Abstract:	As a consequence of rising CO2 level in the atmosphere the temperature on the surface of the Earth is rising (Global warming). The CO2 level is around 385 ppm (v) nowadays and still increasing. The two main reasons are: power plants using coal, oil or gas, and the growing number of cars. The possibility of capture and storage of CO2 (CCS – Carbon Capture and Storage) has been studied. Scientists agree we have to stop the rising level of CO2 at around 450-500 ppm (v). We may use natural (photosynthesis) or industrial processes. We have the following industrial possibilities: new technologies using less energy, nuclear energy, renewable energy (solar, wind, power wood), CCS (deep ocean, depleted oil-gas reservoirs), methanol economy. In this presentation the selected methods of CCS will be discussed.
Keywords:	global warming, CO2, greenhouse effect, carbon capture and storage, methanol economy
