The fifth and final session of the International Negotiating Committee to prepare a global legally binding instrument on mercury (INC5) will take place January 13-18 in Geneva, Switzerland. Established in 2009 by the United Nations Environmental Programme (UNEP) and ministers of the environment from over 140 countries, the committee has the goal of developing an international treaty to curb mercury emissions and discharges in order to reduce this threat to human health and the environment. The committee plans to have all negotiations completed prior to the 27th session of the UNEP Governing Council/Global Ministerial Environment Forum taking place this February in Kenya, and to ratify the treaty later this year in Japan.
