Emissions to air, 1990-2001

Norway has signed the Kyoto Protocol, and is commited to increase the emissions in 2008-2012 by no more than 1 per cent from the 1990 level. Norway's total greenhouse gas emissions have, however, increased by as much as 8 per cent in the period 1990-2001. In 2001, CO₂ made up three quarters of the Norwegian greenhouse gas emissions, measured as CO₂ equivalents. This gas also accounts for almost all of last year's increase in total emissions. The increase was 1 per cent or 600 000 tonnes.

Emissions from electricity production offshore (gas turbines) increased by 11 per cent from 2000 to 2001, while emissions from flaring were reduced by 19 per cent. Combustion emissions from oil and gas production alone now make up 19 per cent of the Norwegian greenhouse gas emissions measured as CO₂ equivalents. These emissions have doubled from 1990.

CO₂ emissions from road traffic increased by 7 per cent from 2000 and road traffic now makes up 22 per cent of the CO₂ emissions. The Norwegian road traffic index shows an increase from 2000 of 2.4 per cent in driven kilometers on Norwegian roads, which is somewhat lower than the emission increase.

In 2001, the use of oil products in manufacturing industries was approaching the 1999 level after a reduction in 2000. This led to an increase in emissions of greenhouse gases for some manufacturing industries, compared with the preceding year.

Emissions from industrial processes have declined somewhat, due to a slump affecting parts of the industry. The decrease was highest for production of ferroalloys, where reduced production led to a 7 per cent reduction in CO₂ emissions in 2001, compared with the preceding year.

Emissions from nitrogen oxides, NMVOC and ammonia are treated in a separate article .
