What are the timelines and deadlines associated with the Challenge?
Under the Challenge, the approximately 200 substances of highest priority have been divided up into a number of smaller groups (“batches”) of substances, which are being addressed sequentially. These batches comprising all of the substances will be launched within a three-year timeframe.Timelines for the activities on each of these batches are being posted on the Chemical Substances Website, as each new batch is launched. Refer to the appropriate link for each batch under the Challenge.
