What is green coke CBM?
Green = environmentally friendly (non-polluting). Coke = coal that has been heated in the absence of air (contains more energy than the same volume of coal). CBM = coal-bed methane (naturally occurring gas found in coal beds). It is a greenhouse gas if allowed to escape into the atmosphere, but if captured it can be used as a non-polluting fuel - probably to turn the coal into coke.
