Claim 0:
1. A method for reducing carbon dioxide emissions, the method comprising:
(a) contacting a flue gas from a source with a carbon dioxide adsorbing material to reversibly adsorb CO2 from the flue gas thereby generating an adsorption material enriched for CO2;
(b) reducing the concentration of CO2 from the flue gas to less than 15,000 ppmv; and,
(c) stripping a portion of the CO2 from the adsorption material enriched for CO2 using a regeneration process,
wherein the carbon dioxide adsorbing material comprises a tetraamine functionalized metal organic framework.
