Rotterdam Convention

Rotterdam Convention

The Rotterdam Convention of 1998 empowers countries to make informed choices about whether to allow imports of chemicals and pesticides that pose threats to the environment or human health. The treaty entered into force in 2004.

It was created because some countries lack the infrastructure and technical capacity to monitor the import and use of hazardous chemicals.

There were also growing concerns that companies were using developing countries as ‘dumping grounds’ for hazardous substances that were banned or otherwise controlled elsewhere.

The treaty enables importing countries to either give their prior informed consent (PIC) to accept hazardous chemicals, or to choose instead to refuse imports of chemicals they do not want or cannot manage safely.

The convention covers pesticides and industrial chemicals that parties to the convention have been banned or severely restricted for health or environmental reasons, and which parties have nominated for inclusion.

These substances are listed in Annex III of the convention, which currently lists over 40 chemicals, 30 of which are pesticides.

Each party to the convention receives a ‘decision guidance document’ (DGD) that describes each listed chemical, the risks involved with its use, and any bans in place.

Parties then have nine months to decide whether to permanently ban, to allow imports and use of the chemical, or to make an interim decision.

Parties then inform the PIC secretariat which notifies every other party’s designated national authority. To be ‘trade neutral’, a party cannot ban imports of a chemical that it continues to produce domestically.

The responsibility for upholding any import ban under the Rotterdam Convention lies with the exporting nations.

The convention also requires each party let others know if it bans or severely restricts a chemical domestically. If such a party continues to export a newly-controlled chemical it must notify all importing parties.

New chemicals can only be added to the list controlled by the convention if countries in two different regions nominate them to the Chemical Review Committee’s annual meeting, and if all parties later agree to the listing at a Conference of Parties, which takes place every two years.

The treaty is one of many Multilateral Environmental Agreements (MEAs). Its full title is the Rotterdam Convention on the Prior Informed Consent (PIC) Procedure for Certain Hazardous Chemicals and Pesticides in International Trade.

To improve coordination between related MEAs, the first joint Conference of Parties to the Rotterdam Convention, the Basel Convention and the Stockholm Convention was held in 2010.

Journalists should be aware of the vested interests that can dictate decisions made under the Rotterdam Convention. As a chemical can only be listed by consensus, countries that are major producers can be reluctant to allow the listing, even if the chemical is banned at home.

Chemical companies are also involved in the Rotterdam Convention processes, lobbying for looser controls and publishing research that supports their case.

Journalists should assess any studies about chemicals proposed for inclusion in the convention very carefully, to identify how the research was funded and to get an independent scientific opinion on its findings.

The Earth Negotiations Bulletin provides daily reports during each Conference of Parties to the Rotterdam Convention and is a good source of neutral information on each negotiating session.

The bulletin is produced by the International Institute for Sustainable Development, which also runs Chemicals-L, an email-based mailing list for news and announcements about chemical policy, which is another good source for journalists.

Journalists in developing nations can find stories by visiting small-scale farmers and seeing if they are using any pesticides that are covered by the Rotterdam Convention, and which their country has chosen not to import.

Journalists in industrialized nations can focus on chemicals that are banned at home but still exported to less developed nations.

Civil society organizations that take a special interest in the Rotterdam Convention include Pesticide Action Network International which fights against pesticide usage and the Rotterdam Convention Alliance.


One the most contentious chemicals that have been proposed for inclusion in the Rotterdam Convention is a form of asbestos called chrysotile.

Asbestos is widely banned around the world because of concerns about serious health problems in people who are exposed to them. It was proposed for inclusion in the Rotterdam Convention some years ago.

In both cases, however, countries that produce this chemical have blocked their inclusion in Annex III.

The International Ban Asbestos Secretariat accuses Canada, India and Ukraine of blocking the addition of chrysotile. Each of these countries is a major producer.
