In its resolution 3/9, the United Nations Environment Assembly invited the COP to consider updating the technical guidelines for the environmentally sound management (ESM) of waste lead-acid batteries. It was recommended during the OEWG-12 face-to-face meetings that the COP should decide to update those technical guidelines.

At its fifteenth meeting, by decision BC-15/11, the COP decided to update the technical guidelines on ESM of waste lead-acid batteries and to develop a draft of the technical guidelines on ESM of waste batteries other than waste lead-acid batteries for consideration during COP-16. For more information, please refer to the Technical Guidelines.
