Global warming is considered a problem caused by combined worldwide greenhouse gases (GHG) emissions. Many greenhouse gases occur naturally as a result of Earth's geological, hydrological, and biological cycles. They include water vapor, carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and ozone (O3). In addition, other photochemically important gases, such as carbon monoxide (CO), oxides of nitrogen (NOx), and non-methane volatile organic compounds (NMVOCs), while they do not function as greenhouse gas, contribute indirectly to the greenhouse effect (Anonymous, 1998; ICF, 2007).

As the world proceeds into the 21st century, international dimensions of environmental problems have become more apparent and increasingly important. Globalization of the economy, emergence of worldwide communication and information networks, and rapid development of bio- and nanotechnologies all have important consequences for the environment. One may expect that by the middle of this century about 10 billion people will be placing stresses on the world's natural resources which will lead to further environmental problems (Dincer 2003). In fact, future environmental problems arise not only from the exhaustion of natural resources but also from how those resources are consumed. New technologies can and will lessen damaging environmental impacts if they are employed wisely, guided by the market system under some main pillars, such as better efficiency, better cost-effectiveness, better use of energy resources, better environment, better energy security, and better sustainable development.

From the perspective of energy security and environmental sustainability, highly effective uses for fossil fuel in energy industries are demanded. Power plants having integrated gasification combined cycle (IGCC) with advanced configurations are being developed worldwide to use coal and biomass more efficiently and thus cleanly. Gasification forms the major component within the IGCC systems and has the best fuel flexibility of any of the advanced technologies for power production, with the current technology well adapted to use biomass and other low-value feedstock that have high-ash residues (Liu and Niksa, 2004). Gasification also provides an opportunity to control and reduce gaseous pollutant emissions, and a lowest cost approach to concentrate the carbon dioxide at high pressure to facilitate sequestration (Trapp, 2005).

Energy is a mainstay of an industrial society. It is, therefore, not surprising that many important organizations have attempted to analyze the future need for energy and the availability of various energy sources. Energy consumption growth is closely linked to population growth, although changes in life styles and efficiency improvement have a substantial influence on the per capita annual consumption. The structure of population and the share between urban and rural populations also affect energy demand (Torjman and Shaaban, 1998). Source

Since historical times mankind is dependent on the use of fossil fuels. The exploitation and use of fossil fuel grew exponentially in the last two centuries when world experienced the industrial development. This period was characterized by extensive combustion of petroleum, natural gas, coal and as a consequence there are produced visible unbalances in the natural environment, especially due to the associated CO2 emissions.
