Carbon dioxide is presently the most important anthropogenic greenhouse gas, and in contrast to the other greenhouse gases, the human potential to rise its future atmospheric concentration seems to be very high, since the fossil carbon resources (coal, oil, natural gas) probably exceed 6.5 × 1012 tons (6,500 Gt) of carbon.
Among the greenhouse gases, carbon dioxide (CO2) is the most important one and is responsible for more than 60% of the greenhouse effect.
The principal evolving gas in the process is CO2, which is also central to the greenhouse effect.
Some of the byproducts that are emitted as waste from this process, such as methane, act as greenhouse gases which greatly contribute to global warming.
It is obvious that greenhouse gases and air pollutants are mainly emitted from same sources.
Such activity emits large amounts of greenhouse gases, predominantly methane, and is also responsible for an important part of the total geologic carbon flux to the atmosphere.

Most of the important greenhouse gases and tropospheric oxidant gases have significant natural sources, which are not well defined today and may be changing; and thus, quantifying the role of combustion is difficult.
Results indicate that ventilation air methane is a key fraction of the total emissions of greenhouse gases releases in this activity (60–70%).
If current practices continue, atmospheric increases are likely for the greenhouse gases carbon dioxide, methane, nitrous oxide; and for the chemically active gases nitric oxide, sulfur dioxide,and ammonia.
Further results show that CO2 emission is the primary source of greenhouse gas pollution which is 71% of the total CO2 equivalent.
The released gas may enter the atmosphere, and contribute to greenhouse warming.
Natural gas has highest hydrogen-to-carbon ratio among hydrocarbon fuels, which helps in reducing greenhouse gas emissions.
), may contribute to budget of globally nature-derived greenhouse gases.

On a per molecule basis, it is much more effective a greenhouse gas than additional CO2.
The greenhouse with CO2 supplied from bottles turns out to be superior to tthe greenhouse with CO2 supplied by burning gas.
