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 global emission sectors?
In this report, some of the sector categories are defined differently from how they are defined in the Sources of Greenhouse Gas Emissions page on this website. Transportation, Industry, Agriculture, and Land Use and Forestry are four global emission sectors that roughly correspond to the U.S. sectors.
