The Executive Committee, having noted the comments of the Sub-Committee (UNEP/OzL.Pro/ExCom/23/10/Add.1, paragraphs 38 and 39), as well as the views expressed in the course of the discussion, decided to request the Sub-Committee on Project Review to reconsider, during 1999, the question of guidelines for the tobacco sector as a whole, with a view to determining whether the circumstances then prevailing with regard to cost-effectiveness thresholds would allow further work to be done in that sector.
