6. Policy for Quality, Health, Safety and Environment In DONG Energy we: • strive for keeping our customers satisfied and consult them on appropriate use of our products. • motivate, train and involve our employees in quality, working environment and environmental work. • work to achieve a healthy and safe working environment. • continuously seek to minimise resource use and environmental impacts. • prioritise suppliers and business partners with quality, working environment and environmental policies which they abide by. • set goals, assess results and continuously improve them, and be the best in the business. • ensure observance of applicable laws and work in accordance with recognised standards and norms. • communicate openly on goals and results in quality, working environment and environment.

7. RESEARCH, DEVELOPMENT AND DEMONSTRATION Within research and development our most important focal points are the development of highly efficient power plants, renewable energy sources and technologies to reduce the impacts on the environment of our power plants. The three main projects right now are: • AD700 – Advanced steam data, 700 degrees Celsius steam temperatureThe objective of the project is to develop new materials which will allow an increase of the boiler steam temperature to 700 °C to ensure a higher output rate and lower CO2 emissions. • CASTOR – CO2 from Capture to StorageThe objective of the project is to separate CO2 from the power plant flue gases and to investigate the possibilities of re-using the carbon dioxide for enhanced oil production in oil fields. • IBUS – Integrated Biomass Utilisation SystemThe objective of the project is to process biomass like straw into ethanol (alcohol) for use as an additive to gasoline. The process is energy-heavy and there are good synergies to be obtained in the production of ethanol in connection with power plants. GENERATION - HCASA

8. Quantification of the environmental impact • The quantification of the environmental impactat different production/consumption • scenarios is important for DONG Energy's • decision process. • The results of CEEH will undoubtably • influence the political process in Denmark. • Therefore it is important for us to follow • the work to see that • right data are used for the CEEH calculations • correct assumptions about future technology are used for the scenarios • Since 1997 DONG Energy have been • investigating our environmental impacts through • Life Cycle Assessments.
