List of Priority Substances

Norway is aiming to reduce emissions of substances that pose a serious threat to health or the environment continuously, with a view to eliminating them completely by 2020. The priority list includes about 30 named substances and groups of substances. In addition, the national target applies to other substances that meet specified criteria. The first version of the priority list was published in 1997, in a white paper on an environmental policy for sustainable development.

Criteria for priority substances

A set of criteria has been drawn up for identifying priority substances. These include substances that are persistent and bioaccumulative, that have serious long-term health effects, or that show high ecotoxicity.

Steps to reduce releases

Releases of many priority substances have been substantially reduced since 1995. Norway has taken action at national level to reduce or eliminate releases of nearly all priority substances. There are also international agreements to phase out or restrict the use of many of these chemicals.

Nevertheless, some priority substances are still in use for certain purposes, and not all sources of pollution have been phased out. In addition, pollutants and waste released in the past can still create problems today. The environmental authorities are therefore continuing efforts to reduce releases of these substances even further.
