Reduced acidification


4.1 Pollution will not cause injury to health or environmental damage.


Area where critical loads for acidification are exceeded

Are we moving in the right direction? Published by the Norwegian Environment Agency

In Norway the total area where critical loads for acidification of water are exceeded has gradually decreased.

Inputs to Norway were highest around 1980, when critical loads were exceeded in about 30 per cent of Norway's area. Inputs of sulphur and nitrogen to Norway have declined as emissions in Europe have been reduced.



During the period 2002-2006, the area with exceedance of critical loads was reduced to 11 per cent of the total area, and in 2012-2016 the area had decreased to 7 per cent.

The data are updated every five years. The next update is in 2022.

Calculations suggest that even if the new Gothenburg Protocol is fully implemented, lakes in acid-sensitive areas in Norway will continue to have acidification problems. We therefore have not yet completely met our target.
