Helsinki Declaration on the Protection of the Ozone Layer (1989)

The Governments and the European Communities represented at the First Meetings of the Parties to the Vienna Convention and the Montreal Protocol

Aware of the wide agreement among scientists that depletion of the ozone layer will threaten present and future generations unless more stringent control measures are adopted

Mindful that some ozone depleting substances are powerful greenhouse gases leading to global warming

Aware also of the extensive and rapid technological development of environmentally acceptable substitutes for the substances that deplete the ozone layer and the urgent need to facilitate the transfer of technologies of such substitutes especially to developing countries

Encourage all states that have not done so to join the Vienna Convention for the Protection of the Ozone Layer and its Montreal Protocol

Agree to phase out the production and the consumption of CFCs controlled by the Montreal Protocol as soon as possible but not later than the year 2000 and for that purpose to tighten the timetable agreed upon in the Montreal Protocol taking due account of the special situation of developing countries

Agree to both phase out halons and control and reduce other ozone-depleting substances which contribute significantly to ozone depletion as soon as feasible

Agree to commit themselves, in proportion to their means and resources, to accelerate the development of environmentally acceptable substituting chemicals, products and technologies

Agree to facilitate the access of developing countries to relevant scientific information, research results and training and to seek to develop appropriate funding mechanisms to facilitate the transfer of technology and replacement of equipment at minimum cost to developing countries.

Helsinki, 2 May 1989
