MMC Norilsk Nickel's work to upgrade its production lines, implement new technologies and launch projects led to a dramatic reduction in harmful emissions in Russia last year.
Sulphur dioxide emissions decreased by 36.6 thousand tons in 2010, five times greater than 2009, and metal emissions were also reduced including 5.3% for nickel oxide, 12% for cupric oxide, and 20.3% for cobalt oxide.
The company invested around R75bn ($2.56bn) to resolve environmental issues between 2004-2010.
Currently, MMC Norilsk Nickel is building an agglomeration shop, which will provide a 95% decrease in SO2 emissions in Russia. The first agglomeration line is to be launched in first half of 2011.
