World Agrees on a Treaty Restricting Mercury

After protracted negotiations that spanned almost half a decade more than 140 countries have signed on to the world's first legally binding international agreement to control mercury emissions. The agreement puts in place rules that limit mercury emissions from power plants and industrial boilers as well as certain kinds of smelters handling metals like zinc and gold. The treaty phases out mercury laden products, like batteries and thermometers as well as certain types of fluorescent lamps, soaps and cosmetics. The agreement also establishes rules for direct mining of mercury and addresses safe storage of mercury waste.

UNEP Mercury Study: Levels of the Toxic Metal are Increasing

A UNEP study released in January 2013 found mercury pollution in the top layer of the world’s oceans has doubled in the past century. In the past 100 years, man-made emissions have caused the amount of mercury in the top 100 metres of the world's oceans to double. Concentrations in deeper waters have increased by up to 25 percent. The study also indicates that hundreds of tons of mercury have leaked from the soil into rivers and lakes around the world. The report says an estimated 260 tonnes of mercury - previously held in soils - are being released into rivers and lakes.

Legally Binding Treaty to Reduce Mercury Emissions

On Sunday January 13 delegates from more than 130 nations began a final round of negotiations with the intent of creating the world's first legally binding treaty to reduce mercury emissions. Mercury contamination is a major problem which has serious implications for pregnant women, women of childbearing age and young children. Mercury accumulates in fish and wildlife and goes up the food chain.

According to the U.N. environment program, which is also one of the sponsors of these talks, over the past century ocean based mercury contamination has doubled. The report demonstrates that hundreds of tons of mercury have leaked from the soil into rivers and lakes around the world. High rates of mercury pollution are largely attributable to coal burning, chemical production and small-scale mining, particularly what is known as artisanal gold production.

The Natural Step Framework

The Natural Step (TNS)Framework it is a comprehensive model for planning in complex systems. It is openly published and free for all to use. The TNS Framework is based on systems thinking; recognizing that what happens in one part of a system affects every other part. This scientifi­cally rigorous Framework gives organisations the tools to perform a gap analysis using the lens of sustainability, and then work toward closing the gap. Furthermore, The Natural Step Framework complements other sustainability tools and methodologies, such as life cycle analysis or environmental management systems, by providing the context and strategic vision that makes them more effective.
