CO 2 emissions (Norway) 06 February 2018 3

CO 2 emissions (TiZir Titanium & Iron) Kilde: Miljødepartementet TiZir Titanium & Iron emits 3 % of «Norsk Industri og Bergverk» GHG emissions. Emissions have decreased by 10 % between 2007 – 2014. Decrease mainly due to technical development. 06 February 2018 4
