Climate risk and decarbonization: What every mining CEO
The mining industry generates between 1.9 and 5.1 gigatons of CO 2 equivalent (CO 2 e) of GHG emissions annually. The majority of emissions in this sector originate from fugitive coal-bed methane that is released during coal mining (1.5 to 4.6 gigatons), mainly at underground operations. 7

Carbon monoxide Wikipedia
Carbon monoxide has a computed fractional bond order of 2.6, indicating that the "third" bond is important but constitutes somewhat less than a full bond. Thus, in valence bond terms, C≡O + is the most important structure, while :C=O is non-octet, but has a neutral formal charge on each atom and represents the second most important resonance contributor.

Climate risk and decarbonization: What every mining CEO
A global carbon price, investments to decarbonize operations, and strong growth in commodities requiring the opening of new mines would increase mining costs, leading to higher commodity prices. The commodities at stake and the potential price growth are functions of how and at what pace decarbonization occurs.

Activated carbon Wikipedia
Activated carbon, also called activated charcoal, is a form of carbon processed to have small, low-volume pores that increase the surface area available for adsorption or chemical reactions. Activated is sometimes substituted with active.. Due to its high degree of microporosity, one gram of activated carbon has a surface area in excess of 3,000 m 2 (32,000 sq ft) as determined by gas adsorption.

Carbon Wikipedia
Carbon (from Latin: carbo "coal") is a chemical element with the symbol C and atomic number 6. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds.It belongs to group 14 of the periodic table. Carbon makes up only about 0.025 percent of Earth's crust. Three isotopes occur naturally, 12 C and 13 C being stable, while 14 C is a radionuclide

What You Should Know About Metallurgical Coal
Aug 21, 2020 Metallurgical coal differs from thermal coal, used for energy and heating, by its carbon content and its caking ability. Caking refers to the coal's ability to be converted into coke, a pure form of carbon that can be used in basic oxygen furnaces. Bituminous coal—generally classified as a metallurgical grade—is harder and blacker.
