No, they do not. They produce clean energy.
Methane burns in oxygen and gets oxidised. Carbon is oxidised to carbon dioxide, hydrogen to water.
CO2 (Carbon Dioxide) for the most part, but the components of the original air that was inhaled are still present, although the O2 (oxygen) component will be reduced.
Methane is practically the same as natural gas. When 1 molecule of methane (CH4) is burnt in oxygen it produces 1 molecule of carbon dioxide (CO2) and two molecules of water (H2O). If the methane is NOT burnt it causes twenty times more damage as a greenhouse gas than carbon dioxide. (So keep lighting those farts!)
When methane burns, the carbon dioxide and water formed, equal the mass of the methane plus the mass of the oxygen.
Water is H2O, ammonia is NH3, carbon dioxide is CO2 and methane is CH4.

Methane from their rear end and carbon dioxide and all the stuff they breathed in from the mouth

methane
Several processes release carbon as gases (carbon dioxide, carbon monoxide, methane) into the atmosphere. Three important processes are fuel combustion, respiration, and methane release. -- Combustion of carbon-based fuels (wood, alcohol, biogas, or fossil fuels) remove oxygen and combine it to form carbon dioxide and other compounds. -- Plant and animal respiration release carbon dioxide. This is the reverse operation of photosynthesis. -- Methane is released from ruminant animals, from decomposition of organisms, and from ocean-bottom clathrate deposits.
When carbon is burnt, Carbon Dioxide only is produced. When methane is burnt, both carbon dioxide and water are produced.
When methane is completely combusted, 1 mole of methane yields 1 mole of carbon dioxide. So, if 1 liter of methane gas is burned, it would produce 1 liter of carbon dioxide gas.
I think carbon dioxide but definitely a bowel gas which can be deadly sometimes
