NOx emissions must be reduced sharply

According to the Gothenburg Protocol, Norway will have to reduce the emissions of NOX and NMVOC by 30 and 50 per cent respectively within 2010.

The new figures for 2001 show only a slight decrease in the NOX emissions, while the emissions of NMVOC has risen from 2000. The reduction in the NOX emissions is mostly due to reduced flaring in the oil fields and reduced activity in manufacturing of ferro-alloys, but also in national sea traffic.

The highest share of the NOX emissions comes from national sea traffic. Ships accounted for 39 per cent of these emissions in 2001 (international sea traffic is not included). For road traffic, the share was 22 per cent.

59 per cent of Norway's NMVOC emissions are now generated from evaporation during loading of crude oil offshore.

In the Gothenburg Protocol Norway has undertaken to meet an emission ceiling of 23 000 tonnes NH3 in 2010. The emissions for 2001 are near 25 000 tonnes, where 90 per cent comes from agriculture. Statistics Norway and the Norwegian Pollution Control Authority are working with improvements of the calculation methods for NH3. The new methods are expected to give lower NH3 emissions.
