The document discusses the need to control CO2 emissions and various methods for doing so. It explains that CO2 and other greenhouse gases trap heat in the atmosphere and are causing global climate change. It then outlines different technologies for capturing CO2 from power plants, such as solvent absorption and membrane separation. Finally, it discusses options for storing captured CO2 underground or in the oceans and shifting to non-fossil energy sources like solar, wind and geothermal to reduce CO2 emissions.
