Persistent Organic Pollutants (POPs)

The Stockholm Convention on Persistent Organic Pollutants (POPs) is a global treaty designed to protect human health and the environment from organic chemicals which are so stable that they remain in the environment for many years. These chemicals become widely distributed geographically and are also prone to accumulate in living organisms. The text of the Convention was adopted on 23 May 2001 and entered in to force on 17 May 2004.

The Convention initially identified 12 POPs (the so-called "dirty dozen") and requires Parties to take specific measures to control their manufacture, use, release and disposal. It also established a mechanism for identifying new potential POPs, their scientific evaluation and establishing what measures are needed to protect human health and the environment. In 2009 nine substances were added to the list of POPs, in 2011 another one (endosulfan) bringing the total to 22 'POPs'.

Challenges and industry support

The Convention requires the use of Best Available Techniques and Best Environment Practices (BAT/BEP) in order to minimise the emissions of unintentional POPs.

The Stockholm Convention on POPs is a key treaty with far-reaching implications, which are being discussed in a number of international fora. The challenge for the chemical industry is to ensure that a science- and risk-based approach is the basis for the nomination and assessment of candidate chemicals that may in future be considered as POPs. 

Euro Chlor is closely monitoring developments with regard to this general challenge and is specifically following the evaluation of some chlorinated chemicals which are discussed in the context of the Convention.  Euro Chlor has also contributed to the debate with the EU Commission on establishing concentration limits for POPs in waste.

Under the umbrella of the World Chlorine Council, Euro Chlor has contributed to the development of guidelines for the environmentally sound management of persistent organic pollutant wastes. Likewise, the chemical industry has assisted in developing BAT and BEP Guidelines and the Basel POPs Waste Guidelines.  BAT/BEB guidelines are developed as general guidance, recognising that local conditions, resources and economics should be taken into account.

The application of these techniques and practices by numerous countries has been successful in dramatically reducing releases of unintentional POPs and in safely managing POPs wastes. These guidelines should also help resolve unjustified accusations that have been made during the past ten years or so against the chlorine and PVC industries regarding release of the unintentional by-products dioxins and furans.

Euro Chlor continues to track the implementation of the Stockholm Convention on POPs and is committed to a science-based, transparant and effective implementation in close co-operation with our chemical industry sectors, the World Chlorine Council and the International Council of Chemical Associations (ICCA).

UPDATE - 13 February 2017 - SCCP under the Stockholm Convention

During the last POPRC meeting, the Annex F (risk management evaluation) for SCCP was approved and the recommendation given to discussion at the 2017 COP in Geneva was given that SCCP be listed on Annex A - elimination without specific exemptions. Incorrect assumptions about SCCP in other chlorinated alkanes and an erroneous assessment of alternatives were noted by many. Questions from several parties (signatory countries) also remain over the scientific rigour of the process and if SCCP meets the requirements for Annex E (risk profile, which passed in 2015) but these will be discussed at the COP in late April/ early May 2017.

Hexachlorobutadiene (HCBD) was suggested for listing in Annex C again after being sent back to the COP due to concerns with the quality of the Annex F document. It will also be discussed in May 2017.
