Annual emissions of nitrogen oxides (NOx) will not exceed 156 000 tonnes from 2010 onwards, and annual emissions in the period up to 2010 will not exceed the 1987 level (218 000 tonnes).
Norway’s NOx emissions rose steeply until 1986. From 1986 to 1992, there was a drop in emissions as a result of the introduction of stricter exhaust standards for road vehicles and an economic downturn. After 1992 emissions rose until 1999. From 1999 emissions have decreased.
Norway's NOx emissions totalled 167 000 tonnes in 2009, according to preliminary figures from Statistics Norway. This was 11 000 tonnes higher than the emission ceiling for 2010 set out in the Gothenburg Protocol. Emissions will probably be reduced in the coming years, partly because stricter exhaust standards have already been adopted.
