Vale’s Clean AER Project is the largest single environmental investment in the history of Sudbury. The $1 billion investment will reduce sulphur dioxide levels by 85% from current levels and significantly reduce metals and particulate emissions. By reducing natural gas consumption and modifying certain processes, the Clean AER Project will also reduce greenhouse gas emissions by 40%.
