ...

Abstract: The gradual warming of the earth and its negative environmental and economic impacts contributed to pay attention to sustainable development considerably. Since climate change is a major cause of greenhouse gas emissions, including CO2, countries are seeking to prevent the rapid growth of emissions to reduce global climate change. Accordingly, and considering the importance of the sub...
