CIPK stands for Carbon Intensity per Kilowatt-hour. It is a measure of the carbon dioxide emission content, in grams, of a kilowatt-hour (3.6 million joules) of energy. It is a function of the carbon content of the fuel being used to produce the energy. If the fuel contains no carbon, or if carbon does not participate in the process that produces the energy, then the CIPK is zero.
