The word emission generally means sending something out. It can be used in the following contexts:
- In common usage, emission is most often the giving off of gases from industrial processes and the engine exhausts of transport vehicles (automobiles, trucks, airplanes, trains and ships). As they occur on an industrial scale, even relatively harmless gases can have an undesired effect (such as carbon dioxide contributing to the greenhouse effect). See also emissions trading, AP 42 Compilation of Air Pollutant Emission Factors, automobile emissions control, greenhouse gas, and pollution.
- In chemistry emissions are the products of a reaction, either chemical or nuclear.
- In physics and physical chemistry emissions are outputs of electromagnetic radiation or particles.
- In physics, emission theories assumed that light leaves the object that emits it at a particular speed. This idea is most commonly identified with Isaac Newton and Walter Ritz.
- In the history of optics, light was supposed by adherents of emission theory (vision) to be emitted by the eyes. Visual perception was accomplished by such rays of light acting like feeling hands

People have been blaming livestock for methane gas emissions rising to dangerous levels. Turns out it was @mandarella92 go figure.

RT @greenrobeen: more than 50 % of global CO2 emissions come from livestock at feedlots - methane gas along with feed growin' and transport.

Methane Emissions from livestock - A few facts about animal emissions.
Ruminant Livestock Efficiency Program - US EPA - Ruminant livestock such as cattle and sheep are the largest source of methane emissions resulting from human activity. Methane is a potent greenhouse gas. RLEP is a joint EPA-USDA program helping livestock producers improve their operations' efficiency, preserve natural resources, and reduce methane emissions.
Meta Description: [ The site presents information on the sources and quantity of emissions of non-CO2 gases by gas and by sector as well as the costs of mitigation in the US and internationally. In addition, the site presents scientific background and other useful links to information related to non-CO2 gases. ]
Study: Fish Oil Stifles Greenhouse Gas - CNN reports that Belgian scientists found that adding fish oil to animal fodder could cut livestock release of methane.
Meta Description: [ Fish oil could be the answer to stifling the release of the greenhouse gas methane from belching farm animals. ]
