[14] [15] [16] One carbon credit represents an emission reduction or removal of one metric tonne of carbon dioxide or the equivalent amount of greenhouse gases that contribute equally to global warming (CO 2 e). [17] [18] Carbon credits are a form of carbon pricing, along with carbon taxes and subsidies.
Microbial electrolysis carbon capture (MECC) is a carbon capture technique using microbial electrolysis cells during wastewater treatment. MECC results in net negative carbon emission wastewater treatment by removal of carbon dioxide ( CO 2 ) during the treatment process in the form of calcite (CaCO 3 ) , and production of profitable H 2 gas.
The terms carbon capture and storage (CCS) and carbon capture, utilization, and storage (CCUS) are closely related and often used interchangeably. [3] Both terms have been used predominantly to refer to enhanced oil recovery (EOR) a process in which captured CO 2 is injected into partially-depleted oil reservoirs in order to extract more oil.

Carbon farming is one component of climate-smart agriculture. It is also one way to remove carbon dioxide from the atmosphere. Agricultural methods for carbon farming include adjusting how tillage and livestock grazing is done, using organic mulch or compost, working with biochar and terra preta, and changing the crop types.
The viscosity of an ionic liquid can vary significantly according to the type of anion and cation, the alkyl chain length, and the amount of water or other impurities in the solvent. [ 11 ] [ 12 ] Because these solvents can be “designed” and these properties chosen, developing ionic liquids with lowered viscosities is a current topic of ...
Liquid water is essential for carbon-based life. Chemical bonding of carbon molecules requires liquid water. [30] Water has the chemical property to make compound-solvent pairing. [31] Water provides the reversible hydration of carbon dioxide. Hydration of carbon dioxide is needed in carbon-based life. All life on Earth uses the same ...
Chemical water analysis is carried out on water used in industrial processes, on waste-water stream, on rivers and stream, on rainfall and on the sea. [1] In all cases the results of the analysis provides information that can be used to make decisions or to provide re-assurance that conditions are as expected.
Carbon concentration in the mantle is very variable, varying by more than a factor of 100 between different parts. [6] [7] The form carbon takes depends on its oxidation state, which depends on the oxygen fugacity of the environment. Carbon dioxide and carbonate are found where the oxygen fugacity is high.
