Depending on the specific industry, companies use different methods of carbon capture. All of them are quite costly and can be effective only if combined with the company's main business.

— Carbon can be used as a component of a mix for curing cement or other fillers. In this case, the cost of utilizing one tonne of emitted CO₂ will be $30–70.

— If a company uses biomass to produce fuel or other products, microalgae would be fit for carbon capture. However, given the current level of technology, the cost of the process is fairly high, starting from $230 per tonne of CO₂.

— CO₂ can be is combined with hydrogen to produce methanol, synthetic fuel, and synthesis gas. This gives an opportunity to utilize additional amounts of CO₂. But the costs are currently as high as $670 per one tonne of CO₂.

— Another way of greenhouse gas sequestration is the use of carbon dioxide for oil extraction. In line with this approach, CO₂ captured at coal-fired power plants is then transported to old, nearly depleted oil fields. CO₂ injected into the wells causes hard-to-recover oil to "pop" deep underground. The oil becomes less viscous and readily flows through the old well. The cost of capture is $40-60 per tonne of CO₂.

— CO₂ capture is also possible through the use of catalysts and chemical reactions. This method allows producing methanol and carbamide (a fertilizer containing 46% of nitrogen), as well as polymers. In this case, sequestration cost would be $80-300 per tonne of CO₂.
