Greenhouse gas emissions
The 2008-2009 greenhouse gas (GHG) plan notes an increased focus on energy reduction through the appointment of an energy specialist in late 2007 and the conduct of further energy reviews. A feasibility study is being conducted to examine the possible replacement of power stations to reduce GHG emissions and mitigate current potential environment risk.
A number of additional activities aimed at reducing energy use and GHG emissions are also under way including replacing heavy mobile equipment and locomotives. Dash 7 and Dash 8 locomotives are being replaced by new generation GE EVO locomotives. The RTIO technology group is also examining hybrid locos in collaboration with General Electric, liquid natural gas replacement for diesel trucks and locomotives, rail electrification, and closed cycle power generation for existing open cycle power units. Rio Tinto has approved new gas fired power generation in the Pilbara as a step towards lower emissions electricity.
