The table on the introduction page (see [[Emissions#Inputs|table]]) lists the different sources of emissions  included in the IMAGE model. Emissions that are transported in water (nitrate, phosphorus) are discussed in [[Nutrient balances]]. Regarding the approach and spatial detail for modeling gaseous emissions, IMAGE uses four different ways to represent emissions.

Regarding the approach and spatial detail for modeling gaseous emissions, IMAGE uses four different ways to represent emissions.
* ''World number'' (WRLD). The simplest way to estimate emissions in IMAGE is by using a global estimate from the literature. This approach is used for those natural sources that can not be explicitly modelled.

* ''Emission factor method'' (EF). For other sources in IMAGE, past and future developments in anthropogenic emissions are estimated on the basis of projected changes in relevant economic activities and the emissions per unit of activity (emission factor) (see flowchart on the right).
