Emissions from households are basically from domestic heating. The emissions presented for the households sector are calculated by applying activity data combined with emission factors.
What information is to be found here?
Emission factors are developed by applying knowledge about the kinds and amounts of pollutants from combustion of fuels in household stoves. This is combined with information about the kinds of stoves that are used in Norwegian households as well as information about user habits.
Information on the consumption of wood is derived from the annual survey by Statistics Norway where information about consumer products is gathered. Data about consumption of coal is collected from the imports statistics, while the data about gas consumption is gathered from the gas dealers in the market. The sales statistics about petroleum products form the basis for data about heating oil.
The amount of emissions from household/domestic heating can then be calculated by combining emission factors and activity data.
What is not included here?
The household sector includes emissions from households regarded as point sources only. Hence, emissions from activities related to households linked to other sectors are not included in the household sector on the web site. For example, emissions from mobile sources like cars and lawn mowers are found in the transport sector. Emissions from incineration of household waste are listed in the industry sector.
The data for the households sector is published about one year after the collection of the data. Emissions that occurred in 2009 will be published at the beginning of 2011.
