Air Emissions Accounts

The term "air emissions" refers to all flows of gas and particulate matter from the economic system (production and consumption processes) into the (domestic and the rest of the world) atmosphere as part of the environment. This implies that only man-made (anthropogenic) and non-natural emissions are taken into account.

Within Air Emissions Accounts, emissions are assigned to economic activities and household consumption according to the ÖNACE classification, which is also used in national accounts.

Specific feature of Air Emissions Accounts is that only those air emissions are considered, which are caused by private households, enterprises and institutions residing in Austria, irrespective of the place where they are produced. In contrast to this, the Environment Agency Austria compiles - within the framework of international reporting obligations (UNFCCC, UNECE CLRTAP) – the Austrian Air Emission Inventory. In the Austrian Air Emission Inventory air emissions that are caused in Austria, independently of the polluters’ origin, are reported. Environment Agency Austria´s Annual Air Emission Inventory forms the basis for the Air Emissions Accounts.

The development of selected air pollutants and greenhouse gases in brief: Sulphur dioxide (SO2), nitrogen oxides (NOx), non-methane volatile organic compounds (NMVOC), methane (CH4), carbon monoxide (CO), carbon dioxide (CO2 – total, from fossil sources, from biogenic sources, from other sources), nitrous oxide (N2O), ammonia (NH3) as well as particulate matter (PM10 and PM2.5). Greenhouse gases also include hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF6) and nitrogen trifluoride (NF3).

In many cases air emissions were reduced considerably between 1995 and 2017. The biggest losses were achieved for SO2 (-70.2%), SF6 and NF6 (-62.9%) as well as NMVOC (-48.3%). But also the emissions of PFC (-47.1%), CO (-41.1%), CH4 (-30.7%), NOx (-22,7%), N2O (-19%), and the much debated particulate matter - represented by PM2.5 (-33.2%) and PM10 (-25.0%)- could be reduced considerably. An increase has been registered in the case of climate relevant CO2 emissions from other sources (+34.2%) and HFC (+388.%). In total there was a slight decrease in CO2 emissions due to the declining CO2 emissions from fossil fuel combustion. Between 1995 and 2017 biogenic CO2 emissions increased by 93.0%.
