It depends on how the trash decomposes. If it is being consumed by aerobic bacteria (oxygen needing) it is likely carbon dioxide (CO2). If the trach is decomposed by anaerobic bacteria (non oxygen metabolism) it is lekely methane (CH4). If eathen by termires and such is is methane again. In all cased there is some water (H2O) emitted, another greenhouse gas.
Decomposition may release several gasses depending on the material being decomposed and the conditions. This include:
METHANE
Ozone acts as a greenhouse gas too. It traps the heat emitted from the sun and does not allow it to exit.
carbon-dioxide.
water vapor
water vapor
The main greenhouse gas emitted from burning diesel, a fossil fuel, is carbon dioxide (CO2).
Away from air (under anaerobic conditions) decomposing organic trash releases methane gas. If air is present the trash releases carbon dioxide gas. In both cases organics and sulfides may be present that contribute odours to these gases.
China has recently overtaken the US in the annual production of greenhouse gas emissions.The US is still the leader in the long-termamounts of pollution emitted.
Ethanol is a liquid at normal ambient temperatures and is not a greenhouse gas. However, when ethanol is used as a fuel in a vehicle, CO2 (carbon dioxide) is emitted. CO2 is considered a greenhouse gas in that as it builds up in the atmosphere, it has the same effect as the glass roof of a greenhouse. It allows energy from the sun to enter the earth's atmosphere but prevents some of it from being re-emitted back into space. The net effect is that the temperature begins to rise, just as in a greenhouse.
The atmospheric lifetime is important because it helps to determine the long-term impact of the greenhouse gas. If there are efficient environmental removal mechanisms for a greenhouse gas (that is, if it has a short atmospheric lifetime) the gas will accumulate in the atmosphere more slowly than predicted by the rate at which it is emitted. If a greenhouse has a longer atmospheric lifetime, then even though not a lot of it is emitted from various sources, the atmospheric concentration of the gas will continually increase, allowing the gas to contribute to global warming for a long time.
The burning of any fossil fuels emits carbon dioxide, a greenhouse gas.
Carbon dioxide (CO2), a greenhouse gas, emitted by cars and vehicles and power stations.
