Carbon black (Color Index International, PBK-7) is the name of a common black pigment, traditionally produced from charring organic materials such as wood or bone. It appears black because it reflects very little light in the visible part of the spectrum, with an albedo near zero.
Globally, reducing black carbon will mean reducing prescribed burns in eastern Europe so that black carbon emission and depositing does not occur in spring as radiation is increasing and the area of snow/ice pack is large.
