On May 10, the two-week joint Conference of the Parties (COP) talks on the Basel, Rotterdam, and Stockholm conventions on chemicals and hazardous waste concluded in Geneva. During the talks, efforts to come to an agreement halted when African and Latin American representatives said they would not support proposals introduced by Canada, the European Union, and Japan. The proposals set exceptions to the guidelines that define waste. Industry groups advocated for the exceptions and urged a consensus agreement be reached.
