Scientists use inventories of natural and anthropogenic (human-caused) emissions as tools when developing atmospheric models.

Scientific use: Inventories of natural and anthropogenic emissions are used by scientists as inputs to air quality models.

The majority of atmospheric anthropogenic emissions are released as gaseous elemental mercury.

Although anthropogenic emissions of sulphur dioxide account for only half of the total global emission, they tend to be very concentrated.

Global anthropogenic emission of oxides of nitrogen for 1980 were estimated at 75 million tonnes.

Flaring constitutes a hazard to human health, and is a contributor to the worldwide anthropogenic emissions of carbon dioxide.

Characterizing the accumulated human effect on climate also enables us to predict what happens to future climate if we stop all anthropogenic emissions today.

It quantifies the anthropogenic emissions and natural exchanges of trace gases and aerosols that drive Earth system changes.

Most of the data indicate that the changes in eco-systems are the consequence of anthropogenic emissions and indicate possible trends for the future.

It is also useful to extend the monitoring system to include anthropogenic emissions and reductions.
