Emissions to air, by municipality, 1991-2000

The figures are calculated by Statistics Norway in cooperation with the Norwegian Pollution Control Authority.

Greenhouse gas emissions increase

Emissions of the three most important greenhouse gases; carbon dioxide (CO₂), methane (CH₄) and nitrous oxide (N₂O) rose by 13 per cent in Norwegian municipalities in the period 1991-2000. The largest sources of these emissions in most municipalities are manufacturing industry, road traffic, agriculture and landfills. The rise is mainly caused by increased emissions from industrial plants and road traffic.

Emissions up 6 per cent in Oslo

By studying the emission tables, which can be downloaded here, it is possible to see what emission sources contribute the most to emissions in your municipality. In Oslo, road traffic accounted for nearly half of the emissions of greenhouse gases in 2000. The time series table shows that in Oslo, emissions of the three mentioned gases have increased by 6 per cent from 1991 to 2000.

Local air pollution

Emissions of particulate matter (PM_{1 0}) and nitrogen oxides contribute to poor air quality many places in Norway. As for particulates, emissions from the use of fuel wood in private households and road traffic (exhaust and asphalt dust) are most noticeable. For nitrogen oxides, road traffic is the dominating source, although these emissions have decreased during the nineties.
