CARMA as source for estimate Hi Could you have a look at this again please I and another user have checked the references provided by Gnangarra and don t believe they have actual emissions of GHGs or CO2 The NPI only shows CO1 In the circumstances I believe that CARMA can be used for estimates saying something like START CARMA estimates this power station emits 4 33 million tonnes of greenhouse gases each year Kogan Creek Power Plant Plant overview Carbon Monitoring for Action Retrieved on 23 November 2007 The Australian Government has announced the introduction of a Carbon Pollution Reduction Scheme commencing in 2010 which is expected to impact on emissions from power stations END If official figures were to become available I agree they shoud be used Thanks Phanly
