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...

air pollution is one of the major issues is the use of fossil fuels. air pollution in different ways harmful effects of long-term, short-term, devastating and sometimes irreversible in humans, animals and plants life. air pollution leads to increased heart disease, breathing, decreased vision, warming, acidification, etc. one of the problems of air pollution. air pollution threatens the surviva...

greenhouse gas emissions are considered as the main cause of climate change. investigation of economic dimensions of greenhouse gas emissions and its environmental effects especially in a situation where the volume of greenhouse gas increasingly is rising is very important. in this paper, the relationship between greenhouse gas emissions i.e. carbon dioxide and gdp per capita and energy consump...

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...

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...

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 ...

Biomass burning is a major source of emissions to the atmosphere. Some of these emissions may change global climate. This paper uses combustion eff iciency as an independent variable for predicting emission factors for, among others, carbon monoxide, carbon dioxide, methane, and particulate matter. Other gases are correlated with the release of carbon monoxide. The release of nitrogen and sulfu...

Issues related to environment are one of the most important issues that confront communities in recent decades.   Resource scarcity and the necessity of development for Iran and other similar countries requires us to deal with carbon dioxide emissions as a manifestation of environmental crisis. In this study, we assess the relationship between carbon dioxide emissions as a dependent variable wi...

abstract ion selective electrodes (ises) are electrochemical sensors that respond selectivity to the activity of ionic species. an ion-selective electrode is an electrochemical device that uses a thin selective membrane or film as the recognition element, and is an electrochemical half-cell equivalent to other half-cells of the zeroth (inert metal in a redox electrolyte). in common methods o...

this study investigates monthly and seasonal variations of carbon emission from the soil at different grazing intensities. three areas of exclosure, low and high grazing intensities were selected in ghoosheh region of semnan province. carbon emission was measured monthly, in each treatment applying alkali traps (csc) during a year. emission and grazing data were analyzed, using a factorial expe...
