Oscar Castro-Orgaz,Willi H. Hagern of CO. in the atmosphere has increased from 280 ppm to almost 380 ppm. Known anthropogenic sources account for 7 billion metric tons per year. The principal anthropogenic source is the combustion of fossil fuels, which accounts for about three-quarters of total anthropogenic emissions of carbon wo

The existing strict environmental regulations and the expanding market for organic carbonates do not assure that this technology can continue to have a leading role in this area, due to the inherent riskfulness of the processes.
