Japan, 140 countries adopt groundbreaking treaty to cut mercury emissions

AP, Kyodo

GENEVA - More than 140 nations including Japan on Saturday adopted the first legally binding international treaty aimed at reducing mercury emissions, capping four years of negotiations on what limits to set on the use of the highly toxic metal.

The accord was adopted after all-night negotiations that capped a week of talks in Geneva, according to U.N. environmental officials and diplomats.

In accordance with Japan's proposal, the treaty will be named the Minamata Convention after the city in Kumamoto Prefecture that has given its name to a mercury-poisoning disease caused by the discharge of wastewater laced with the harmful heavy metal by a local chemical plant. The facility was operated by chemicals maker Chisso Corp.

The draft document for the treaty will be adopted at an international conference to be held in the prefecture in October. Fifty nations must ratify the pact before it enters into force, which officials expect to take approximately three to four years.

"To agree on global targets is not easy to do," Achim Steiner, executive director of the U.N. Environment Program, told a news conference. "There was no delegation here that wished to leave Geneva without drafting a treaty."

The draft document's preamble notes the need to prevent future damage based on the lessons learned from Minamata disease, a clause proposed by the Japanese government. The neurological disorder caused by acute mercury poisoning was officially recognized for the fist time in the 1950s.

In principle, the treaty would ban the manufacture, export and import of products that contain a certain level of mercury, such as thermometers and fluorescent lights. It also seeks to reduce the discharge of mercury into the air, water and land, to promote its proper storage and disposal, and to cut down on the use and discharge of mercury in the process of gold mining in developing countries.

"We have closed a chapter on a journey that has taken four years of often intense but ultimately successful negotiations, and opened a new chapter toward a sustainable future," said Fernando Lugris, the Uruguayan diplomat who chaired the negotiations.

But some proponents of a new mercury treaty voiced dissatisfaction over the proposed agreement.

Joe DiGangi, a science adviser with advocacy group International POPs Elimination Framework, which aims to eradicate persistent organic pollutants (POPs) through an international network of nongovernmental organizations, said that while the treaty is "a first step," it is not stringent enough to achieve its aim of reducing overall emissions of mercury.
