One of the objectives of ICP Forests is to provide policy-makers and the general public with relevant information on the long-term effects of air pollution, climate change and other stressors on forest ecosystems.

The Programme does so by publishing regular reports on long-term effects from acidification, eutrophication, ozone as well as other relevant impacts on forest ecosystems.

It also shares its data and infrastructure with the scientific community worldwide and publishes articles in scientific journals.

The ICP Forests Manual ensures the compliance with standardized methods and additional measures for quality control and assurance in every member state and survey thereby making ICP Forests unique in global forest monitoring efforts.
