The ozone layer is the Earth's natural sunscreen, filtering out harmful ultraviolet (UV) rays from the sun. UV rays can cause damage to humans and other forms of life.
Although the ozone layer is high up in the atmosphere, chemical substances used at the surface of the planet can damage it. If the ozone layer is damaged, UV rays can get through and cause damage to humans and other forms of life.
Therefore, the ozone layer must be protected from these chemicals so that it can recover from the damage over many years.
One of the chemicals used that damages the ozone layer is a refrigerant gas known as R22. This gas (a hydrochlorofluorocarbon or HCFC) is one of the last remaining ozone depleting subtances that is in common use. However, R22 will be completely banned at the end of 2014.
A series of guidance leaflets has been produced to provide more information on R22 phas-outin the affected sectors.
The Montreal Protocol is considered to be the most successful global environmental agreement setting out commitments by every country in the world to eliminate production and use of the chemicals that damage the ozone layer. The effectiveness of the Montreal Protocol is monitored by the Ozone Secretariat of the United Nations Environment Programme.
2012 marked the 25th anniversary of the Montreal Protocol and 16th September each year is designated as International Day for Preservation of the Ozone Layer. To mark the 25th Anniversary of the Montreal Protocol, the European Union's Commissioner for Climate Action, Commissioner Connie Hedegaard, prepared a short video.
The European Union is marching ahead in terms of phasing out the chemicals that damage the ozone layer, known as ozone depleting substances (ODS), through a law that is stricter than the Montreal Protocol. The most recent legislation was published in October 2009.
In Ireland the Environmental Protection Agency (EPA) is responsible for making sure the European law is implemented and properly enforced. Certain responsibilities have also been given to the following organisations to assist the EPA:
The EPA and these other organisations continue to work together to increase awareness in the various sectors involved in handling ozone depleting substances and to ensure compliance with the law.
There is a list of more than 20 substances that are controlled by the European law on ozone depleting substances and there are bans and restrictions on their production, import, export, placing on the market, use, recovery, recycling, reclamation and destruction. These substances are grouped and their common historical uses are presented for information:
The European Regulation controlling ozone depleting substances came into effect in January 2010, having replaced the previous Regulation from 2000. Regulation (EC) No. 1005/2009 introduces a number of extra requirements relating to leak checking, reporting, import and export licensing etc.
