Stationary Combustion. Default emission factors for CH₄, N₂O, NO_x, CO, and NMVOCs by major technology and fuel types are presented in the Revised 1996 IPCC Guidelines, Reference Manual - Volume 3. Alternative control technologies, with representative percentage reductions are also shown. These data show the range and variation of sources and emission rates, as well as the impact of the control technologies.

Mobile Combustion. Emissions of greenhouse gases (CH₄ and N₂O) from mobile sources can be estimated by major transport activity (road, aviation, railways, and navigation). However, as road transportation account for the majority of mobile- source fuel consumption, followed by air transport, greater priority has been attached to the development of emission models and inventories for road vehicles and aircraft. The diversity of mobile sources and the range of characteristics which affect emission factors are demonstrated and can be seen in the tables included in the Revised 1996 IPCC Guidelines.

Of particular importance for many Parties are N₂O emissions from road transportation, which are significantly affected by the type of emission control technologies in use. Some catalyst-type control technologies increase the rate of N₂O emissions relative to an uncontrolled vehicle.
