Due to increasing energy demand, energy has developed rapidly without the problem of environmental protection. Total energy demand in 2030 will be about 50% higher than in 2003, and oil will be about 46% higher. Known oil proven reserves can sustain current levels of consumption only until 2040, and the gas until 2070, while world reserves of coal provides for more than 200 years to an increase in the level of operation. It is estimated that about a quarter of primary energy resources globally, will be covered further in coal. Along with increasing energy consumption will increase consumption of coal. This paper presents criteria for assessing the physico-chemical characteristics of solid fuels in the context of CO2 emissions. From the experimental laboratory research were highlighted as key parts for coal composition are organic massinorganic mass and water. Knowing ash content and the amount of moisture we can estimate the energy value of a fuel conjunction with carbon content present in the coal fuel.Solid fuelsCoal fuelCarbon dioxide emissionsSymposium Proceedings
