Siemens Remains Committed toDesigning and Building Clean, EfficientPower Plants Worldwide

By investing significant R&D in advanced coal technologies including

Ultra Supercritical Plants Integrated Gasification CC Plants

By investing heavily in large manufacturing plants worldwide, includingChina

The technology is available the manufacturing is available

all that is needed is a commitment to use our precious resourcesmore effectively

What Should we do to Protect theEnvironment for Future Generations?

For Countries Rich in Natural GasBuild high efficiency combined-cycle plants (but plan fuel diversity)

For Emerging Countries with Small Installed Grids and low Natural GasReservesBuild small (250-500 MW) coal plants using modern day subcriticaltechnology with low NO X burners and post-combustion emissionscontrols for SO 2 and particulates

For Emerging Countries Rich in Coal with Large Installed Grids and MatureCountries Rich in Coal

Continue to clean up/retire old coal-fired operating units

Build large (600-1000 MW) supercritical/ultrasupercritical coal plantswith post-combustion emissions controls for NO X, SO 2 and particulatesEmbrace IGCC as it becomes more commercially availableContinue development toward CO 2 capture

How Can the World Financing CommunityHelp?

Bring Emission Guidelines in line with requirements in rest ofthe world and available technologies

Stipulate efficiency thresholds to promote advanced coaltechnologies

Promote carbon credits to effectively reduce CO 2
