Asbestos: Should Canada block move to call chrysotile hazardous?

Canada has moved to block listing chrysotile asbestos on an international list of hazardous substances at a UN summit in Switzerland.
Delegates at the summit are determining whether asbestos should be listed in a United Nations convention treaty known as the Rotterdam Convention. Adding it to the Annex III list of the treaty would enable countries where companies import asbestos to turn it away if they don’t think it will be safely handled.
The Rotterdam Convention requires consensus before any change can be made to the list. The only countries still objecting are Canada, Kazakhstan, Kyrgyzstan and Vietnam.
