Introduction: Carbon stored in soils particularly in arid rangelands soils is the most significant carbon sink in terrestrial ecosystems. In arid rangelands, Soils have special places in both carbon sequestration and mitigate global warming. Therefore, any small change in the soil organic carbon (SOC) leads to a significant impact on the CO2 concentration in the atmosphere. Studies have shown t...

According to released official statistics of greenhouse gas emissions in 2010, CO2, which is produced by fossil fuels and industrial processes, accounts for 65 percent of total global greenhouse gas emissions. The transport sector, in turn, is responsible for 23% of CO2 emissions. Researchers have been claiming that car manufacturers have not made significant efforts to reduce the pollution lev...

In recent decades, rising greenhouse gas emissions have become a major challenge and concern. Environmental pollution is one of the greatest human challenges of the 21st century. Improving the performance of internal combustion engines and reducing the amount of pollutant emissions has always been a concern for researchers. The use of alternative fuels and the control and adjustment of the lamb...

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...

Achieving sustainable economic growth is one of the most important goals of countries' economic programs and policies in the current era. Along with economic growth, consumption of energy rises. Since fossil fuels provide a major share of the world's energy, increased fuel consumption is an inevitable feature of economic growth.  Continuation of this trend increases greenhouse gas emmissions, n...
