What are the global emissions by gas?
Global Emissions by Gas. Nitrous oxide (N2O): Agricultural activities, such as fertilizer use, are the primary source of N 2 O emissions. Fossil fuel combustion also generates N 2 O. Fluorinated gases (F-gases): Industrial processes, refrigeration, and the use of a variety of consumer products contribute to emissions of F-gases,…
What type of emissions are emitted during fuel combustion?
Relatively small amounts of methane (CH 4) and nitrous oxide (N 2O) are emitted during fuel combustion. In addition, a small amount of hydrofluorocarbon (HFC) emissions are included in the Transportation sector. These emissions result from the use of mobile air conditioners and refrigerated transport.
What are direct emissions?
Direct emissions are produced from residential and commercial activities in a variety of ways: Combustion of natural gas and petroleum products for heating and cooking needs emits carbon dioxide (CO 2), methane (CH 4), and nitrous oxide (N 2O).
What are the environmental side effects of gaseous emissions?
Gaseous emissions into the atmosphere may entail environmental side-effects and may affect human health. Such pollution has been demonstrated, for example, in connection with sulfur oxides from fossil fuel combustion and with photochemical smog.
