Are we moving in the right direction?
In Norway the total area where critical loads for acidification of water is exceeded has decreased the last 20 - 30 years. 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. In 2005, the area with exceedance of critical loads were reduced to 10 per cent of the total area.
