On Oct. 10, 2013, representatives from around the world gathered in Japan to formally adopt the text of a new global environmental treaty, the Minamata Convention on Mercury. The treaty now needs 50 countries to ratify it before its pollution prevention measures go into effect.

A United Nations Environment Program website tracks the progress of treaty ratification here.

The official announcement of the treaty signing is here.

Text in the treaty applicable to gold mining is below. Countries where artisanal gold mining takes place and that ratify the treaty will follow a number of steps to reduce and gradually eliminate mercury from gold production.
