Adjacent to the active sites in operation, ArcelorMittal owns a significant amount of land for future expansion on which industrial activities have taken place in the past. ArcelorMittal systematically reviews land rehabilitation when site restructuring is concerned and has undertaken a number of biodiversity studies. Furthermore, in Brazil we grow forests of eucalyptus trees. The forest growth is the highest in the world with 3,000 m3 per km2 per year. Wood from these forests is used to produce charcoal for the production of pig iron. Through this process, metallurgical coke is substituted by charcoal giving rise to net CO2 savings.
