How much carbon dioxide is produced when different fuels

The amount of CO 2 produced when a fuel is burned is a function of the carbon content of the fuel. The heat content or the amount of energy produced when a fuel is burned is mainly determined by the carbon (C) and hydrogen (H) content of the fuel. Heat is produced when C and H combine with oxygen (O) during combustion. Natural gas is primarily methane (CH 4), which has a higher energy content Get price

Specific carbon dioxide emissions of various fuels

Fuel is not equal to fuel - at least if we consider carbon dioxide emissions. Burning of lignite emits nearly 100 % more carbon dioxide with respect to the energy content than burning of natural gas. Even natural fuels such as wood or peat have high specific emissions, if they are not used sustainable. Hence, deforestation has a high impact on Get price
