Greenhouse gas emissions
A greenhouse gas (GHG) performance review was submitted by each business unit as part of a planning process. This included a discussion on targets and performance and a list of proposed and implemented projects noting project progress, savings, costs and NPV (net present value).
Energy Resources of Australia is expected to exceed its targeted GHG reductions. Rio Tinto Energy America is slightly above target and Rio Tinto Coal Australia emissions per tonne have increased. Both RTEA and RTCA have a number of NPV positive optimisations and diesel reduction projects being researched or implemented. With a life of mine extension under way, Rössing Uranium has set a revised target. A number of optimisation projects have been identified.
The Energy group is also focussing on long term emissions reductions through the Hydrogen Energy joint venture. The plan identifies significant expenditure in terms of operating and capital costs for Hydrogen Energy in 2008 and 2009.
