The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without this atmosphere. Radiatively active gases (i.e., greenhouse gases) in a planet's atmosphere radiate energy in all directions. Part of this radiation is directed towards the surface, warming it. The intensity of the downward radiation – that is, the strength of the greenhouse effect – will depend on the atmosphere's temperature and on the amount of greenhouse gases that the atmosphere contains.

An amount of photosynthetic biomass such as wood is converted into coal such as charcoal and a substantial amount thereof is permanently stored until the atmospheric CO2 level is reduced to an extent which is unable to cause a greenhouse effect. While a main portion of the charcoal remains in permanent storage, a fraction thereof may be retained prior to or retrieved during or after achievement of the reduction in the atmospheric CO2 level. Such fraction is converted into energy or an energy source, for example hydrogen, in a manner such that thereby the atmospheric CO2 is maintained at a level which does not cause an undesired greenhouse effect.

Applications of waste gas injection into natural gas reservoirs
InactiveUS20050167103A1Improve liquidityLow viscosityOther gas emission reduction technologiesFluid removalGreenhouseEnvironmental engineering
Natural gas is produced from a reservoir above a bitumen reserve with minimal or no impact on concurrent or subsequent production of bitumen recovery techniques including SAGD. Greenhouse benefits over and above the benefits of coincidental recovery are available through the injection of waste gas containing carbon dioxide for maintaining pressure in the gas reservoir while producing natural gas. Carbon dioxide separates out of the waste gas through preferential absorption in connate or aquifer water, with the result that carbon dioxide is thereby both retarded from flowing to the natural gas production well and effectively sequestered in the reservoir water. Additional advantage is achieved wherein water influx at production wells can be managed and trapped gas can be recovered.
