Abstract
Method and system are disclosed for the production and use of a chemical compound, where a given amount of CO2 is emitted in the production and the use, including producing a second chemical compound that is required for the production or the use of the first compound, where the production of the second compound consumes CO2 and sequesters it from the atmosphere so that the total net CO2 emitted in the production and use of the first compound is now reduced. In one embodiment, the second chemical compound is a negative-CO2-emissions hydrogen, oxygen or chlorine gas produced in an electrolytic cell.
