Lower emissions from municipalities in 2009
From 2008 to 2009, greenhouse gas emissions were reduced in more than 300 of the 430 municipalities in Norway. The total reduction was approximately six per cent. Emissions from road traffic were three per cent down, while emissions from manufacturing industries were reduced by 17 per cent.
Emissions of the greenhouse gases carbon dioxide (CO 2 ), methane (CH 4 ), nitrous oxide (N 2 O) and fluorinated gases in the municipalities were approximately 36.9 million tonnes CO 2 equivalents in 2009. This is 2.3 million tonnes lower than in the previous year. The reduction was unevenly distributed; 10 municipalities had a reduction corresponding to the total reduction in all the municipalities.
From 1991 to 2009, emissions were reduced by 3.3 per cent. CO 2 emissions increased by 4.9 million tonnes, while the emissions of methane, nitrous oxide and fluorinated gases were reduced by 6.1 million tonnes.

Emissions of fluorinated gases effectively reduced in manufacturing industries
Emissions of fluorinated gases at municipal level are estimated for the first time this year. In 1991, these gases accounted for 13.6 per cent of all greenhouse gas emissions. In 2009, their share constituted 3.2 per cent. The reductions are due to a shut down of magnesium production (main source of SF 6 emissions), and technology improvements in the production of aluminium (main source of PFC emissions). The emissions of HFCs, which are used in cooling, have however increased substantially, relatively speaking. Most municipalities have thus had an increase in the emissions of fluorinated gases, but the total increase in the emissions of HFCs has been much smaller than the total decrease in the emissions of SF 6 and PFCs, measured in CO 2 equivalents.
Greenhouse gases from road traffic reduced in 2009
Greenhouse gas emissions from road traffic were reduced by three per cent in 2009. The reduction is probably temporary because sales of engine fuels have increased again in 2010 (see http://www.ssb.no/petroleumsalg_en ).
Emissions from landfills increased slightly in 2009 (up two per cent from the previous year). Since 1991, emissions have declined by 36 per cent, due to less depositing in landfills and an increase in collection and flaring of methane.
Road traffic still the most dominant source of NO X emissions
NO X emissions in the municipalities were slightly higher than 90 000 tonnes in 2008. Road traffic accounted for 47 per cent of these emissions. Other mobile sources were responsible for 24 per cent of the emissions, while manufacturing industries caused 22 per cent of the emissions.
