Bikes don't emit any greenhouse gases. Unless you want to get really technical and trace the calories that you burn to power the bike back to the carbon footprint of the food they came from.

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.
Carbon dioxide (CO2), a greenhouse gas, emitted by cars and vehicles and power stations.
Emissions means "what comes out", or "what is released".When we talk about greenhouse gas emissions we are usually referring to carbon dioxide, which is emitted when we burn fossil fuels. It can also refer to methane, another greenhouse gas, which is emitted from cattle and from melting tundra.its is emissions from cars , fridges, factory's it goes into the atmosphere and coats things such as tree's and they cut the trees down and then it is less oxygen
A greenhouse gas is a gas in the atmosphere that takes in and releases radiation. The greenhouse effect is more of a process in which radiation is emitted in different directions after being absorbed by greenhouse gases.
METHANE
Ozone acts as a greenhouse gas too. It traps the heat emitted from the sun and does not allow it to exit.

The main greenhouse gas emitted from burning diesel, a fossil fuel, is carbon dioxide (CO2).

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.
